Credibility ,For stainless steel flange, the three elements of solid solution treatment temperature, holding time and cooling rate. Solid solution temperature is mainly determined according to chemical composition. Generally speaking, variety and high content of alloy elements brand, to increase solid solution temperature. Especially manganese, molybdenum, nickel, high content of silicon steel, only to improve the solid solution temperature, make it dissolves, to achieve a softening effect. But stabilized steel, such as 1 cr18ni9ti, solid solution at high temperature stabilization element of carbide dissolves in austenite, in the subsequent cooling in the grain boundary precipitates in Cr23C6 form, caused by intergranular corrosion. For the stabilizing element of carbide (TiC and NbC) decomposition, solid solution, generally USES the lower solid solution temperature.
