Grade 316 is part of the ASTM A182 standard, which applies to valves, flanges, fittings, and other components exposed to pressure and temperature conditions. This standard covers stainless steel materials, with Grade 316 classified as forged stainless steel.
The buyer is responsible for specifying the grade of items such as valves, fittings, flanges, etc., that need to be procured. This selection depends on the design requirements, operating conditions, mechanical properties, high-temperature specifications, or corrosion resistance characteristics.
All cast grades, including 304, 304L, 316, and 316L, must undergo appropriate heat treatment to meet the required design and chemical specifications.
Grade 316, categorized as forged stainless steel, has its chemical properties detailed in the table below.
| Carbon % | Manganese % | silicon % | sulfur % | phosphorus % | Chromium % | Nickel % | Molybdenum columbium (niobium) % |
| 0.08 | 1.50 | 1.50 | 0.040 | 0.040 | 18.0-21.0 | 9.0-12.0 | 2.0-3.0 |
