Type 316L stainless steel in a molybdenum bearing austenitic. It is more resistant to general corrosion and pitting than conventional nickel chromium stainless steels such as 302-304. It has the following characteristics:
- Higher creep resistance
- Excellent formability.
- Rupture and tensile strength at high temperatures
- Corrosion and pitting resistance
Shapes vary based on the type of industrial application, e.g. 316l stainless steel pipes, 316l stainless steel elbows, 316l stainless steel tubes, 316l stainless steel pipe fittings, 316l stainless steel u tube, 316l stainless steel flanges and 316l stainless steel gasketssizes to be used in Shipbuilding, Nuclear power, Marine engineering, Petroleum, Chemical, Mining,Sewage treatment, Natural gas and Pressure vessels and other industries..
For example, stainless steel cylinders and tanks are manufactured in 316L stainless steel, have proved to offer exceptional resistance in acidic and hard water areas.
