Frequently asked questions about 1.4571
What does titanium stabilisation do in 1.4571?
Titanium binds the carbon and prevents intergranular corrosion – even at higher temperatures and after welding without heat treatment.
When to use 1.4571 instead of 1.4404?
At higher service temperatures or when post-weld heat treatment is not possible.
