|
EN26 is a 2.5% nickel chromium molybdenum high tensile steel, usually supplied hardened and tempered to either 'V' or 'W' condition. EN26 is suitable for applications which require higher tensile and yield strength than EN24 or EN25 specifications. EN26 round bar is available from stock. When required EN26 can be induction or flame hardened. EN26 can also be nitrided.

Heat to 1150 to 1200°C and hold at temperature until throughly soaked and suitable to forge. Do not forge below 850°C.
To harden EN26 first heat the component to 820 to 850°C and hold at temperature until throughly soaked. Quench the EN26 component in oil, water or polymer as required. EN26 can be flame or induction hardened to achieve a high surface hardness.
To temper EN26 heat the component to the required tempering temperature (450 to 660°C), thoroughly soak for 1 hour per 25mm thickness of section, cool in air.
EN26 can be nitrided to give a surface hardness of up to 60HRc. Heat to 500 to 530°C and hold for sufficient time to develop the case depth required, no quenching is required.
To stress relieve EN26 heat the component to 640 to 660°C and hold until temperature is uniform through the section. Soak the EN26 component for 1 hour per 25mm thickness of section and cool in air.

Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
