Grade | C | Cr | Fe | Mn | Mo | Ni | N | P | Si | S |
316 | 0-0.08 | 16.0-18.0 | 62.0-72.0 | 0-2.0 | 2.0-3.0 | 10.0-14.0 | 0-0.1 | 0-0.045 | 0-0.75 | 0-0.03 |
410 | 0.08-0.15 | 11.5-13.5 | 83.5-88.4 | 0-1.0 | 0 | 0-0.75 | 0 | 0-0.040 | 0-1.0 | 0-0.03 |
Cr content is an important factor to judge the corrosion resistance of alloy steel. The Cr content in 316 is 16-18%, while the Cr content in 410 is about 11.5-13.5. Therefore, the corrosion resistance of 316 stainless steel is greater than 410 stainless steel. However, the 410 stainless steel contains at least 11.5% Cr, sufficient to provide corrosion resistance. After quenching and tempering, relatively considerable corrosion resistance can be obtained
Hardness | Break elongation | Fatigue strength | Tensile strength | Yield Strength | |
316 | 160-360 | 8.0-55.0 | 210-430 | 520-1180 | 230-850 |
410 | 190-240 | 16.0-22.0 | 190-350 | 520-770 | 290-580 |
It can be seen in the table that the tensile strength of 316 stainless steel is 520-118, and the tensile strength of 410 stainless steel is 520-770. The yield strength of 316 stainless steel is 230-850, while that of 410 stainless steel is 290-580. 316 stainless steel can be used in a wider range of fields, while 410 stainless steel has higher stress, suitable for some specific strength occasions.
Because 316 stainless steel contains a lot of molybdenum, so the price of 316 stainless steel is higher than 410 stainless steel. 316 stainless steel is better suited to work in corrosive environments.
Compared with 410 stainless steel, 316 stainless steel has stronger corrosion resistance and weldability, and is used more widely. But it is also more expensive. 316 stainless steel in rust and corrosion resistance is far better than 410 stainless steel, but in some special occasions, 316 stainless steel can not replace 410 stainless steel
