Normal alloy flange welding is to temper, to ensure the quality of the time, so why do alloy welding flange need to temper?

During tempering, we the temperature of the alloy welding flanges are to improve the performance and alloy elements in the process of tempering to delay the decomposition of martensite and retained austenite transformation (that is, the higher temperature to decomposition and transformation), improve the recrystallization temperature of ferrite, set carbide hard to gather up, thereby improving steel to temper softening resistance, which improves the tempering stability of steel.Of course, in the improvement of alloy welding flange, our real alloy welding flange to improve each element is to improve, so as to be sure to ensure that the alloy welding flange tempering performance.
