EN26 (826M40) Steel Material Overview

EN26 (also known as 826M40) is a 2.5% Nickel-Chrome-Moly alloy steel with high hardenability and high tensile strength . It is used in hardened and tempered condition (Condition V), and it can be further surface hardened by flame hardening, induction hardening, or nitriding to get great surface hardness and wear resistance.

This high-performance alloy steel is used for extreme conditions needing high strength, fatigue resistance and toughness, including undercarriages, aero-engine and airframe parts, heavy duty gears, connecting rods, crank and differential shafts, high strength bolts, electrical motor shafts, turbine discs, gas bottles, mandrel bars for tube manufacture and ordnance parts.

Equivalent Grades and Naming Reference

EN26 is commonly referred to as 826M40 in BS system. In international sourcing discussions it is often cross-referenced with AISI 4340 and 34CrNiMo6 for similar high-strength alloy steel applications. However, final substitution should always be checked against chemistry limits, hardenability, heat treatment route, drawing notes and target mechanical properties before procurement.

Heat Treatment Processes for EN26 (826M40) Forgings

We provide full in-house heat treatment services to get the exact mechanical properties needed for your EN26 (826M40) forging parts:

Hot Forging Process

Heat to a maximum of 1150°C - 1200°C, hold consistent temperature  throughout the section, and start forging immediately. Do not forge below 850°C. After forging, cool the workpiece slowly in sand or dry lime to minimize internal stresses.

Annealing

Heat to 790°C - 840°C, hold consistent temperature throughout the section, then cool slowly in the furnace.

Hardening & Tempering

Hardening: Heat to 820°C - 850°C, hold consistent temperature, soak for 10-15 minutes per 25mm of section thickness, then quench in oil, water, or polymer as required. Temper immediately while the workpiece is still warm.

Tempering: Re-heat to 450°C - 660°C as required, hold consistent temperature, soak for 1 hour per 25mm of section thickness, then cool in still air. Note: don't temper within the 250°C - 450°C range to prevent temper brittleness.

Flame & Induction Hardening

Pre-hardened and tempered EN26 (826M40) steel can be further surface hardened via flame or induction hardening to get high surface hardness and wear resistance for heavy load applications.

Nitriding

Hardened and tempered EN26 (826M40) round bar can be successfully nitrided to get a surface hardness of up to Rc 60. Nitriding is done at 490°C - 530°C, followed by slow cooling (no quench) to minimize distortion. Parts can be machined to near final size before nitriding, leaving only a grinding allowance. The core tensile strength is not affected, as the nitriding temperature is below the original tempering temperature. Note: The nickel content in EN26 resists nitrogen diffusion, which may need a longer nitriding cycle to get the required case depth.

Stress Relieving

Heat to 640°C - 660°C, hold consistent temperature , soak for 1 hour per 25mm of section thickness, then cool in still air to relieve residual stress from machining or forging.
