Briefing

EN 31 is high carbon alloy steel which offers a high measure of hardness with compressive strength and abrasion resistance.

Detailed

Introduction:

EN 31 is a excellent high carbon alloy steel which offers a high measure of hardness with compressive strength and abrasion resistance.
This Grade is quite often used for wear resisting machine constituents and for press instruments which don't advantage a extra complex satisfactory.

Application:

Acceptable for many automobile applications such as heavy duty gear, shaft, pinion, camshafts, gudgeon pins. / Machining components.
