What is 302 Stainless Steel?
Grade 302 stainless steel is an austenitic chromium-nickel stainless steel known for:
- High tensile strength
- Excellent toughness
- Good corrosion resistance
- Superior cold workability
- Non-magnetic properties in annealed condition
The UNS designation for this material is UNS S30200 pipes, and it closely resembles 304 stainless steel, with slightly higher carbon content, which enhances strength.
Because of its strength and resistance to oxidation, 302 Stainless Steel Pipe is commonly used in structural and high-pressure environments.
