SUS440C the steel is martensitic stainless steel, carbon steel than 3cr13 high, strength, hardness than 3cr13 steel high performance with other similar 3cr13 steel, but welding is poor, usually no welding. For the manufacture of surgical instruments. SUS440C Japan imports of stainless steel in a corrosive environment for the manufacture of strong oxidizing and non-lubricated bearings working parts. The steel have good high temperature dimensional stability, high temperature bearings can create corrosion and temperature does not exceed 250 ℃ tool.
440C: C-1.2% carbon steel rust this is very good, is currently used in high-volume high-quality stainless steel knives on the market, its strength and sharpness even in the ATS-34, up to 16-18% chromium content , is the second most commonly used stainless (ATS-34), Cutler is the first to be accepted by stainless steel, and has been very popular, especially in the minus processes have been developed, this kind of treatment to strengthen the resilience of steel degree.
Features:
High hardness and good wear resistance, in the polished, its drawback is that viscosity is relatively large, and the temperature quickly, but it is more likely than any steel polished, hand-sawn material is also much easier. 440C annealing temperature is low, hardness usually reach HRC56-58, corrosion resistance and toughness are very strong, are more widely used in high-quality hand-made knife and tool manufacturing plant.
Use:
440C ASSAB special steel after quenching, high hardness, good corrosion resistance (magnetic) cutlery (knife), turbine blades, after quenching, the hardness increased more than 440 steel (magnetic) blades, nozzles, valves, board feet, cutlery (scissors).
Mechanical properties:
Stress (250 N/mm2) tensile strength (560 N/mm2) EL (18%) HB (250)
Chemical composition:
C: 0.95 ~ 1.20, Si: 1.00, Mn: 1.00, P: 0.040, S: 0.030, Cr: 16.0 ~ 18.0, Mo: 0.75, hardness HRC: 58 ~ 62
Features applications:
440C has all stainless steel, heat-resistant steel in the highest hardness. For the nozzle, bearing .440 F: 440C steel is to improve the performance of the steel-cutting. For automatic lathes. Martensitic stainless steel and ordinary steel as a hardening by quenching characteristics to achieve, so by selecting the grade and heat treatment conditions to obtain a wide range of different mechanical properties.
