AISI 1074-1075 Sheet/Strip

AISI 1074/1075 – ASTM A682 Sheet and Strip Properties

Please note that we do not sell AISI 1074/1075 high carbon steel or any other materials in raw form. AISI 1074/1075 sheet and strip are material options for custom springs, etc., manufactured by Peninsula Spring.

Out of all high carbon spring steels, AISI 1074/1075 is by far the most common and affordable. AISI 1074/1075 exhibits excellent spring properties, making it the number one choice for most of the custom flat springs, custom sheet metal stampings, and custom metal clips we produce for our customers.

To discuss the material requirements of your next custom manufacturing project, contact Peninsula Spring today.

  • Rockwell hardness: C38-50

Heat Treating AISI 1074/1075

AISI 1074/1075 is delivered in annealed (soft) condition and, after fabrication, is quenched and tempered to a spring tempered condition. A second option is called “Black Scaleless”; this material is already processed to a pre-tempered condition. After fabrication, the pre-tempered material usually undergoes a stress relieving process.

Manufacturing Custom Springs & Stampings with AISI 1074/1075

AISI 1074/1075 is cold drawn and heated to either annealed condition or too high and uniform tensile.
