DIN 1.2083 steel is the most popular one for the type of stainless plastic mold steel. It is a good material, especially for the high-level mirror plastic mold. DIN 1.2083 plastic mold steel has great wear resistance with high Cr. The content of Cr is more than 15%. And it has good polishing performance properties and machinable properties. After quenching, it will get better wear resistance, will be a great material for mold with acid plastic and high polishing property requirements. And people usually called it as 2083 steel.
2083 steel has good wear resistance and corrosion resistance. And it also has low deformation rate and high surface precision. Due to the good corrosion resistance, the cost of repair is quite low. It usually is used to make the PVC mold and other hot runner plastic molds. Such as the mold of disposable dishware.
