Hastelloy N Scrap Buyer and Seller
Hastelloy N sits between the B-type alloys, with about 28% molybdenum and almost no chromium, and the C-type alloys, with 15 to 22% chromium. Mixed into either it changes the melt, so Mipra Steel lots it separately.
Sell Hastelloy N Scrap
Tell us the form (sheet, plate, bar, pipe, turnings), weight, location and any certificates naming AMS 5607, AMS 5771 or ASTM B 434. A reading with molybdenum near 16% and chromium near 7% confirms N. We review incoming enquiries and respond with relevant next steps.
Mipra Steel buys Hastelloy N scrap from sellers across India, with much of what we handle coming from the south: Bengaluru, Hyderabad, Chennai, Coimbatore and Visakhapatnam. Our head office is in Khetwadi, Mumbai.
What Is Hastelloy N?
Haynes International describes Hastelloy N as having good oxidation resistance to hot fluoride salts in the 1300 to 1600°F (about 700 to 870°C) range, and expects it to be most useful where fluorides are present at high temperature. It is approved for ASME Section VIII pressure vessels up to 1300°F (704°C).
Because its uses are specialised, N is seldom offered in volume. When it does appear, it comes as sheet, plate and bar offcuts, pipe and tube, or parts from high-temperature process equipment. Lots usually carry certificates, which helps, since few people recognise the alloy by name.
N is listed with the Hastelloy alloys. HASTELLOY is a trademark of Haynes International, used here only to identify material.
