321 Stainless Steel Coil

Our 321 Stainless Steel Coil shows extra protection from intergranular corrosion due to its stabilized austenitic structure. Titanium is added to this grade to avoid chromium carbide forming during welding or heating processes, so it is suitable for uses where metal parts must remain exposed to heat for a long time. Due to its good oxidation resistance and favorable mechanical properties at high temperatures, the 321 Stainless Steel Coil is commonly used in the aerospace industry, chemical facilities and for exhaust systems. Our Stainless Steel Coil Products offer this grade, which delivers dependable results thanks to thermal stability and corrosion resistance. This coil from Foursteels comes in several finishes, widths and thicknesses to help meet the needs of many industries. Order yours today!

Parameter

Features and Applications of 321 Stainless Steel Coil

Chromium, nickel and titanium make up 17–19% of 321 Coil Steel, supporting resistance to sensitization. Because of this makeup, the material is able to resist cracks due to stress and harsh conditions at high temperatures. It is outstanding in places where the temperature may reach up to 900°C (1650°F).

Many industries depend on metallic expansion joints for aircraft exhausts, expansion joints, heat exchangers and chemical manufacturing equipment. You can repeatedly heat and cool the 321 Stainless Steel Coil without it getting weak or corroding. Because of its good weldability and formability, it can be used to produce many detailed shapes.

·Tube Shapes. Depending on the grade of stainless steel selected, we supply tubing in rectangular, round, and square shapes.
