EN31/AISI 52100/100Cr6

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.

Steel Properties

Standard hiqh-speed steel qrade. Itswell-balanced alloy composition forms the basis of its high_touqhn-essand good clllting edge retention, rendenng it $uitable for a large variety of appllcatons.
