Essential details

Stainless Steel 321H Round Bar is a type of austenitic stainless steel that has a high-temperature strength and resistance to intergranular corrosion. It contains higher amounts of carbon, as well as titanium and other alloys, providing improved formability and weldability compared to the standard 304-grade stainless steel.

The alloy has a higher oxidation resistance when exposed to elevated temperatures and can be used in both hot and cold applications. Stainless Steel 321H Round Bars are often used in aircraft exhaust manifolds, chemical processing equipment, petroleum refining equipment, etc.

Applications:

- Aerospace(Piston Engine Manifolds)

- Chemical Processing

- Expansion Joints

- Food Processing(Equipment or Storage)

- Waste Treatment (Thermal Oxidizers)

- Pharmaceutical Production

- Petroleum Reining (Polythionic Acid Services)
