1What is the difference between Hastelloy and Inconel?
Hastelloy (nickel-chromium-molybdenum) excels in corrosion resistance, especially in reducing environments. Inconel (nickel-chromium-iron) excels in high-temperature strength and oxidation resistance. Choose Hastelloy for chemical processing; Inconel for high-temperature applications above 600°C.
2How much does Hastelloy C276 cost per kg?
As of May 2026, Hastelloy C276 costs $42-48/kg for plate, $45-52/kg for sheet, and $55-70/kg for pipe. Prices vary by thickness, quantity, and market conditions. Request a quote for exact pricing on your specification.
3What is the minimum order quantity for nickel alloys?
Most suppliers require 100-500kg minimum. FindSteel offers no minimum order on stock items — you can order as little as 1 piece from our spot inventory. Custom production orders start at 100kg.
4What certifications should nickel alloy products have?
Essential: Mill Test Certificate (EN 10204 3.1), material test report, and chemical composition analysis. For critical applications: also request mechanical properties test, intergranular corrosion test (ASTM A262), and PMI (Positive Material Identification).
5How long does nickel alloy delivery take?
From stock: 3-5 business days worldwide. Custom production: 4-8 weeks depending on specification and quantity. FindSteel maintains 500+ tons of nickel alloy stock for fastest delivery.
6Can Hastelloy C276 be welded?
Yes, C276 has excellent weldability using GTAW (TIG) or GMAW (MIG) processes. Use ERNiCrMo-4 filler metal. No post-weld heat treatment required. Avoid preheating unless base metal is below 10°C.
7What is the difference between Inconel 625 and 718?
Inconel 625 is a solid-solution strengthened alloy with excellent corrosion resistance. Inconel 718 is precipitation-hardened for superior mechanical strength (yield strength 1036 MPa vs 414 MPa). Choose 625 for corrosion; 718 for strength.
8Which nickel alloy is best for seawater?
For seawater service: Hastelloy C276 or C22 for critical components; Inconel 625 for structural parts; Monel 400 for pump shafts and valves. Duplex 2205 is a cost-effective alternative for less critical applications at roughly 1/3 the cost.
9What is the lead time for custom nickel alloy sizes?
Custom sizes from mills: 6-12 weeks. Custom cutting from stock: 1-3 days. FindSteel offers precision cutting (plasma, waterjet, laser) from our stock with 24-hour turnaround.
10How to verify authentic Hastelloy C276?
1) Request MTC (Mill Test Certificate) per EN 10204 3.1. 2) Perform PMI on-site. 3) Cross-check heat number with mill records. 4) Verify chemical composition matches UNS N10276 specification. 5) Check for proper packaging and marking per ASTM standards.
11What is the difference between Duplex 2205 and 316L?
Duplex 2205 has 2x the yield strength (450 MPa vs 205 MPa) and superior pitting resistance (PREN 35 vs 24) compared to 316L. 2205 costs 30-40% more but lasts 2-3x longer in aggressive environments. See our detailed comparison.
12Does China produce quality nickel alloys?
Yes. Leading Chinese mills (Baosteel, TISCO, AT&M) produce nickel alloys to international standards (ASTM, ASME, EN). Key is proper mill selection and certification verification. FindSteel only sources from qualified mills with full MTC documentation.
13What is Monel 400 used for?
Monel 400 (UNS N04400) is primarily used for pump shafts, valve stems, and marine engineering components due to its excellent resistance to seawater and hydrofluoric acid. It offers good strength at sub-zero temperatures and is readily weldable.
14Can I get nickel alloy with expedited shipping?
Yes. FindSteel offers same-day dispatch on stock items for urgent orders. Air freight available worldwide (3-5 days to most destinations). Emergency orders can be processed within 4 hours of confirmation.
15What is the shelf life of nickel alloy stock?
Nickel alloys have no shelf life when stored properly (dry, covered storage). Unlike carbon steel, nickel alloys do not rust or degrade over time. Surface oxidation may occur but does not affect material properties and is easily removed.
