316/316L Stainless Steel Elbow

Grade: 316/316L

Elbow types:

90° Long Radius, 90° Short Radius, 45° Elbow, 180° Return, 3D / 5D Elbow

Standards:

ASME B16.9, EN 10253-4:2025, JIS B2312/2313 etc.

316 and 316L are molybdenum-bearing austenitic stainless steels with improved resistance to pitting and crevice corrosion compared with 304, especially in chloride-containing environments. 316L is the lower-carbon version and is commonly selected for welded piping systems. Stainless steel fittings made from these grades are widely used in chemical, pharmaceutical, marine, food-processing, water-treatment and other corrosive services.
