9Cr18Mo wholesale manufacturers of stainless steel mold steel 9Cr18Mo 9Cr18Mo quality bearing steel

9Cr18Mo 9Cr18Mo 9Cr18Mo is to produce stainless steel bearing rings and rolling with a high carbon chromium stainless steel. Stainless steel cutting tools used for slicing and cutting machinery tools, surgical blades, high wear equipment parts. Introduction Standard: GB / T 1220-1992 JIS G4311: 1991ASTM A959 2004EN10088-1ISO 4955: 2005 Range (E) Features and application: 9Cr18Mo 9Cr18Mo is to produce stainless steel bearing rings and rolling with a high carbon chromium stainless steel. Stainless steel cutting tools used for slicing and cutting machinery tools, surgical blades, high wear equipment parts. 9Cr18 high carbon martensitic stainless chromium bearing steel. After quenching with high hardness and wear resistance, high temperature, low temperature dimensional stability. 9Cr18Mo characteristics and uses essentially the same 9Cr18 steel, but with a higher hardness after quenching and temper resistance, molybdenum increase the passivation of stainless steel. 9Cr18,9Cr18Mo carbon chromium stainless steel ball Uses: Suitable for the manufacture of bearings in the bearing sea water, river water, nitric acid, steam, and marine and other corrosive media, such as ships, submersible pump parts of the bearing, the oil and chemical machinery, marine instrument bearings. 2 Chemical composition Chemical Composition: Carbon C: 0.90 ~ 1.00 Si Si: ≤0.80 Mn Mn: ≤0.80 sulfur S: ≤0.030 phosphorus P: ≤0.035 chromium Cr: 17.00 ~ 19.00 Ni: to allow contains ≤0.60 Mo Mo: can be added ≤0.75 3 Mechanical Properties Mechanical Properties: Hardness: annealing, ≤255HB; quenching and tempering, ≥55HRC 4 heat heat treatment and microstructure specifications: Heat treatment specifications: 1) annealing, 800 ~ 920 ℃ slow cooling; 2) quenching, 1000 ~ 1050 ℃ oil cooling; 3) tempered, 200 ~ 300 ℃ oil, air cooling. Microstructure: Organizing for the martensitic. Delivery status: generally heat treatment delivery, the treatment types specified in the contract; not indicated, by not heat treatment delivery. 5 features high hardness and wear resistance of medium, when polished, its drawback is relatively large viscosity, and temperature quickly. 6 Use for corrosion resistance (magnetic) cutlery (knife), after the turbine blades hardened steel hardness ratio increased 440A (magnetic), blades, nozzles, valves, board feet, cutlery (scissors). 7 Specifications Product Name Specification / mm Material Stainless steel wire Ф5.5-30 9CR18MO light round stainless steel cold-drawn steel hot-rolled bar Ф3.0-100 9CR18MO Ф14-350 9CR18MO 1-180 9CR18MO stainless steel hot-rolled steel cold-rolled steel 0.1 4.0 * 1220 * 2440 9CR18MO 0.1-180 9CR18MO 8 stainless steel cold-rolled stainless steel adjusters formulas: diameter × diameter × 0.00609 = kg / m, for example: ￠ 50 50 × 50 × 0.00609 = 15.23Kg / m diameter × diameter × 0.00623 = kg / m, for example: ￠ 50 50 × 50 × 0.00623 = 15.575Kg / meter stainless steel profiles, adjusting the formula hexagonal bar edge-to-edge × × 0.0069 = Kg / m square bar side edge width × width × 0.00793 = Kg / m
