| Detailed description | ||
|
SUS440C steel is martensitic stainless steel, carbon content is higher than 3cr13 steel, so the strength and hardness is higher than 3cr13 steel; other properties are similar to 3cr13 steel; but poor weldability. Usually not used for welding materials · Used for manufacturing surgical tools ·SUS440C Stainless steel imported from Japan is used for manufacturing bearing parts that work in corrosive environments and strong oxidation without lubrication. The steel also has good dimensional stability at high temperature, which can be used to manufacture corrosion-resistant high-temperature bearings and tools at temperatures not exceeding 250 ° C Chemical composition: C: 0.95 to 1.20 Si: 1.00 Mn: 1.00 P: 0.040 S: 0.030 Cr: 16.0 to 18.0 Mo: 0.75 Hardness HRC: 58 ~ 62 Mechanical property Hardness: Annealed,≤269HB; Quench and temper,≥55HRC Use: 440C special steel after quenching high hardness, good corrosion resistance (magnetic) tableware (knife), turbine blades after quenching, than 440 steel hardness increased (magnetic) blade, nozzle, valve, plate rulers, tableware (scissors). Characteristics: High hardness and good wear resistance, when grinding, its disadvantage is that the viscosity is relatively large, and the temperature is fast, but it is easier to grind than any carbon steel, and it is much easier to cut with a hand saw. The annealing temperature of 440C is very low, the hardness usually reaches HRC56-58, the corrosion resistance and toughness are very strong, and it is more widely used in hand-made knives and high-quality factory tools. Characteristic application: 440C has the highest hardness of all stainless and heat-resistant steels. Used for nozzles and bearings.440F: It is a steel that improves the cutting performance of 440C steel. For automatic lathes. Martensitic stainless steel and ordinary alloy steel have the same hardening characteristics, so a wide range of different mechanical properties can be obtained by choosing grades and heat treatment conditions.
