 P20 Steel Introduction 

P20,P20 Steel, Mould Steel

P20 steel , a 4130, 4135 modified material, has long been the steel of choice for pre-hardened mold steels. P20 is classified as a chrome-moly alloy, with a carbon content of approximately 0.30 to 0.40. Over time, many variations on basic P20 chemistry have been introduced to the marketplace. Each modification can have an effect on the various processes used in the fabrication of a mold.
P20 Steel Delivery state
P20 Steel Material should be delivered at AR(As Hot Rolled), N(Normalized), T(Tempered), Q(Quenched), TMCP, Q+T(Quenched and Tempered), UT(Ultrasonic Test:ASTM A435,ASTM A578-C/B/A,EN10160-S0E1,S1E2,S2E3,S3E4), Impact Test, PWHT(Post Weld Heat Treatment), HIC, Z Test(Z15, Z25, Z35).
P20 Steel Application
P20 steel plate/sheet is used for the production of various kinds of plastic molds, such as High mirror surface mold, Mold base and so on.
