SS 304L Stainless Steel Angles
Precision Alloys is a leading manufacturer and exporter of SS 304L stainless steel angles, offering low-carbon, corrosion-resistant profiles that meet ASTM A276, ASME SA276, EN 10088, and DIN 1.4307 standards. Designed for excellent weldability, formability, and clean surface finish, SS 304L angles are widely used in welded structures, pharmaceutical equipment, and architectural frameworks.
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.
