Austenitic SS 316 SS316 steel is an austenitic chromium-nickel stainless steel that contains between 2 and 3% molybdenum. 316 Stainless steel has better corrosion properties due to its molybdenum content which improves its resistance to pitting in chloride ion solutions and makes it strong for higher temperatures.
Type 316L Stainless Steel Properties. 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
Physical Properties of type 316 and 316L steels: Density: 0.799g/cubic centimeter. Electrical resistivity: 74 microhm-centimeters (20 degrees Celsius) Specific Heat: 0.50 kiloJoules/kilogram-Kelvin (0–100 degrees Celsius) Thermal conductivity: 16.2 Watts/meter-Kelvin (100 degrees Celsius) Modulus of Elasticity (MPa): 193 x 10 3 in tension.
AS 1554.6 pre-qualifies welding of 316 with Grade 316 and 316L with Grade 316L rods or electrodes (or their high silicon equivalents). Heavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance. This is not required for 316L. Grade 316Ti may also be used as an alternative to 316 for heavy …
