Buy A2 A2 steel price chemical composition of tool steel materials, steel

A2 tool steel hardness after heat treatment than SKD11, high temperature (500-520 ℃) ??after tempering up to 60-62HRC hardness, in intensity over SKD11. 2, tenacity is SKD11 twice. The toughness of A2 tool steel mold steel in the cold is more prominent, therefore, with the A2 steel die and the few cracks crack, greatly improving the service life. 3, after the wire cutting residual stress, high temperature tempering reduces the residual stress. Therefore, the requirements of large molds and precision of the mold line of the crack after cutting and deformation to be curtailed. 4, cutting more than SKD11. A2 tool steel cutting better than SDK11. Therefore, the use of A2 tool steel can increase tool life and reduce the manufacturing processes. Uses: red plant mold / cold mold / cold-drawing mold / molding roll / punch / wire cutting, precision punching and stamping dies for various purposes / plastic deformation of materials difficult to machine tools. Practical features: (1) is cutting, is good grinding. By cutting, abrasive are better than SKD11 was excellent, so the processing tool life longer processing time than the number of provinces. (2) heat treatment on the advantages of high-hardened than the SKD11, so we can improve the hardness of the vacuum heat treatment, lack of defects. (3) the advantages of on-line cutting through the high-temperature tempering reduces residual stress and eliminating residual austenite, to prevent the wire cutting cracks, deformation problems. (4) in the surface hardening treatment of the advantages of surface hardening the surface hardness than SKD11 high, mold can improve performance. (5) repair welding work on the merits because warm and hot temperatures than after SKD11 low, so relatively easy to repair welding operations. Features: Common cold die steel, high hardness, high toughness.
