Stainless Steel 321 Plates Supplier

What is SS 321 Plates

Universal Metal Corporation is synonymous with excellent quality, and we work hard to preserve that reputation via the manufacturing a premium quality of Stainless Steel 321 Plates. With our trained staff & workers working around the clock to ensure that our plates are made precisely and that factory facility is maintained in accordance with the requirement.

321H stainless steel plates are basic austenitic materials. Titanium is added to certain grades to stabilize them. These grades are frequently used in applications requiring temperatures of up to 1,650 ° F. These plate grades combine excellent strength, scaling resistance, and phase stability with resistance to subsequent aqueous corrosion. Because 304L plate is more widely available in most product shapes, it is typically preferred over 321 if the only need is resistance to intergranular corrosion after welding. However, because 304L has a lesser heat strength than 321 and 321H plates, it may not be the ideal choice if the need is resistance to an operational environment greater than 932 degrees Fahrenheit.

The quantity of carbon present inside each metal determines the difference between SS 321 and 321H grades. 321 has no more than 0.08 percent carbon, whereas 321H contains between 0.04 and 0.10 percent carbon. They both have a maximum manganese content of 2.0 percent, 0.75 percent silicon, and 0.045 percent phosphorous. The inclusion of titanium provides 321 and 321H stainless steel plates its distinct characteristics.

These Stainless Steel 321 and 321H Plates are used in several industrial sectors like aerospace sector, particularly in airplane exhaust and piston engine manifolds. These grades have used in the petrochemical & food handling sectors, particularly in machinery and storage. These grades are also used in petroleum refining, the chemical sector, and waste treatment operations.
