What are stainless steels:
Iron-base alloys containing different sufficient CHROMIUM to form a stable passive film on the surface.
10.5% is the qualifying concentration of Cr for an alloy to be called Stainless Steel.
What makes stainless steel “stainless”:
With sufficient chromium(>10.5%), the steel is able to form a protective film on the surface (passivate) in aqueous environments.
Properties of Martensitic (410L):
- High strength, hardness & wear resistance
- Heat treatable
- Low corrosion resistance
- Magnetic
- Marginal high temperature strength & oxidation resistance
- Low ductility
- Low cost material offering good wear resistance
- Alloying elements: Cr(C, N)
Properties of ferritic:
- Low to moderate corrosion resistance
- Moderate strength & ductility
- Magnetic, not heat treatable
- Marginal high temp strength & oxidation resistance
- Higher thermal conductivity
- Lower coefficient of thermal expansion
- Low-cost option with functional corrosion resistance
- Alloying elements: Cr(Mo, Nb)
Stainless Steel Powder 410/420/430 Application suggest:
Stainless steel sand; thermal spraying; metal blasting; magnetic materials, carbide, diamond tools and additives
