Wear resistance of stainless steel
Thread Content
Which brother can provide the order of wear resistance for several commonly used austenitic stainless steels, such as 304, 304L, 316, 316L, 321, etc.?
What parameter is used to measure wear resistance? Is it hardness? If it comes to hardness, the factors that influence it include: cold/hot rolling condition, heat treatment method, product shape, whether it has been processed, the temperature at which it is found, surface condition, etc. (That’s all I can think of for now.) But one thing is certain: under identical conditions, those without the letter L are harder than those with L, due to their higher carbon content.
304 is more wear-resistant than 316; generally, the contents of C, Cr, and Ni in metals are related to their hardness. It seems that it’s not just hardness; there are other parameters such as the coefficient of friction, friction curve, and wear amount.
In terms of hardness values, the wear resistance is essentially the same under identical operating conditions.
