Product Introduction

1.4958 Nickel Alloy 800H Tube contains Nickel (30-35%), Chromium (19-23%), and Iron (balance). The alloy also contains controlled levels of Carbon, Aluminum, and Titanium to improve its creep and rupture properties. Known for its excellent resistance to high temperatures and pressures, Incoloy 800H Tube can withstand temperatures up to 1200°F (650°C) and above. It also resists oxidation and carburization in high temperature environments. We are a n08810 supplier with 15+ export experience, contact us for more information and free quotes!
