25Cr-35Ni-Nb+MA: Haiyou, could you explain what the seed material is, and what exactly is MA?

Reply #22015-12-30

I searched on Baidu. . This material is a high-chromium-nickel alloy. . It is used to withstand temperatures of over 1,000 degrees, and is applied in things like ethylene cracking furnaces. . This appears to be a special material; no **or industry standards were found. . It is estimated to be a corporate standard. It is recommended to look for standards/technical specifications based on the materials. . . Only then did I understand what that +MA meant.

Well, thank you. It is indeed the material for the furnace tubes in the pyrolyzer; it’s just that I’m not sure what this element means

This is a heat-resistant alloy steel, where MA stands for Micro Alloy, meaning micro-alloying

The “MA” mentioned upstairs is the English abbreviation for trace elements.
