Easy-to-Form Wear-Resistant 1095 Spring Steel Sheets

Yield Strength: Not Rated
Hardness: Rockwell B90 (Medium)
Fabrication: See table
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Not Rated
Specifications Met: See table

These sheets are annealed to soften their temper, so they can be formed into shape and then heat treated for spring properties. They’re made from 1095 spring steel, which is more wear resistant than 1075 spring steel because of its higher carbon content. These sheets are often made into parts that will be used under continual stress, such as spring clips and washers. They have been manufactured to ASTM standards for quality and performance.

Easy-to-Form 1075 Spring Steel Sheets

Yield Strength: 50,000 psi
Hardness: Rockwell B90 (Medium)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Rockwell C64
Specifications Met: ASTM A684

These sheets have a softened temper, which is also known as annealed, so they can be easily formed into shape and then heat treated for spring properties. 1075 spring steel is easier to bend than 1095, but it has less bounce-back after heat treating. It is often used for springs and shims.

Easy-To-Form Multipurpose 1050 Spring Steel Sheets

Yield Strength: 38,000 psi
Hardness: Rockwell B74
Heat Treatable: Yes
Maximum Hardness After Heat Treatment: Rockwell C58
Specifications Met: ASTM A682, ASTM A684

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.
