Q:What is 304L stainless steel?
A:
304L (UNS S30403) is a low-carbon austenitic stainless steel with maximum 0.03% carbon content. It offers excellent weldability and resistance to intergranular corrosion.
Q:What is the difference between 304 and 304L?
A:
304L has lower carbon (max 0.03%) compared to 304 (max 0.08%), making it more resistant to sensitization during welding and reducing the risk of intergranular corrosion.
Q:What aerospace specifications do you comply with for 304L?
A:
We supply 304L stainless steel in accordance with AMS 5511, AMS 5513, AMS 5639, AMS 5647, ASTM A240, and ASTM A666 specifications.
Q:Why is 304L preferred for bracket applications?
A:
304L offers excellent weldability, superior corrosion resistance (especially after welding), good formability, and meets aerospace specifications - making it ideal for brackets in demanding applications.
