What is EN353?

EN353 is a very high strength steel alloy which is hardened and tempered before supplying and has nickel, chromium, molybdenum making it high tensile steel strength, with good ductility and wear resistance.

What is EN36 steel?

EN36 (655M13) is a nickel-chromium-molybdenum based case hardening engineering steel which is specifically designed for carburising. The addition of nickel increases shock resistance and toughness whilst the chromium increases the material’s hardenability giving it a uniformed hardness.

What is the difference between EN8 and EN9?

EN8 :- 0.4% medium carbon steel. A general purpose steel for applications requiring added strength and superior tensile properties to mild steel specifications. EN9 :- 0.5% carbon steel giving higher tensile than EN8.

What is the difference between hardenability and hardness?

To recap: hardness is how hard the actual steel is based on the resistance of penetration. Hardenability is the potential the steel has to be hardened by thermal treatment. Each of these has tests associated to come up with a measurement that is quantifiable.
