AISI 1566 High Carbon Manganese 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.
Manganese helps improve hardenability over comparable plain carbon grades.
Heat treatment can produce high strength and hardness.
The grade is suitable for selected resilient and spring components.
Higher hardness can improve performance in wear-oriented service.
AISI 1566 High Carbon Manganese Steel is selected for applications where strength, hardness, wear resistance or controlled hardenability are important.
Used for selected spring and resilient components.
Selected for heat-treated automotive parts and machine components.
Used for selected wear-resistant components.
Suitable for shafts, pins and other load-bearing parts where hardenability is useful.
Specify the required heat-treatment condition and section size when using AISI 1566.
Manganese-assisted hardenability can help develop useful properties through a suitable cross-section.
Critical parts should be supplied to the governing specification with certified mechanical test results.
No one-to-one Werkstoff number was verified for AISI 1566 High Carbon Manganese 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.
