AISI 316L stainless steel is a modified ultra-low carbon Cr-Ni-Mo series austenitic stainless steel based on AISI 316. It is recommended for parts that cannot be annealed after welding in certain corrosive environments. The addition of molybdenum can provide pitting resistance in phosphoric acid and acetic acid and dilute chloride solutions and corrosion resistance in sulfurous acid. SS316L is resistant to carbide precipitation in the temperature range of 425-870 °C (800-1600 °F), so normal welding can be performed without reducing corrosion resistance. However, when it is heated and kept in the sensitization temperature range for a long time during use, a large amount of carbides will precipitate, so it is usually recommended to use it below 425 °C (800 °F).
Type 316L stainless steel density is 0.289 lb/in3 (8.0 g/cm3); melting point is 1375-1400 °C (2500-2550 °F); 0.2% yield strength is minimum 25 ksi (170 MPa) in annealed and hot finished condition, minimum 45 ksi (310 MPa) in annealed and cold finished condition; Minimum tensile strength is 70 ksi (485 MPa) in annealed and hot finished condition, ≥ 90 ksi (620 MPa) in annealed and cold finished condition; Maximum Brinell hardness is 217 HB, Maximum Rockwell hardness is 90 HRBW; Thermal conductivity is 12.1 W/m·K at 20 °C (68 °F), 16.3 W/m·K at 100 °C (212 °F).
