SS 304L Stainless Steel Angles Manufacturer
What are SS 304L Stainless Steel Angles?
SS 304L stainless steel angles are low-carbon austenitic stainless steel structural profiles offering the same chromium-nickel composition as SS 304, but with a reduced carbon content of 0.03% max. This prevents carbide precipitation during welding, making them ideal for welded supports, cleanroom structures, and industrial assemblies that require non-corrosive performance without post-weld heat treatment.
