![]() Grade 316L stainless steel plate is the low carbon version of 316 stainless steel plate and is extensively used in heavy gauge welded components. Grade 316 stainless steel plate also has outstanding welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. 316 stainless steel plate has excellent forming and welding characteristics. It has particularly higher resistance to pitting and crevice corrosion in chloride environments. The molybdenum gives 316 stainless steel plate better overall corrosion resistant properties than grade 304 stainless steel plate. Grade 316 stainless steel plate is the standard molybdenum-bearing grade of stainless steel plate. Equivalent GradeĪISI 316L SS equivalent to European EN standards (German DIN, British BSI, French NF…), Japanese JIS standards, Chinese GB standards, ISO and more.316 and 316L Stainless Steel Plate Overview 316N was developed after adding a small amount of nitrogen (N), SS 317L was developed from the addition of nickel (Ni) and molybdenum (Mo). For example, after adding a small amount of titanium (Ti), SS 316Ti was developed. On the basis of 316, many steel types were developed. Stress Relieving: Stress relief is usually not required unless you know or suspect that the environment will cause stress corrosion. AISI 316L (UNS S31603) Physical PropertiesĪnnealing: The recommended annealing temperatures for 316L wrought steel is 1400 ☌ (1900 ☏). The datasheet below gives SS 316L density, melting point and magnetic permeability. The tables below give AISI 316 vs 316L stainless steel mechanical properties such as yield strength, tensile strength, elongation and hardness in different product forms and conditions.Īnnealed, Cold finished, Dia.≤12.7 mm (0.5 in.)Īnnealed, Cold finished, Dia>12.7 mm (0.5 in.)ġ MPa = 1 N/mm2 ASTM SAE AISI 316L Physical Properties SS316 and SS316L Chemical Composition (%)ĪSTM AISI 316L stainless steel properties are listed in the tables below, including mechanical properties and physical properties. Difference Between SS316 and SS316L Chemical Compositionĭifference between 316 and 316L stainless steel composition is summarized in the tables below. Material 316L meaning: “3” refers to 300 series austenitic chromium-nickel alloys, L is stand for “Low carbon”. SS316 also has good resistance to chloride attack and is therefore commonly used in the marine environment. SS316L can be used in applications where annealing cannot be performed after welding and maximum corrosion resistance is required.ĪISI 316 (UNS S31600) and 316L (UNS S31603) are US steel grades, SUS 316 and SUS 316L are Japanese stainless steel grades.īecause of the additional molybdenum in this steel, the overall performance of the steel is better than that of AISI 310 and AISI 304 stainless steel. In addition, AISI 316 might lead to stress-corrosion cracking or dimensional instability in service after welding, so postweld heat treatment is required for stress relief to reduce intergranular corrosion or stress-assisted intergranular corrosion, while SS316L generally does not have these problems. Since SS 316L has a much lower carbon content than SS316, the welding of 316L stainless steel is better than SS 316. SS316 has a 0.08% max carbon content while SS316L (UNS S31603) only has a maximum 0.03% carbon content. The main difference between 316 and 316L stainless steel is the level of carbon content, weldability, corrosion resistance and mechanical properties. Both AISI 316 vs 316L stainless steel are molybdenum (Mo) containing austenitic stainless steel grades.
