|SUS410 / Stainless Steel 410 is a magnetic, martensitic, heat treatable alloy that is 12% straight chromium. It has excellent creep strength and corrosion resistance. Heat treatments may be applied to develop a very wide range of mechanical properties and hardness. It is popularly used for parts operating at high temperatures.|
|SS410 is the basic martensitic stainless steel; like most non-stainless steels it can be hardened by a “quench-and-temper” heat treatment. It contains a minimum of 11.5 per cent chromium, just sufficient to give corrosion resistance properties. It achieves maximum corrosion resistance when it has been hardened and tempered and then polished. SUS410 is a general purpose grade often supplied in the hardened, but still machinable condition, for applications where high strength and moderate heat and corrosion resistance are required.
Martensitic stainless steels are optimised for high hardness, and other properties are to some degree compromised. Fabrication must be by methods that allow for poor weldability and usually the need for a final heat treatment. Corrosion resistance of the martensitic grades is lower than that of the common austenitic grades, and their useful operating temperature range is limited by their loss of ductility at sub-zero temperatures and loss of strength by over-tempering at elevated temperatures.
Is 410 ferritic or martensitic?
Alloy 410S (UNS S41008) is a low carbon, non–hardening modification of Alloy 410 (UNS S41000) the general purpose 12% chromium martensitic stainless steel. The low carbon and a small alloy addition minimize austenite formation at high temperatures which restricts the alloys ability to harden.
What is the difference between 410 and 416 stainless steel?
Type 416 Stainless Steel is a stainless steel which is martensitic and can be hardened by heat treatment to higher strength and hardness levels. … Type 416 is somewhat inferior in corrosion resistance to other 12% chromium stainless steels, such as type 410.
What do you weld 410 stainless steel with?
Grade 410 steels can be welded using all conventional welding techniques, but the materials should pre-heated at 150 to 260 °C followed by post-weld annealing treatment, to mitigate cracking. Grade 410 welding rods are recommended for tempering and post-hardening.
