Stainless Steel 316 Butt Weld Fittings can be worth the expense if you need to have superior corrosion resistance. SS 316 Elbow makes them ideal for chemical resistant and salt water applications, as well as having the condensed, light and commanding features. Heavy welded sections in Stainless Steel 316 Tee may require post-weld annealing. Unfortunately, concentrations of chloride in seawater can vary, and splash zones can cause concentrations to increase dramatically by evaporation in Stainless Steel 316 Reducer, thus the corrosive severity of marine environments can vary. A color develops as a result of a chemical reaction and, generally, the intensity of the color in Stainless Steel 316 Cross can be used to estimate the amount of alloying component present. Stainless Steel 316 Stub End has excellent weldability by all standard fusion methods, both with and without filler metals. Stainless Steel 316 Bend is suitable for welding because it has carbon content to avoid carbide precipitation in welding applications.

 

LIST OF STAINLESS STEEL 316 PIPE FITTING

The best corrosion resistance in SS 316 End Cap is obtained when the final annealing temperature is above 1070 Degree C. Stainless Steel 316 Dish Cap also offers higher creep and tensile strength at elevated temperatures and strength properties. These 316 Stainless Steel Pipe Fittings is subject to work hardening during deformation and is subject to chip breaking. SS 316 Butt Weld Fittings has a good application for lifting thin panels with a low reinforcement grade.
