Valve seats,Rolling element bearings,Ball beatings,Gage blocks,Moulds,Dies
Cutlery,Valve components,Measuring instruments
Carbon: 0.95-1.25% This increases hardenability and wear resistance, but decreases toughness in higher amounts.
Manganese: max. 1.00% This is added to reduce brittleness and improve forgeability, hardenability, and reducing deformation.
Silicon: max. 1.00% This is a deoxidizer and improves hot-forming properties.
Chromium: 16.00-18.00% Added only to high alloy tool steels, this improves hardenability, high wear
resistance, toughness, and corrosion resistance.
Molybdenum: max. 0.75% Improves deep hardening and toughness.
