SUS410 (410)
SUS410 Martensitic Stainless Steel
AISI 410Characteristics of SUS410:
SUS410 is a kind of martensitic stainless steel. It can achieve relatively high strength, toughness and corrosion resistance after appropriate heat treatment. Its machinability is excellent. It is mainly used as steel for general use, cutting steel and so on. It is not suitable for harsh corrosive environment.Chemical composition of SUS410 (%):

Heat treatment of SUS410:
1. Annealing: Annealing temperature is 800~900℃. Slow cooling.
2. Quenching: Quenching temperature is 950~1000℃. Oil cooling.
3. Tempering: Tempering temperature is 700~750℃. Rapid cooling.Corrosion resistance of SUS410:
SUS410 has a certain corrosion resistance in dilute nitric acid or weak organic acid at room temperature.Mechanical properties of SUS410:

Weldability of SUS410:
All kinds of welding techniques can be applied in the welding of SUS410. If the welds need machining, annealing should be carried out properly.Applications of SUS410:
1. SUS410 is greatly recommended to manufacture the components requiring relatively high toughness and corrosion resistance. In addition, the components should bear a certain impact load.
2. SUS410 can be used as a heat-resistant steel as well to manufacture the parts which are oxidation resistant below 800℃.
3. Cutting tools and western tableware (like spoon, fork, knife, etc.)
4. Turbine blades
5. Hydraulic valvesFor further information on selection, application, heat treatment and inventory, please contact us kindly. Your inquiries about our martensitic stainless steel and other stainless steel are highly appreciated.
