EN40B (722M24)

EN40B NITRIDING STEEL HELD ON STOCK AND DELIVERED THROUGHOUT THE INDIA


EN40B (722M24)

722M24 - EN40B is a 3% Chromium Molybdenum Nitriding Steel.

EN40B is chromium-molybdenum nitriding steel characterized by its suitability for nitriding which promotes high wear resistance. The material is supplied in the hardened and tempered 'T' condition, EN40B offers good toughness and good ductility. The nitriding process produces a scale free surface with minimal distortion. EN40B in T condition has a tensile of 850-1000 N/mm. It is characterized by its suitability for nitriding, which can give a hard wear resistant case in the range of 61-65Rc. The relatively low temperature of the nitriding process produces EN40B components with a scale free surface, with minimum distortion during the heat treatment process. EN40B may be used in its supply condition (usually T) for applications and components which require a high tensile steel strength and high creep strength at temperatures up to 600C. EN40B nitriding steel stockholders and suppliers, delivering to the whole of the India.

Key Features :

EN40B Engineering Steel offers high wear resistance. The alloy also offers good shock resistance and good toughness and ductility. EN40B is supplied in the hardened and tempered 'T' condition. It is classed as nitriding steel.

 

Applications :

EN40B is suited for applications that require excellent resistance to wear and abrasion combined with high fatigue strength. Typical applications include shafts, extruders, gear wheels, drills, guides, pins, spindles and bolts. Widely used in the automotive, textile and general engineering industries.

 

Typical applications of EN40B / 722M24 grade steel :
