SS540 Steel Angle
JIS G3101:2004 SS540 angle steel contains 0.30% carbon and 1.60% manganese, which greatly improves its strength. Compared to SS400 and SS490, SS540 has higher strength - 400 MPa yield strength and 540 MPa tensile strength. The high strength makes it popular in applications where strength is required but weight is an issue.
SS540 angle steel has many sizes, the following table includes equilateral and unequal sides. Custom specifications available on special order. In addition, there are three surface treatments to choose from: blackening, hot-dip galvanizing, and spray painting.
