SS 316 / SS 316L Stainless Steel Angles Manufacturer
What Are SS 316 & SS 316L Stainless Steel Angles?
SS 316 stainless steel angles are molybdenum-bearing austenitic stainless profiles that provide excellent resistance to pitting, crevice corrosion, and chloride attack, particularly in marine and chemical environments.
SS 316L is the low-carbon variant of SS 316, offering the same corrosion resistance with enhanced weldability and reduced risk of intergranular corrosion post-welding.
Both grades are available in equal and unequal leg angles, and are ideal for structural reinforcement, bracing, frames, and supports in corrosive or high-purity applications.
