Experimental requirements that stainless steel pipes must meet under acidic conditions!

2018-12-27View Original

Thread Content

I’m seeking advice from experts: in acidic environments, stainless steel A312 Gr TP316/316L must meet the requirements of NACE MR 0175/ISO 15156. What specific testing is required? 1. The customer requires metallographic tests. But we purchase seamless steel pipes, and metallographic testing is generally done on welded steel pipes – is it necessary to conduct this test? I’m looking for any documentation regarding the testing requirements specified in NACE MR 0175/ISO 15156 for carbon steel and stainless steel. Thank you!

Metallographic analysis is required to determine the material’s cleanliness and grain size, in order to prevent HIC corrosion
