P20 tool steel -What are the P20 mold steel’s mechanical properties

With over 20 years’ pre-sales and after-sales special steel, Otai helps distributors and end-users to avoid all possible swindle and cheat. Our steel materials meet DIN / ASTM / EN / JIS etc different international standards. P20 tool steel is a mold material for plastic injection, it belongs to the high-quality medium carbon.

P20 tool steel is a mold material for plastic injection, it belongs to the high-quality medium carbon.

P20 Tool steel is German Die steel, 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 are good, can be carried out, and can be processed, suitable for the surface treatment of chrome, material hardness even (to 400mm thick), good toughness, good mechanical processing performance. The gold microstructure is martensite and bainite structure.

Main be applied to in zinc, aluminum, magnesium, and its alloy die-casting mold; Hot-pressing mold, all kinds of a hot forging die; Metal extrusion dies, die set.

Customer’s story

We would like to share a real case of our customer with you. Ashraf from UAE sent us an inquiry for P20 steel plates. As time is tight, he needs to receive the goods within 45 days. That’s no problem for us because we keep a daily inventory of 1000 tons. After the customer placed his order, we have prepared his P20 steel plates to ready the next day. We also assisted the customer to find the fastest delivery, and the goods were delivered to the customer in 45 days.

8 consecutive years no quality event complain, over 80% repeat order rate. Otai undertakes every order to end and solve customer’s problems without any hesitation on responsibility. When customized special steel is hard to get, Otai settles satisfactorily completely.
