DIN 1.2312 steel is a high quality plastic mold steel material. Steel 1.2312 is material produced by add about 0.08% sulphur on material 1.2311. The S element improves free cutting ability of 1.2311 steel. DIN 2312 material is usually delivered in pre-hardness condition and hardness 28~34HRC.
Product Description
ASTM P20+S steel is equivalent to DIN 1.2312 material. Generally, 40CrMnMoS8-6/1.2312 and P20+S mold steel will have the same properties for final application.
