What does \"urea-grade stainless steel pipe\" mean? Have any chemical companies purchased this type of stainless steel pipe? Please let me know if there is any, thank you! Has anyone used this type of stainless steel seamless tube, 316Lmod? Is it available in the domestic market?
The last edit to this post was made by ds66616 on 2019-1-11 at 12:27. Features of 724L (316LMod): It is a stainless steel developed for urea production based on 316L, with additional restrictions on the minimum contents of Cr, Ni, and Mo； The goal is to achieve a fully austenitic structure in the stainless steel after the final heat treatment, with a ferrite content of no more than 0.6%; meanwhile, requirements are specified for tests on intergranular corrosion tendency and selective corrosion. This material is specifically designed for use in the urea industry. Therefore, it is referred to as urea and 316L stainless steel. Both urea and stainless steel require the Hydride Test and the selective corrosion test.
