826M40 Alloy Steel

826M40 is a 2.5% nickel – chromium – molybdenum high hardenability, high tensile steel, generally supplied hardened and tempered in the tensile range 1000 – 1150 Mpa (Condition V) Rc 31 – 38. Characterized by high strength and toughness in very large sections – similar to EN25 but with higher carbon content, particularly suitable where high surface pressure exists. Pre hardened and tempered EN26 can be further surface hardened by flame or induction hardening, and by nitriding
