0.4% medium carbon steel. A general purpose steel for applications requiring added strength and superior tensile properties to mild steel specifications.0.5% carbon steel giving higher tensile than EN8. Can be induction or flame hardened.1% chromium molybdenum high tensile steel. Suitable for highly stressed applications where greater strength is required.Nickel chromium molybdenum high tensile steel. Has good wear and shock resistance and is suitable for tensile ranges up to 1550 Nmm2.414% nickel steel. Achieves a good through hardness with air or oil hardening. It is capable of taking a good polish and is widely used as a plastic mould steel.High carbon alloy steel which achieves a high degree of hardness with compressive strength and abrasion resistance.Nickel chromium case hardening steel. Give a very hard surface with a strong core and retaining a high degree of toughness.
