AISI 1055 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.
The carbon level allows AISI 1055 to develop high strength and hardness after suitable heat treatment.
The grade can provide useful resistance to abrasive and contact wear when properly heat treated.
Quenching and tempering can be used to tailor hardness, toughness and strength for the application.
AISI 1055 combines strength and toughness with workable machining characteristics in suitable conditions.
AISI 1055 High Carbon Steel is selected for applications where strength, hardness, wear resistance or controlled hardenability are important.
Used for selected shafts, axles and pins where increased strength and wear resistance are required.
Suitable for selected gears, levers and machine components in demanding service.
Used in wear-prone agricultural implements and formed mechanical parts.
Selected for wear-resistant and load-bearing components requiring heat-treatment capability.
Consider section size, required hardness, heat-treatment condition and service loads when specifying AISI 1055.
AISI 1055 can be supplied and processed for a range of hardness and strength levels through suitable heat treatment.
For highly critical components, verify the specified condition and certified mechanical properties against the applicable SAE/AISI material specification.
The commonly listed Werkstoff / EN cross-reference for AISI 1055 High Carbon Steel is 1.1213. Treat this as a grade comparison, not a guarantee of interchangeability. Verify chemistry, product form, condition and governing specification against the supplier certificate before substitution.
