The welding technology of S690QL material equivalent

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. S690QL material equivalent Heat treatment process refers to the ability to change the microstructure and properties of S690QL material equivalent after heat treatment, including hardenability, hardenability, temper brittleness, etc.

321 stainless steel has excellent high-temperature stress rupture performance and high-temperature creep resistance, stress mechanical properties, are better than 304 stainless steel. Austenitic stainless steel is equivalent to the Chinese grade 0Cr18Ni10Ti. 321 stainless steel is Ni-Cr-Mo austenitic stainless steel, its performance is better than 304. Due to the addition of titanium metal, S690QL material equivalent, 321 stainless steel plate and sheet have better resistance to grain boundary corrosion and high temperature strength.
