817M40 [EN24]

Description:

817M40 grade steel is a general purpose steel used for a wide range of engineering parts. It is capable of being heat treated to produce a wide range of tensile strengths combined with good ductility and resistance to shock. It has good hardenability, enabling it to be used for medium tensile strengths in fairly large sections, and possesses with good resistance to wear. At low temperatures good impact values can also be obtained. 817M40 is a 1.5% Ni-Cr-Mo high hardenability, high tensile strength steel. It is generally supplied in the Hardened and Tempered condition in the tensile range of 850 – 1000Mpa (T Condition) but can be heat treated to 850 – 1550Mpa dependent on section size (T – Z Condition). It could also be supplied in the annealed condition suitable for pre-heat treatment machining. This grade is very popular and widely used for many high strength applications where a good combination of strength and impact properties are essential in fairly large components.

Typical Applications:

This alloy is used in most industry sectors for a wide variety of applications including high strength machine parts, collets, spindles, gears, Engine Con Rods, HT bolts, shafts, couplings etc.

Form of supply:
