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.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.

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.

Typical uses are: Axles, Connecting Rods, Die Holders, Hydraulic Shafts, Spindles, Motor Shafts, Pins, Rams, Rolls, Sockets, Tool Holders, Torsion Bars etc..
 

Heat Treatment

Annealing

Heat to 790 oC - 840 oC, hold until temperature is uniform throughout the section and cool in furnace.

Flame or Induction Hardening

EN26 hardened and tempered bar can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness in excess of Rc 50.

Parts should be heated as quickly as possible to the austenitic temperature range (820 oC - 850 oC) and required case depth followed by an immediate oil or water quench, depending upon hardness required, workpiece size/shape and quenching arrangements.Following quenching to hand warm, most components should be tempered between 150 oC - 200 oC to remove quenching stresses in the case. This will have little effect on case hardness.

Hardening

Heat to 820 oC - 850 oC, hold until temperature is uniform throughout the section, soak for 10 - 15 minutes per 25 mm section, and quench in oil, water, or polymer as required.*Temper immediately while still hand warm.

Nitriding

EN26 hardened and tempered bar can also be successfully nitrided, giving a surface hardness of up to Rc 60. Nitriding is carried out at 490 oC - 530 oC, followed by slow cooling (no quench) reducing the problem of distortion. Parts can therefore be machined to near final size, leaving a grinding allowance only. The tensile strength of the core is usually not affected since the nitriding temperature range is generally below the original tempering temperature employed.N.B. Nickel is inert to the action of nitrogen and in general resists its diffusion into steel, and this can result in a lower case hardness or longer nitriding cycle times for steels containing nickel such as EN26.
