Characteristics of 410 SS Material
BEBON is has stock of 410 SS plates, sheets and coils in stock. 410 material is a basic straight chromium high hardenability martensitic stainless steel. Below is detail of 410 SS material characteristics.
410 martensitic stainless steel plates and sheets are generally supplied hardened and tempered in the tensile range 700 - 850 Mpa (condition R) Brinell range 201 - 255. 410 material has good strength and fairly good corrosion resistance. It is characterized by good corrosion resistance in mild atmospheric industrial and domestic environments coupled with good strength and excellent toughness in the hardened and tempered condition. Due to its excellent hardenability, 410 SS is capable of being through hardened to over Rc40 depending upon carbon content and section size. Small sections can be air cooled and larger sections oil quenched for maximum through hardness. Pre hardened and tempered 410 will also respond readily to nitriding achieving a typical surface hardness of over Rc65. The nitriding process however reduces the corrosion resistance and is therefore not generally recommended except for critical applications where the benefit outweighs all other considerations.
Corrosion Resistance of 410 SS: 410 martensitic stainless steel has better corrosion resistance than 416 grade, but lower than 431 grade. Also lower than most of the 400 series ferritic stainless steels, and all of the 300 series austenitic stainless steels.NB. It has optimum corrosion resistance in the hardened and tempered condition and is not therefore recommended for use in the annealed condition. It is most important that oxygen is always allowed to circulate freely on all stainless steel surfaces to ensure that a chrome oxide film is always present to protect it. If this is not the case, rusting will occur as with other types of non stainless steels.For optimum corrosion resistance surfaces must be free of scale and foreign particles.
410 SS plates and bars are used for parts requiring a combination of good strength and toughness, plus reasonable corrosion resistance. Typical applications are: Bolts, Bushings, Fasteners, Gas Turbine Parts, Mine Equipment, Pump Parts, Petrochemical Equipment, Steam Turbine Parts, Studs, Valve Parts etc.
