Your specialist for sawn steel from forged billets directly from stock in Texas.
We provide metal cutting services.


AISI 347 is a stainless, austenitic chromium-nickel stainless steel alloyed with niobium. Due to the carbide former niobium, the material is resistant to intergranular corrosion in the welded condition, irrespective of thickness and cross-section.

In nuclear power plant construction, the stainless material steel 347 ss has established itself through its high corrosion resistance. In the private sector, it is used for household appliances. The material is also often used in the film and photographic industries.

In the chemical and food industries, the material grade AISI 347 ss is often used for tanks and apparatus.

We supply the material as sawn steel blanks directly from stock.

The material 347 ss is suitable for welding with all common welding methods. No special measures or post-weld heat treatments are required.

Corrosion resistance

Good resistance to a wide range of environments in the chemical, textile, oil refining, dairy and food industries.

Hot forming

Hot forming should be carried out between 1120°C – 1020°C. This is followed by cooling in air or water.


Cold forming is possible
Machining processing only possible to a limited extent
Polishability unsuitable
