Plastic mold steel is the corrosion-resisting-steel, easy to machining, polishing mold steel material.   Main Steel Grade have ASTM AISI/SAE “P” Serise. Typical Steel material P20 tool steel. Different country and company have different Name and standard. some steel grade is equivalent. Like AISI P20 VS DIN 1.2311, P20+Ni VS 718, S136 VS 1.2083 VS M310 Steel.

P20 Plastic Mold Steel | 1.2311 | 3Cr2Mo| 35CrMo2 Tool Steel

ASTM A681, DIN 17350, YB/T 094, EN ISO 4957

AISI/ SAE P20 Steel is a typical Plastic products tool steel, which usually used in applicable to the front of the TV shell, telephone, water machine, vacuum cleaner and other plastic mold and die set. Thermoplastic plastic injection mould, extrusion die, Etc.

P20 S Plastic Mold steel | 1.2312 | SKT3 | 40CMD8+S Tool Steel

ASTM A681, DIN 17350, YB/T 094, EN ISO 4957, NF A35-590

AISI/ SAE P20 S Steel is add Sulphur base on P20 Steel, which usually used in the mold manufacture of the front of the TV shell, telephone, water machine, vacuum cleaner and other plastic mold and die set. Thermoplastic plastic injection mould, extrusion die, Etc.

S136 Plastic Mold Steel | AISI 420 ESR | 1.2083 | M310 tool steel

ASTM A681, DIN 17350, YB/T 094, EN ISO 4957

S136 is the ASSAB Plastic Mold Steel, which usually used in the high quality, high mirror require plastic products mold. Thermoplastic plastic injection mould, extrusion die; Overloading mold main components; The bumper mould for car.

ASSAB 718 plastic mold steel | P20+Ni | 3Cr2NiMo | 1.2738 | M238

ASTM A681, DIN 17350, YB/T 094, EN ISO 4957

ASSAB 718 Steel is a typical Plastic products mold tool steel, it is equivalent with P20+Ni/ 1.2738/M238/3Cr2NiMo. It have better Heat treatment Hardness and hardenability than P20 steel.  718 Steel used in large size plastic products mold manufacture, so that ensure the surface hardness and centre hardness all is well.
