Patru piese din Inconel 718 pentru temperaturi înalte — flanșe, conectori, componente structurale periferice ale turbinei și șuruburi pentru aplicații la 600–700°C în serviciu continuu. Inconel 718 durificat prin precipitare (AMS 5662, condiție îmbătrânită) atinge 1380 MPa rezistență la tracțiune UTS — cea mai mare rezistență UTS dintre superaliajele standard prelucrate, fiind alegerea implicită acolo unde sunt necesare simultan temperaturi înalte și sarcini mecanice mari. Piese prelucrate în condiție de soluție-îmbătrânire, apoi întărite prin îmbătrânire după prelucrare pentru a minimiza timpul de prelucrare în condiția mai dură de îmbătrânire.

Five nickel alloy corrosion-resistant parts — Hastelloy C-276 valve bodies, pump-valve parts, nozzles, sealing bodies, chemical reactor fittings, and marine parts. Hastelloy C-276 provides the broadest chemical resistance of commercially available alloys — resistant to both oxidising acids (nitric, chromic) AND reducing acids (hydrochloric, sulphuric), chloride environments, and wet chlorine gas. Where a single alloy must withstand mixed acid environments that would corrode SS316L, titanium Grade 2, and Inconel 625, C-276 is the standard specification. Inconel 625 for applications requiring both corrosion resistance and higher temperature service.

Hastelloy C-276 Valve Bodies & Pump-Valve Parts
Hastelloy C-276 (UNS N10276, ASTM B574/B575) corrosion-resistant valve bodies and pump wear parts for the most aggressive chemical processing environments — hydrochloric acid at all concentrations and temperatures, sulphuric acid up to 50% concentration at 80°C, wet chlorine gas, hypochlorite solutions, and mixed acid environments where all austenitic stainless steel grades and titanium Grade 2 corrode. The broadest-spectrum chemical resistance of any machined alloy — Hastelloy C-276 resists both oxidising and reducing acids simultaneously by a synergistic Ni-Cr-Mo passive film mechanism. Valve body: bore H7; thread 4H/4g or NPT; face Ra ≤0.4μm for sealing; passivated after machining. Pump-valve wear parts: bore H7; OD/bore concentricity ≤0.005mm; Ra ≤0.4μm; pressure-tested. ASTM B574 material certificate with chemical composition. C-22 (Hastelloy C-22, UNS N06022) available for applications requiring simultaneous oxidising and reducing acid resistance superior even to C-276.

Semiconductor High-Req. Cavity Parts — Inconel 625
Inconel 625 semiconductor process chamber components — gas distribution manifolds, electrode bodies, and structural chamber parts for CVD, ALD, etch, and ion implant equipment operating with reactive process gases (HF, HCl, NF₃, Cl₂, BCl₃). Inconel 625 is specified over SS316L where halogen and hydrofluoric acid process gases would cause pitting corrosion of stainless. Non-magnetic (μr <1.02) — compatible with ion implant magnetic fields. UHV-compatible: outgassing rate after baking at 150°C <10⁻¹¹ Pa·m³/s (measured). Electropolished to Ra ≤0.4μm on all process-gas-contact surfaces — minimum surface area reduces particulate adhesion and outgassing site density. Passivated per semiconductor industry citric acid protocol. All machined surfaces cleaned to semiconductor fab cleanliness protocol — Class 100 packaging. Dimensional inspection CMM report. Material certificate ASTM B443 with chemistry and full mechanical properties.

What Nickel Alloy Parts Require
Beyond Standard Stainless Machining
🐢
5–10× Slower — Work Hardening Control
Nickel alloys work-harden extremely rapidly — cutting speed for Inconel 718 (aged) is 20–30 m/min vs 200–300 m/min for steel 4140. Feeds must be high enough to shear through the work-hardened layer below the tool; rubbing creates rapid tool edge dulling. Cutting parameters are managed per alloy grade and condition — aged 718 requires different parameters from annealed 625. Tooling cost per nickel alloy part is 5–10× higher than equivalent steel.
20–30 m/min IN718High-feed strategy
🔥
70+ Bar Coolant — Ni Alloy Heat Critical
Inconel thermal conductivity ~10 W/m·K (vs 50 W/m·K steel) — heat at tool tip 5× worse than steel. High-pressure coolant 70–100 bar directed at cutting zone essential for tool life and dimensional accuracy. Without high-pressure coolant, thermal expansion of Inconel workpiece during machining can exceed part tolerance on long features.
70–100 barDirectional coolant
🏗
Machine Then Age-Harden — IN718 Correct Sequence
Inconel 718 machined in solution-annealed condition (HRC 32–36), then age-hardened after machining to AMS 5662 properties (1380 MPa UTS). Machining after aging (HRC 40+) is 20–30% slower and dramatically increases tooling cost. Heat treatment distortion after aging is typically ≤0.05mm and is managed by allowance at DFM. We specify and execute the correct sequence — not machining fully aged IN718 bar stock.

Nickel Alloy Grades for Every Extreme Environment
Nickel alloy grade selection is determined by the primary service challenge: temperature, corrosion environment, or both.
MAT / 01
Inconel 625
ASTM B443/B564 · 980°C · Corrosion + moderate HT
Standard corrosion + temperature alloy. Resists seawater, acids, and oxidising environments to 980°C. Machined in annealed condition, no heat treatment required. Default for chemical, marine, vacuum, and semiconductor applications requiring both corrosion resistance and elevated temperature.

Inconel 718
AMS 5662/5663 · 700°C · 1380 MPa aged
The standard structural superalloy for aerospace, turbine, and high-temperature fastener applications. Precipitation-hardened after machining to 1380 MPa UTS — maintains useful strength to 700°C where steels lose yield strength. Machine in annealed condition, age after machining. AMS 5662 material cert with full mechanical test report.

MAT / 03
Hastelloy C-276
ASTM B574/B575 · pH 0–14 · Reducing + oxidising
Broadest chemical resistance of any commercial alloy. Resists both reducing acids (HCl, H₂SO₄) and oxidising acids (HNO₃) simultaneously. Standard for chemical reactor, pump-valve, and process plant parts where SS316L and Inconel 625 fail due to halide or reducing acid corrosion. More expensive and harder to machine than 625.
HCl/H₂SO₄Cl₂ gas
MAT / 04
Hastelloy C-22
UNS N06022 · ASTM B575 · Mixed acid superior
Similar to C-276 with improved resistance to oxidising acids and wet chlorine — for chemical plant where both oxidising and reducing acid environments must be resisted by a single alloy specification. Higher Cr content vs C-276 provides better oxidising acid resistance while Ni-Mo maintains reducing acid resistance.
Mixed acid
MAT / 05
Monel 400
UNS N04400 · 67% Ni 30% Cu · Good machinability
67% Ni, 30% Cu alloy — good seawater and brackish water corrosion resistance; best machinability of common Ni alloys (machinability ~30% of brass but significantly better than Inconel). Used for marine fittings, pump components, and moderate-temperature parts where Inconel is over-specified and SS316L corrosion resistance is insufficient.

625
Grade Advisory — 625 vs C-276
We advise on alloy selection at DFM: Inconel 625 for corrosion + temperature; C-276 for the most aggressive acid environments where 625 is insufficient; C-22 where simultaneous oxidising/reducing acid resistance is required. Not all chemical plant parts need C-276 — over-specifying adds unnecessary cost.
70B
70+ Bar Coolant — Non-Negotiable
High-pressure coolant at 70–100 bar is not an upgrade option for nickel alloy machining — it is the baseline requirement for dimensional accuracy and tool life. We do not machine nickel alloys on flood-coolant machines where temperature control is inadequate.

Întrebări frecvente
Nickel Alloy CNC Parts — Întrebări frecvente
Inconel 625 (ASTM B443/B564): corrosion + temperature to 980°C, annealed. Inconel 718 (AMS 5662): 1380 MPa aged, 700°C strength. Machine in anneal, age after. Hastelloy C-276 (ASTM B574): pH 0–14, HCl/H₂SO₄/Cl₂ resistant. C-22 (ASTM B575): mixed oxidising+reducing acid. Monel 400: marine, best Ni machinability. We advise on grade at DFM — most chemical plant requirements do not need C-276; many can use 625 at lower cost.
(1) Rapid work hardening — feed must cut through hardened layer; rubbing dulls tools instantly. (2) Low thermal conductivity ~10 W/m·K — heat at tool tip 5× worse than steel; 70+ bar coolant essential. (3) High cut strength — Inconel 718 aged HRC 40+ machined at 20–30 m/min vs 200–300 m/min for 4140 steel. Machining time is 10× longer; tooling 5–10× higher. This is why nickel alloy parts cost significantly more than steel — it is unavoidable physics, not supplier margin.
Inconel 625: annealed, no HT. Primary property = rezistența la coroziune (seawater, acids, oxidising environments to 980°C). Limited load capability above 650°C. Use for: chemical plant, marine, vacuum, semiconductor. Inconel 718: machined in anneal, then age-hardened to 1380 MPa after machining. Primary property = high-temperature mechanical strength (maintains 900 MPa yield to 650°C). Use for: turbine components, aerospace, high-temp fasteners. Rule: need corrosion resistance → use 625. Need high-temp strength → use 718.
MOQ: 1 piesă. Lead times: simple turned/milled parts: 10–15 working days. Complex 5-axis parts: 14–21 working days. IN718 with age-hardening: add 5–7 working days for HT. Material costs: nickel alloys are 8–15× higher than SS316L by weight. Machining is 5–10× slower than steel. These costs are unavoidable — nickel alloys are only specified when required. ASTM B443/B574/AMS 5662 material certificates available for all grades.
