Stainless steel
Alloy 800H / 1.4876
Alloy 800H is an Fe-Ni-Cr alloy with Werkstoffnummer 1.4876, EN X10NiCrAlTi32-21. Higher nickel than 310S – intended for high temperature, not for wet chloride like 316L. INDUSTRISTÅL supplies bar and tube with 3.1. 321H when Ti-stabilised 18-8 is sufficient.

Frequently asked questions
- What is Alloy 800H?
- Fe-Ni-Cr 1.4876 for high temperature. Not 321.
- 800H or 310S?
- 310S is stainless 25/20. 800H has more nickel and a different hot strength.
- Do you supply 1.4876?
- Yes, to order. State the form and temperature requirement.
