Features Applications: 440C has all stainless steel, heat-resistant steel in the highest hardness. A nozzle, bearing .440F: to improve the performance of free-cutting steel 440C steel. For automatic lathes. Martensitic stainless steel and alloy steel, as has the realization hardened by quenching characteristics, it can be used to obtain a wide range of different mechanical properties by selecting grade and heat treatment conditions. 440C stainless steel carbon content of C-1.2% this rust resistant steel Yes, it is currently used in high-grade quality stainless steel batch tool on the market, its strength and sharpness resistance even at ATS-34, the chromium content up to 16-18% , is the second most commonly used stainless steel (after ATS-34), is the first to be accepted Cutlery stainless steel, and has been very popular, especially in the minus processes have been developed, such a process to enhance the toughness of steel degrees. Characteristics: high hardness and good wear resistance, when polished, its drawback is that relatively large viscosity, and the temperature quickly, but it is more likely than any steel polished, hand sawing material is also much easier. 440C annealing temperature is low, the hardness usually reaches HRC56-58, corrosion resistance and toughness are strong, now more widely used in high-quality hand-made knives and tool manufacturing plant. Purpose: 440C Assab special steel after quenching high hardness, good corrosion resistance (magnetic) cutlery (knife), a turbine blade after quenching, hardness increased more than 440 steel (magnetic) blades, nozzles, valves, board feet , cutlery (scissors). 2 Chemical composition Chemical Composition: Carbon C: 1.10 Si Si: ≤1.00 Mn Mn: ≤1.00 sulfur S: ≤0.030 phosphorus P: ≤0.035 chromium Cr: 16.00 ~ 18.00 Ni: to allow containing ≤0.60 Mo Mo: can be added ≤0.75 3 Mechanical properties Mechanical properties: Hardness: annealing, ≤269HB; quenching and tempering, ≥58HV Mechanical properties: stress (250 N / mm2) Tensile strength (560 N / mm2) EL (18%) HB (250) 4 Heat Treatment Process heat treatment and microstructure specifications: Heat treatment specifications: 1) annealing, 800 ~ 920 ℃ slow cooling; 2) quenching, 1010 ~ 1070 ℃ oil cooling; 3) tempering, 100 ~ 180 ℃ rapid cooling.
