ASTM 1030 Steel

What is ASTM 1030?

A high-carbon steel containing approximately 0.30% carbon that can be hardened by heat treatment to a maximum hardness of approximately Rockwell C 50.

Applications of A1030

Soft annealed high carbon steel is meant for uses requiring moderate forming, while soft spheroidized annealed product is meant for uses requiring maximum cold forming.

The soft spheroidized annealed product is processed to give the lowest hardness for maximum formability.

This grade of steel is used for machinery parts, brackets, brakes, clips, clutches, springs, washers and for a wide range of uses that can make use of its good combination of mechanical properties.

We will be glad to help you select the exact grade for your needs.

Specifications of ASTM 1030

  • Strength, Yield Strength ksi (MPa), Tensile Strength ksi (MPa): Strong, 65 (380-550)
    For higher strength and lower weight, consider High-strength, Low-alloyx
  • Formability: % Elongation: Very Good, 23-25%
    For even better formability consider Drawing Steel
  • Joining – Very Good
    may normally be welded without special precautions using any of the standard arc or resistance welding methods.
  • Corrosion Resistance – Good
    Galvanizing will slow corrosion. For longer life in harsh chemical conditions, consider Galvanized or Coated Steel
  • Chemistry  A ‘plain’ steel without expensive alloying elements.
  • Cost – Relatively low.  
    Good when thinner, stronger, or more formable steels will not add value.
