Advantages
- Low carbon content aids in weld-ability
- Can be drilled – bored – sheared and machined
- Can be cold formed
- 5 to 7 times corrosion resistance opposed to carbon steel
- Precise heat treatment
- Boron is used in the steel to intensify harden-ability
- Choice of alloying agents provide a tolerance for rapid cooling and yet maintains a high strength and abrasion resistance
- Ductile
- Tough
