AISI 1050 carbon steel is a high-carbon, cold rolled steel containing approximately 0.50% carbon that can be hardened by heat treatment to a maximum hardness of approximately Rockwell C 58. Molybdenum, chromium, nickel, copper, and aluminium are present in small quantities. AISI 1050 carbon steel is used for the manufacture of blades, brackets, brake discs, clips, clutches, springs, washers and gears and for a wide range of applications that can make use of its good combination of mechanical properties.

1. High strength, good elastic properties, low cold deformation plasticity, medium machinability, poor weldability, no temper brittleness, low hardenability, and easy to crack when water quenching. It is mostly used after normalizing, tempering after quenching, or high-frequency induction hardening.
2. Used as mechanical parts with high wear resistance requirements, low dynamic load and impact, such as forged gears, tie rods, rolls, shaft friction discs, machine tool spindles, engine crankshafts, agricultural machinery plowshares, heavy-duty mandrels, etc., and Minor shock absorbing springs, spring washers, etc.
3. This standard applies to high-quality carbon structural steel bars with a diameter or thickness not greater than 250mm. After negotiation between the supplier and the buyer, high-quality carbon structural steel bars with a diameter or thickness greater than 250mm can also be provided.
Due to its mix of useful properties, this material is utilized for a very large variety of applications. AISI 1050 spring steel is most commonly known to be used for blades and related products for its strength. When it comes to AISI 1050 springs, these are usually found low stressed applications or static load applications.
