The Effect of Cold-rolled Crafts on Super Critical Seamless Steel Pipe TP310HCBN Outer Surface Cracking
This article introduces the status quo of supercritical boiler tube tubes,and studies the effects of cold-rolled deformation and thermal treatment temperature on the surface of the seamless steel pipe surface of the Octoberian stainless steel for TP310HCBN.The semi-grade solid solution temperature is between 1 200～1 270 ℃.With the temperature rises,the grains are getting thicker and larger,the grain size is 2～7,and the outer surface has a circular horizontal cracking phenomenon and cannot be eliminated.After the adjustment process is adjusted,after the adjustment process The semi-finished product is solid-soluble between 1 240～1 250℃,and the surface of the steel tube is eliminated when the deformation is 30％～40％.
