Product Name: 3Cr2Mo
Product Model: Plastic Mold Steel 3Cr2Mo
3Cr2Mo is the most widely used international plastic mold steel, the use of the standard GB / T 1299-1985, is the introduction of the United States P20 carbon Cr-Mo plastic mold steel. Suitable width="100%" border="0" cellspacing="0" cellpadding="0" class="table" for the production of plastic mold and die-casting low-melting metal mold material.
3Cr2Mo has good machinability and mirror grinding performance. Its comprehensive mechanical properties, high hardenability, can make a larger cross-section of the steel to teach more uniform hardness, and has a good polishing performance, mold surface finish high. When the mold is made of the steel, the tempering treatment is usually carried out at a hardness of HRC28 to 35 (i.e., pre-hardening), and then directly processed by the cold working machine into a mold. In this way, that is to ensure the use of mold performance, but also to avoid heat caused by deformation of the mold.
