Frequently asked questions about 1.4435
What distinguishes 1.4435 from 1.4404?
1.4435 has higher nickel and molybdenum contents and is therefore even more chloride-resistant – often for pharma and ultra-pure media plants.
Is 1.4435 easy to weld?
Yes, as a low-carbon austenite 1.4435 is very weldable.
