Next, this time Hangzhou precision parts processing manufacturers to introduce the features and applications of the other parts of the mechanical processing species to you:
1, SKD11— — ductile chromium steel. The production of Japanese Hitachi plant. The casting structure in the steel was improved and the grain was refined. The toughness and wear resistance of Cr12mov were improved. The service life of the die was prolonged..2, D2— — high carbon and high chromium cold steel, produced in the United States. It has high hardenability, hardenability, wear resistance, good oxidation resistance at high temperature, good corrosion resistance and low heat treatment after quenching and polishing. It is appropriate to make various cold working dies with high precision and long life, such as drawing die, cold extrusion die, cold shearing knife and so on. . 3, SKD11 (SLD) — — non deformation toughness high chromium steel. Japanese Hitachi production. Because of the increase of MO and V content in steel, the cast microstructure in steel is improved, grain refinement is refined and the morphology of carbide is improved. Therefore, the strength and toughness of the steel (bending strength, deflection, impact toughness, etc.) are higher than that of SKD1, D2, and wear resistance. High resistance to fire. Practice has proved that the life of this steel die is higher than that of Cr12mov. The mold with high requirements is often manufactured, such as drawing die, mold of impacting grinding wheel, etc. 4, DC53&mdash, &mdash, high toughness and high chromium steel, Japanese Datong strain production. The hardness of heat treatment is higher than SKD11. high temperature (520-530) high hardness of 62-63HRC after tempering. In strength and wear resistance, DC53 more than SKD11. toughness is two times the toughness of SKD11, and the toughness of.DC53 is seldom cracked and cracked. Life. The residual stress is small. The residual stress is reduced after high temperature. The cracks and deformation after wire cutting are suppressed. The cutting and abrasive properties are more than SKD11. for precision stamping die, cold forging, deep drawing, and so on..5, SKH-9— — wear resistance and toughness of general high speed steel. Japan Hitachi plant type production. Used for cold forging die, cutting machine, drill bit, reamer, punch and so on.
