Product Description
Alloy Steel 1.5752/14NiCr14 EN36 3310 Hot Rolled Steel Bars
1: BS EN36 Steel Introduction
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. Once hardened and carburised, it can achieve a core strength of up to 1230 N/mm2.
It is used specifically in heavy duty and highly stressed applications due to its hardenability, toughness and high core strength. And EN36 also offers excellent fatigue resistance.

5: BS EN36 Steel Mechanical Properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment will cause different mechanical properties, such as normalized, tempered, QT. If you want to know the properties, please kindly contact the salesman.
