Alloy Steel

Assorted alloy steel threaded fittings including tees and nipples with a silver metallic finish.

Alloy Steel Fittings are made from carbon steel enhanced with elements like chromium and molybdenum to deliver exceptional strength at high temperatures, improved hardenability, and strong resistance to oxidation. Designed for demanding industrial environments, these fittings perform reliably under extreme thermal stress and high‑pressure conditions.

Fluids: Steam, Chemicals, Gas, Oil

Industrial Applications: Oil & Gas, Power Plants, Petrochemical

Highlights: Exceptional High-Temperature & High-Pressure Performance

Considerations: Requires Specialized Welding Procedures and Post-Weld Heat Treatment
