Description

Product:DIN1.***1, AISI P*0, GB/T 3Cr2Mo, ASSAB **8, JIS PDS*3 tool steel, die steel, plastic steel, flat steel, round steel, square, forged steel, alloy steel, P*0/DIN 1.***1/**8/GB 3cr2mo is a pre hardened high tensile tool steel which offers ready machineability in the hardened and tempered condition, therefore does not always require further heat treatment. This eliminates the risks, cost, and waiting time of heat treatment and avoids the associated possibility of distortion or even cracking. Subsequent Plastic Tool Steel P*0/DIN 1.***1/**8/GB 3cr2mo component modifications can easily be carried out. Similar Grades:DIN1.***1, AISI P*0, GB/T 3Cr2Mo, ASSAB **8, JIS PDS*3 Chemical Composition C :0.*8~0.*0 Si :0.*0~0.*0 Mn :0.*0~1.*0 Cr :1.*0~2.*0 Mo:0.*0~0.*5 P : Max 0.**0 S : Max 0.**0 Features: P*0, American AISI standard pre-hardened plastic mold steel, good machining performance, excellent polishing performance, a certain toughness, can be carburized, surface hardness is up to *5HRC after carburizing quenching, with higher hot hardness and wear resistance.
