316 and 410 stainless steel are used for diverse applications. While 410 belongs to martensitic stainless steel, 316 is regarded as austenitic stainless steel.
Features of SS316
Stainless steel SS316 is a standard molybdenum stainless steel that includes corrosion-resistant properties. This stainless steel has high resistance to crevice corrosion and pitting in chloride surroundings. This stainless steel has amazing welding and forming characteristics. It has diverse applications in the architectural, industrial, and transportation sectors. 316 stainless steel is known for its excellent welding feature. There is no need for post-weld annealing in the case of welding into thin sections.
Features of SS 410
Stainless steel 410, on the other hand, is a basic form of martensitic stainless steel similar to most non-stainless steel and can also be hardened by heat treatment. SS 410 chemical composition includes minimal 11.5 % chromium and has corrosion resistance features. Once it is hardened, tempered, and polished properly, it can gain a maximum level of corrosion resistance. It is also a general-purpose bearing grade mostly supplied in machinable and hardened conditions. This stainless steel is applied where corrosion resistance, moderate heat, and high strength are required.
Heat Resistance
410 stainless steel have also better scaling resistance at 650 degrees Celsius. But the mechanical properties will start reducing at a temperature between 400-580 °C.
Corrosion Resistance
The main element to test the corrosion resistance property of alloy steel is Cr content. 16-18% of Cr content is present in 316 stainless steel, while 11.5-13.5% of Cr content is present in 410 stainless steel. The minimum content of 11.5% Cr is present in 410 stainless steel, sufficient to offer corrosion resistance. A considerable amount of corrosion resistance property can be obtained after tempering and quenching.
Tensile Strength
The tensile strength of 410 stainless steel varies between 520-770, while 316 stainless steel is 520-770. Regarding yield strength, 410 stainless steel is 290-580, while 316 stainless steel has a yield strength of 230-850. You can use 316 stainless steel in diverse fields, whereas 419 stainless steel can be used in areas with high stress and is perfect for certain strength occasions.
Welding
You can use every conventional welding method for welding Grade 410 steel. However, materials must be preheated at 150-260°C, and then post-weld annealing treatment must be followed to mitigate cracking.
Cost of 316 and 410 Stainless Steel
Regarding pricing, 316 stainless steel is much more expensive than 410 stainless steel since 316 stainless steel has a high molybdenum content. Also, it is suited to a corrosive environment.
Stainless steel application
The Application for 316 stainless steel are as follows-
The application for 410 stainless steel is as follows-
SS 316 has high corrosion resistance and weldability and is so widely used compared to SS 410 chemical composition. However, it is pricier. When it comes to corrosion resistance and rust resistance properties 316 stainless steel is better however, it can’t replace 410 stainless steel on few special occasions.
