Stainless Steel 321H Square Pipes

321H stainless steel Square Pipe is composed of mainly iron, chromium, and nickel. The major alloying elements in the pipe are chromium (16-18%), molybdenum (3-5%), and nickel (8-10%). Other alloying elements such as manganese, silicon, and vanadium can also be present depending on the grade. Chromium increases corrosion resistance, tensile strength, and resistance to oxidation at high temperatures while nickel improves formability and toughness. Molybdenum increases hardness, strength, and thermal stability while silicon enhances weldability. Additionally, vanadium helps improve the toughness and ductility of the square pipe.

SS 321H Square Pipe is a high alloy austenitic stainless steel commonly used for applications such as automotive parts, tubing, pressure vessels, and chemical processing. The pipe is known for its excellent corrosion resistance in both acidic and alkaline environments and its superior strength in comparison to other steels. Furthermore, the alloy's superior oxidation resistance at high temperatures allows it to be used in many heat-treating processes. Its strength and ductility make it an ideal material for structural components like beams and supports while its low thermal conductivity increases its use in applications that require slow cooling rates. Additionally, 321H stainless steel square pipe has excellent creep resistance making it suitable for highly strained components where other alloys would fail prematurely.
