1095
Data verified1095 is the highest-carbon steel of the standard SAE bar series: very hard and wear resistant after quenching, but brittle and shallow-hardening because of its low manganese. It is a traditional blade and spring steel for thin sections.

Applications & Processing
Applications: Knives and cutlery, springs (thin), saw blades, shear blades, feeler gauges.
Processing: Water/brine quench risk of cracking — oil preferred where section allows; low toughness in the hardened state; not weldable in practice.
FAQ
- 1095 vs 1084 for blades?
- Both reach similar hardness. 1084 has more manganese, so it hardens a little deeper and more evenly; 1095 is more widely stocked as spring strip.
