ASTM A830 Steel Grades
The ASTM A830 specification is the Standard Specification for Plates, Carbon Steel, Structural Quality, Furnished to Chemical Composition Requirements and supplied in the as-rolled (green) condition. Typically, the as-rolled plates undergo subsequent processing to produce the desired material properties. Low carbon grades (e.g. 1008) are used in applications where formability is important. Medium carbon grades (e.g. 1020) are used in applications where a combination of machinability and formability are needed. High carbon grades (e.g. 1030 & 1045) are used when hardenability is important for subsequent heat treating.
