CORROSION RESISTANCE

Description

Titanium-stabilised austenitic stainless steel.
It is temperable. It has excellent heat oxidation resistance up to 850°C in continuous service.
It can be welded and resistant to intergranular corrosion.
Indurable by cold working.

It is different to AISI 304 due to the addition of titanium as a stabilising element.
The mechanical characteristics at room temperature are similar to those of AISI 304 while they are superior at higher temperatures.
In solubilized state, it is good for a large number of substances involved in the chemical, textile, petroleum, dairy and food industry.
