Tool Steel
EN31 Alloy Steel is a high carbon, chromium containing low alloy steel that is through hardening and noted in particular for use as bearings. AISI 52100 has an excellent high carbon alloy steel which provides a high level of hardness with compressive strength and abrasion resistance. This grade of alloy steel is quite regularly utilized for wear resisting machine constituents and for press instruments.
