While it still shares many of the properties of other 316 grades, the addition of titanium protects 316Ti from precipitation at high temperatures, even with prolonged exposure. This grade contains a small amount (usually only 0.5%) of titanium. Stainless steel 316Ti is known as a stable grade of the 316 type and is also one of two 316 stainless steels recommended for higher temperature applications. Grade 316H refers S31609, carbon content 0.04% to 0.10%, it provides higher temperature resistance than 316L. In addition, 316 does not require post-service annealing to maximize its corrosion resistance, but annealing may be used in some cases. Many of the same working practices that are valid for Type 316 can also be used for 316L, including weldability and cold work hardening. In terms of heat resistance, 316L exhibits better creep resistance, fracture stress resistance and overall strength than other stainless steel grades. The metal also exhibits resistance at extremely low temperatures, even down to cryogenic levels.
Again, its low carbon content protects it from carbon precipitation. This stainless steel is widely used for welding the components, its special carbon content combined with welding ensures maximum resistance to general corrosion, especially applicable for heavy duty components.ģ16L is considered more resistant to oxidation than Type 316, especially in warm marine environments. Therefore, 316L is suitable for applications where carbon precipitation needs to be avoided. 316L maximum carbon content 0.03% which 316 maximum 0.08%, higher carbon will increase intergranular corrosion. Grade 316L refers S31603 UNS desination 1.4404, it has better corrosion resistance than TP316 because of the lower Carbon content. ASTM A312 TP316/316L/316H/316Ti/316LN Chemical Compositionģ16 Stainles Steel Pipe Mechnical StrengthĪSTM A312 TP316 316L 316H 316LN Mechnical Strength 316L/TP316L Stainless Steel Pipe 316 has excellent toughness and mechanical properties at sub-zero temperatures, suitable for cold rolling, continuous mill plate and plate millplate form, thickness range up to 60 inch. Compare to 304 stainless steel, 316 contains a higher percentage of molybdenum (Mo 2%-3%) and nickel (Ni 10% to 14%), Molybdenum has better overall corrosion resistance, especially for pitting and crevice corrosion in chloride environments. Type 316/ 316L/316H are austenitic stainless steel intended for use in applications that require high strength, toughness and workability, as well as enhanced corrosion resistance. Stainless steel flanges: ASTM A182 F316/F316L/F316H Stainless steel pipe fittings: ASTM A420 WP316/WP316L/WP316H/ 316 stainless steel pipes, fittings, flanges, plates reference standard: It covers TP316, TP316L, TP316H, TP316Ti, TP316N, TP316LN, major difference between these grade is the chemical composition on carbon, Ti, Nitrogen.
