Seamless Stainless Steel Tubes Introduction
Incoloy Alloy 800H/800HT are a controlled composition alloy, used in applications that need high temperature creeping resistance. They offer good resistance in the variety of acidic and sulfur containing media. The blend of mechanical and thermal processing enables Nickel 800H/HT to tolerate higher stresses than those of traditional alloys.
Seamless Stainless Steel Tubes Key Features:
- Incoloy 800H/HT offers enhanced high temperature creeping resistance
- Higher strength than Incoloy 800 grade
- Stress cracking resistance up to 1100oF
- Great resistance to carburizing, oxidizing and nitriding media.
