316 / 316L Stainless Steel Tees

Grade: 316/316L

Types:

Equal Tee, Straight Tee, Reducing Tee, Seamless Tee, Welded Tee, Butt-Welding Tee.

Standards:

ASTM B16.9, EN10253-4, JIS B2312/2313

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.
