EN26

APPLICATIONS:

The steel is suited to applications where high surface pressures exist and friction is to be resisted as in the case of severely loaded gears, axles and pinions.

It is used extensively in most industry sectors for applications requiring higher tensile strength and yield strength than 4140, 4340 or En25 can provide.
