SUS440B stainless steel has higher hardness than SUS440A steel and higher toughness than SUS440C steel.SUS440B is used for cutting tools, gauges and bearings.
It has high hardness and good wear resistance, and its disadvantage when grinding is that it is more viscous,
It heats up quickly, but is easier to grind than any carbon steel, and much easier to cut stock with a hand saw.
AISI 440B stainless steel properties:
1. higher strength
2. Higher hardness
3. Ultra-high toughness
4. Excellent wear resistance
5. Good tempering resistance
6. Excellent corrosion resistance
7. Good high temperature dimensional stability
