OTAI SPECIAL STEEL is ASTM P20 Tool Steel stockholders and suppliers from china. we have more?our 16 years experience in special steel supply.

ASTM P20 ?Steel is a good quality plastic tool?steel, P20 steel belong to the high quality medium carbon,Pre-hardness(28~34HRc) plastic mould steel. It no need further heat treatment. so you don’t have any?worry about distortion or cracking.

P20 tool steel?properties is very simliar with GB?3Cr2Mo, ?IOS?35CrMo2, DIN 1.2311 steel. At?most work?environment, ?P20 steel is?equivalent with 1.2311, 35CrMo2, 3Cr2Mo mold steel.

Form of Supply

ASTM P20 tool?steel, we can supply the p20 steel round bar, ?steel flat bar, steel plate, hexagonal steel bar and steel square block. P20 steel Round bar?can be sawn to your required lengths as one offs or multiple cut pieces. Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar can be supplied, providing a quality precision finished bar to tight tolerances.


Applications

ASTM P20 Tool steel is a?American plastic Die steel material, the steel by “super clean” production process, pre hardened, showing the height of micro pure and excellent homogeneous structure, excellent polishing and light etching engraving. After heat treatment, processing and polishing performance is good, can be carried out, and can be processed, suitable for the surface treatment of chrome, material hardness, good toughness, good mechanical processing performance. Gold microstructure is martensite and bainite structure.Main be?applied to?in plastic steel mold. like car?injection moulding, PVC?plastic injection molding.
