EN26 HIGH TENSILE STEEL
EN26 (826M40) Round Bars
EN26 High Tensile Steel Round Bar / Rods
EN26 (826M40) is a 2.5% Nickel Chromium Molybdenum High Hardenability, High Tensile Steel. Characterised by high strength and toughness in very large sections - similar to EN25 but with higher carbon content, particularly suitable where high surface pressure exists. It is suitable for applications which require higher tensile and yield strength than EN24 or EN25 specifications.
Pre hardened 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.
826M40 steel is still often referred to as EN26 steel - its equivalent grade under the previous BS 970: 1955 standard.
