AISI 1090 High Carbon Steel combines a relatively high carbon level with heat-treatment capability. The selected grade is used where strength, hardness, wear performance or hardenability are important.
AISI 1090 can develop high hardness after suitable quenching and tempering.
The hardenable structure can provide useful wear resistance.
Selected heat-treated products can serve spring and resilient applications.
The grade can retain a hard cutting edge in appropriate blade applications.
AISI 1090 High Carbon Steel is selected for applications where strength, hardness, wear resistance or controlled hardenability are important.
Used for selected blades and cutting parts needing high hardness.
Selected for high-carbon spring components.
Suitable for selected wear-prone parts and tooling components.
Used in suitable high-carbon wire and strip products.
AISI 1090 should be specified with a target hardness and heat-treatment condition.
The high carbon level makes correct tempering important for balancing brittleness and hardness.
Critical applications should use certified chemistry and mechanical test results for the exact heat-treated product.
No one-to-one Werkstoff number was verified for AISI 1090 High Carbon Steel in the cross-reference sources checked for this update, so this page does not assign a number. Confirm any proposed EN alternative against the applicable product standard and supplier certificate before substitution.
