Mechanical Properties

For 30MnB5 grade, the chemical composition and, where applicable, the material delivery condition are certified. The final mechanical properties depend on the subsequent quenching heat treatment, which allows high levels of hardness, mechanical strength and wear resistance to be achieved.

Tolerances

Tolerances on the dimensions and on the shape UNI EN 10051
Surface condition UNI EN 10163-2

Certifications
