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 Austenitic(304,304L): (L means C﹤ 0.03%)
Excellent resistance to corrosion
High toughness and good buctility
Moderate strength, hardenable by cold work
High resistance to oxidation at elevated temperature
Low thermal conductivity
High coefficient of thermal expansion
Non-magnetic Not heat treatable
Alloying elements: Cr, Ni, (Mo) min 9%
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 304 304L is a kind of common stainless steel, it is widely used to make for a good comprehensive performance, corrosion resistance and formability of equipment and parts. PM, Sintering, MIM, such processes are mainly used watches, jewelry, cutlery products, Stainless steel protective film and a variety of stainless steel structures.
Why use stainless steel:
- Corrosion resistance
- Oxidation resistance
- Elevated temperature mechanical strength
- Room temp mechanical strength, toughness
- Low-cost wear resistant material (with 410)
- Magnetic behavior with ferritic
