SUS 410 stainless steel: a powerful assistant for mechanical manufacturing
SUS 410 is a martensitic stainless steel and is a grade in the Japanese Industrial Standard (JIS). It is based on iron, with a chromium content of about 11.5% - 13.5% and a relatively high carbon content of 0.08% - 0.15%. The higher carbon gives it good strength and hardness, while the chromium element gives the steel a certain degree of corrosion resistance.
SUS 410 has excellent strength and hardness. After heat treatment, the tensile strength can reach 520 - 750MPa, the yield strength is 345 - 520MPa, the Brinell hardness is about 170 - 200, and the wear resistance is good. However, compared with austenitic stainless steel, its corrosion resistance is slightly weaker. It performs well in ordinary atmospheric environments, but it is easy to rust in strong acid, alkali or high salt environments. It has heat treatment strengthening characteristics, and the performance can be optimized by quenching and tempering.
In terms of size specifications, the thickness of the plate is generally 0.5-100mm, the width is 600-2000mm; the diameter of the round steel is 3-200mm; there are also various specifications such as pipes and wires to meet different processing needs.
It has a wide range of applications. It is often used to make nuts, bolts, shaft parts, etc. in mechanical manufacturing; in the tool industry, it is a common material for kitchen knives and hand knives; in the manufacture of valves and pump components, valve cores, pump shafts, etc. are also often made of SUS 410, which relies on good mechanical properties to ensure stable operation of the equipment.
