Material description for 1.2738
1.2738 is a high-strength die steel with excellent toughness, wear resistance and processability. 1.2738 steel is often used in the manufacture of high-quality plastic 1.2738, injection molds, die casting molds and extrusion molds.
1.2738 High hardness and strength make it still have excellent cutting performance and deformation resistance at high temperatures, thus improving the service life of 1.2738. 1.2738 specific well divided into C: 0.30 0.40, Si: 0.10-0.40, Mn: 1.30-1.60, Cr: 1.80-2.10, Ni: 0.30 or less, Mo: 0.15 to 0.25. The use of media and use environment will have an impact on 1.2738, and the production process will also have an impact on 1.2738.
1.2738 is widely used in the manufacturing of automotive parts, aviation parts, medical devices, precision instruments, electronic products and other high-precision and high-demand fields. The hardness of 1.2738 is about 28-32HRC, and the hardness after quenching and nitriding heat treatment can reach 38-42HRC. The surface quality of plastic products depends on the surface quality of the mold that produces the product, so the non-metallic inclusions and material segregation contained in 1.2738 affect the polishing properties of steel.
In short, 1.2738 is often used in the manufacturing of medical devices, food processing equipment and chemical equipment and other industrial fields with high requirements for health and corrosion resistance. Toughness is another important performance indicator of 1.2738, in general, the higher the hardness of 1.2738 has a lower toughness.
