AISI 1561 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.
Elevated manganese can improve hardenability compared with plain high-carbon grades.
The grade can provide useful strength after suitable heat treatment.
Appropriate heat treatment can produce useful hardness and wear resistance.
Higher hardenability can benefit components with more substantial section sizes.
AISI 1561 High Carbon Manganese Steel is selected for applications where strength, hardness, wear resistance or controlled hardenability are important.
Selected for shafts, pins and structural machine parts requiring hardenability.
Used for selected wear-resistant components.
Suitable for selected heat-treated automotive and machinery components.
Used where higher hardenability than plain carbon grades is beneficial.
Consider hardenability and section size in addition to nominal carbon content when specifying AISI 1561.
AISI 1561 can be heat treated to develop strength and hardness in suitable sections.
For critical components, confirm hardenability requirements and certified material properties.
No one-to-one Werkstoff number was verified for AISI 1561 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.
