P20 steel round bar sheet plate has many excellent properties. In the pre-hardened status, the mold can be processed without any heat treatment. Which cut down the running period and improves efficiency. After it has been processed through the forged, 1.2311 steel becomes dense. Then it can pass 100% ultrasonic test. And after the test, there will be no pores left and no defect. And it also is called DIN 1.2311 and SCM4 steel. P20 tool steel chemical composition and more information as below
