Tricon Steel & Alloys is India's largest supplier, dealer, and manufacturer of Stainless Steel 321 / 321H Sheets, Plates, and Coils. These Products are alloys known for exceptional corrosion resistance and high heat resistance. Made primarily of chromium and nickel and added titanium, this alloy exhibits excellent resistance to intergranular corrosion, making it stronger as a chemical, air, and road agent. Their high carbon content allows them to withstand high creep resistance at elevated temperatures and is ideal for use in harsh environments such as power generation.
An important feature of SS 321H Sheets is its ability to withstand temperatures up to 1500 (816 °C) for extended periods without significant degradation during operation. This makes it suitable for high-temperature applications in continuous operations, such as heat exchangers, Furnace parts and exhaust systems. Moreover, their excellent weldability and formability make them easy to manufacture in various materials and structures, allowing versatility in design construction.
Table Of Content
SS 321 Plates undergo strict testing to ensure their properties and performance characteristics meet industry standards. Typical tests include chemical reagents, mechanical tests, and nondestructive testing. Chemical analysis confirms alloy composition and ensures the presence of major elements such as chromium, nickel, and titanium in specific ranges. Machine testing measures tensile strength, yield strength and expansion properties to ensure the material meets technical requirements for specification and is never used with any internal errors or discrepancies or is known to impair the integrity of the contents.
SS 321H sheets, plates and coils are used in various applications, including aerospace, chemical processing and power generation. Aerospace manufacturers manufacture aircraft components, such as aircraft leaks and engine parts, used in hot environments, such as reactors, vessels and pipelines. In addition, they are used in boilers, heat exchangers and turbine components in power plants, where they can withstand extreme temperatures and corrosive winds.

Reheating Furnace
A reheating furnace is a crucial component in the steel manufacturing process, particularly for hot rolling mills where sheets or slabs are heated prior to rolling.
Scale Breaker
A scale breaker, also known as a descaler, is a piece of equipment used in the steel manufacturing process to remove scale from the surface of hot-rolled steel products. Scale refers to the iron oxide layer that forms on the surface of steel when it is heated to high temperatures during the manufacturing process.
Finish Rolling
Finish rolling, also known as final rolling, is the last stage in the hot rolling process of steel or other metals. It involves reducing the thickness of the material to its final desired dimensions and achieving the required surface finish.
Skin Pass Mill
A skin pass mill, also known as a temper mill or a rolling mill, is a specialized type of rolling mill used in the steel or metal industry to improve the surface finish and mechanical properties of cold-rolled steel coils or sheets. It operates after the cold rolling process and before further processing or coating.
