Specifications: Various specifications and sizes can be customized according to customer requirements.

Physical and chemical properties

3J40 is a shaft tip alloy used to make shaft tips and small shafts of instruments.

It has high elastic limit, proportional limit, lasting limit, low elastic after-effect, elastic hysteresis, stress relaxation, and has a certain elastic modulus and shear modulus.

Some alloys also have a low temperature coefficient of elastic modulus (shear modulus) and a high mechanical quality factor.

The main purpose:

Instrument, the shaft tip of the instrument.

Main features:

Non-magnetic, shock-resistant, wear-resistant.
