It’s durable, strong, and easy to work with. 304 on 304 will gall at low stress (maybe a couple of ksi according to Armco). During sheet metal part bending, the inside bending surface is compressed, whereas the outer surface is stretched. q / A = [(17 W/(m K)) / (2 10 -3 m)] (80 o C)The K-factor is the most popular way of calculating the bend allowance and bend deduction, but there are multiple ways that this calculation can be done. After 304 stainless steel, 316 stainless steel is the second most widely used steel, primarily in the food industry and in surgical equipment. If ɛ r is roughness of pipe (mm) and D is the diameter of pipe (mm), then relative roughness can be expressed. 4301 (AISI 304) when heated in open air: These colors, also called heat tint, depend on four factors: Steel chromium content.
