4130 Steel Sheet

High tensile strength with mild hardenability.

4130 steel sheet offers high tensile with mild hardenability and is easy to fabricate.

4130 heat-treatble steel sheets off high tensile strength which we guillotine to size, in-house.

Smiths Advanced Metals stocks 4130 steel sheets in a broad range of thicknesses and conditions (normalized and annealed).

4130 offers high tensile with mild hardenability and is easy to fabricate. The alloy provides greater strength and hardness when compared to standard carbon steel, and the strength to weight ratio of the material is also good. 4130 responds well to nitriding, which results in a product with superior wear and abrasion resistance. This grade also promotes high oxidation resistance, andweldability is also good though pre and post-weld heat treatments will be necessary to avoid cold cracking. Though hardenable, 4130 sheet is relatively easy to machine after heat-treatment and offers a tensile strength of 860 N/mm².

Commercial Applications

4130 finds use in various engineering applications, including aerospace, military and motorsport. We stock 4130 sheets in closer incremental sizes and offer an in-house guillotining service where your steel sheets are cut to tight tolerances.
