With 20 years of experience, Ningbo Huali Steel Co., Ltd is a top manufacturer of 321 cold rolled precision stainless steel coil in China. We specialize in producing a wide range of cold-rolled precision stainless steel products, including coils, strips, foils, and sheets as well as FeCral alloy, Titanium.
321 cold rolled precision stainless steel coil is an austenitic stainless steel. Different standards include SUS 321, EN 1.4541, AISI 321, and DIN 1.4541. 321 belongs to the category of heat-resistant steels, with superior high-temperature resistance compared to 316L. The Ti in it serves as a stabilizing element. 321 cold rolled precision stainless steel coil exhibits good corrosion resistance in organic and inorganic acids of varying concentrations and temperatures, especially in oxidizing media. It is commonly used for manufacturing corrosion-resistant acid containers, linings of corrosion-resistant equipment, and transportation pipelines.

321 cold rolled precision stainless steel coil possesses corrosion resistance, high temperature resistance, and creep resistance. Its properties are very similar to those of 304, but the addition of titanium metal provides it with better resistance to intergranular corrosion and higher temperature strength. The incorporation of titanium effectively controls the formation of chromium carbide.
Compared to 304, 321 cold rolled precision stainless steel coil exhibits better stress rupture performance and creep resistance at high temperatures. It is suitable for welded components that are used at elevated temperatures.
Application: combustion pipes of petroleum waste gas, engine exhaust pipes, boiler shells, heating exchangers, furnace components, muffler parts for diesel engines, flexible metal pipes, and more.
