About Steel

Compare over 50 grades of steel and cast iron to find the right material for you—all with material certificates for traceability.

Multipurpose Formable 1050 Spring Steel Sheets

Containing more carbon than low-carbon steel—but less than 1095 spring steel—1050 spring steel is easily formed into parts such as washers, brackets, and springs before being hardened for use. It resists stress, so it won’t snap when formed or twisted. Because it has a lower carbon content than 1095 spring steel, it’s not as wear resistant.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
