Type 316 stainless steel has good weldability and does not require preheating, but requires a similar filler material composition but a high alloy content. Therefore, greater power and lower processing speeds are required, which may result in shortened tool life and difficulty in obtaining a smooth surface. MachiningĪISI 316 stainless steel has higher strength and higher work hardening rate than carbon steel and low alloy steel, so it is more difficult to process. Cold WorkingĪISI 316 grade stainless steel is suitable for cold working such as cold heading, cold drawn and cold riveting, but it is more difficult than carbon steel. When the weldment of 316 grade stainless steel is not suitable for complete annealing, the residual stress can be moderately lowered below 600 ☌, which makes it have good creep resistance. Type 316 SS cannot be hardened by heat treatment, but can be hardened by cold working. Forging TemperatureĪISI 316 stainless steel typical forging temperature is 925-1260 ☌ (1700-2300 ℉). The temperature for homogenization heat treatment is about 1250 ☌. Type 316 stainless steel surface should be carefully cleaned before annealing and must be protected with vacuum, hydrogen or inert gas in order to prevent the formation of an oxide layer during the annealing process. Solution Treatment (Annealing Temperature)Īnnealing at a temperature range of 1010-1065 ☌, then cooling rapidly. AISI SAE ASTM 316 Heat TreatmentĪISI 316 stainless steel heat treatment are summarized in the following content, such as annealing, hardening, etc. 316L stainless steel has better carbide precipitation resistance than AISI 316 and can be used in the above temperature range. In the range of 427 ☌ – 857 ☌, it is better not to continuously use SS 316, but when 316 stainless steel is continuously used outside this temperature range, it has good heat resistance. SS316 Heat Resistanceģ16 SS has good oxidation resistance in intermittent use below 871 ☌ and continuous use up to 927 ☌ in air. Type 316 steel is not magnetic, but may be weakly magnetic after cold working.

Grade 316 Stainless Steel PropertiesĪISI ASTM 316 stainless steel properties such as chemical composition, physical properties, mechanical properties, magnetic properties are summarized in the tables below. SS 316 Data Sheet & SpecificationĪSTM SAE AISI 316 stainless steel data sheet and specification are listed in the table below, including chemical composition and properties. SS 316 is better than SS 304 in terms of corrosion resistance, heat resistance and certain properties, but the price is higher than AISI 304, for more details, please check stainless steel grade 304 vs 316, and 316 vs 316L. Due to the addition of Molybdenum (Mo), SS 316 has a great improvement in corrosion resistance and certain properties compared to SS304.ģ16L stainless steel (UNS S31603) is the low carbon version of AISI 316. AISI 316 stainless steel (UNS S31600) is the second most commonly used austenitic stainless steel.
