L6 Hardware Tool Steel Bar
L6 steel is the United States is not deformed wear-resistant steel, alloy steel, heat-resistant wear-resistant steel, good impact resistance, with appropriate hardness and good toughness. L6 plastic mold commonly used steel, better overall mechanical properties, high hardenability, can make larger cross-sectional steel to obtain more uniform hardness. L6 steel has a good throwing optical properties, made of the mold surface roughness value of 90 low. The steel used to make the mold generally first quenched and tempered, the hardness of 52 ~ 62HRC (ie, pre-hardened), the mold can be used directly after cold working, so that not only ensures the mold performance, but also to avoid heat treatment caused by the mold Deformation.
