Sep 10, 2020· The yield strength is the number of pounds per square inch (kiloPascals) it takes to produce damage or deformation to the yield point. Measured using Poisson's ratio (the ratio of lateral to axial strain), which states that when a metal is strained in one direction, there are corresponding strains in all other directions.

Dec 13, 2016· 304/304L STAINLESS STEEL 1 Type 304 Stainless Steel is a variation of the base 18-8 grade, with a higher chromium and lower carbon content. The lower carbon content minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. In some instances Type 304 can be used in the "as-welded" condition.
