Feature

This kind of alloy is characterized by high elasticity, corrosion resistance and weak magnetism or non-magnetism.

Application

They are usually used for making instruments, wireless elastic sense organs, bellows, diaphragms, corrugated pipes, springs, sensors, shock dampers and etc.

Note: We have succeeded in researching and producing 3J02(36НХТЮ5М), through adding 5% Mo element to increase strength. We are still doing researching to produce 36НХТЮ8M.
