EN26W Alloy Steel
EN26 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. Prehardened and tempered EN26 can be further surface hardened by flame or induction hardening, and by nitriding. EN26 is used extensively in most industry sectors for applications requiring higher tensile and yield strength than 4140, 4340 or EN25 can provide. Typical uses are Axles, Connecting Rods, Die Holders, Hydraulic Shafts, Spindles, Motor Shafts, Pins, Rams, Rolls, Sockets, Tool Holders, Torsion Bars, etc.EN26 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.

Annealing
Heat slowly to 790-840°C. Hold until the temperature is uniform throughout the steel. Cool in a furnace.
Hardening
EN26W is supplied ready heat treated. If further heat treatment is required annealed EN26 should be heated to 820-850°C and hold until the temperature is uniform through the section. Quench the EN26 steel in oil, water or polymer as required.
Flame and Induction Hardening
EN26 can be flame or induction hardened to obtain a good surface hardness.
