HN70U is a heat-resistant steel alloyed with chromium, nickel, and aluminum, containing up to 1% iron. The designation HN70U stands for:
- H: 26-29% chromium
- N70: 65-71% nickel
- U: 2.8-3.5% aluminum
This grade offers excellent heat resistance and strength at high temperatures. It is suitable for welding only under certain conditions—preheating to 100-120°C is necessary, and additional heat treatment is needed after welding. The alloy is not suitable for use in sulphurous environments.
You can purchase HN70U from the Evek GmbH online store at competitive prices. Orders can be placed 24/7.
