SS 321 Round Bar

Stainless Steel 321 Round Bar

The Stainless Steel is an alloy that can be used in any application in the world. The alloy is made up of number of significant metals like Chromium, Carbon, Nickel, Molybdenum, etc. these are the metals that instil their own property into the alloy and making it the best. Forming stainless steel out of all these metals is very useful as it is a stronger metal than others and very much resistant to corrosion and pitting to many substances and conditions and climates.

Stainless Steel is an alloy made up of certain materials like Chromium up to 18%, Carbon 0.8%, Manganese 2%, Nickel 8%, Silicon, Molybdenum, etc. in certain proportions. The alloy has many grades derived from itself and they are- SS 304, SS 304L, SS304H, SS 316, SS 316L, SS 316H, SS 317, SS 317L, SS 32L, SS 32LH, SS 408, SS 409, SS 410, SS 416, SS 420, SS 430, SS 440, SS 630, etc. All these grades are different from each other. The difference is mainly in chemical properties some might have more chromium or some less, same goes with other metals which are more or less in Stainless Steel grades.

Stainless Steel 321 grade

The Stainless Steel 321 is a type of grade that has Chromium between 17-19%, Carbon at 0.8% which makes it stronger Nickel is more than usual between 9-12%, and Manganese at 2% and Titanium in a certain ratio. The mechanical properties of grades 321 are Tensile Strength 75000, 515; Yielding Strength 30000, 205; Elongation at 40%. The SS 321 is a stabilized alloy with the addition of titanium which is not available in any other SS grade.

The general storage is done in the form of round bars, pipes, tubes, sheets, coils, fittings, etc. What makes grade 321 different from other grades is that it has titanium in itself which is not the case with other grades. Titanium makes the grade 321 stabilized and suitable for work.

For applications in the range of temperatures up to around 900 degrees C, Stainless Steel 321 is the grade of choice, combining high strength, scaling resistance, and phase stability with corresponding aqueous corrosion resistance. SS 321 Bars have excellent forming and welding properties, and can be easily brake or roll-formed.

They also have excellent welding characteristics and durability, even at cryogenic temperatures. In the 425-900 ° C range, SS 321 performs well, especially in the presence of corrosive aqueous conditions. SS 321 is used because it is resistant to intergranular corrosion after carbide precipitation at temperatures ranging from 425-850 degrees C.

SS 321 Round Bars and Applications

A round bar is a piece of metal that is long and round in shape. The metal is first melted and softened and is then cooled and rolled continuously to keep the shape intact and make it hard. The round bars come in all sizes right from length to width some manufacturers even offer the choice of customization.

The SS 321 Round Bars are mostly used in applications like De-aerating heaters, Marine engineering, Chemical and hydrocarbon processing equipment, Gasoline and, freshwater tanks, Boiler feedwater heaters and other, heat exchangers, Valve, pumps, shafts, fittings, and fasteners, Industrial heat exchangers, Crude petroleum stills, Chlorinated solvents, Crude oil distillation towers. All these mentioned industries rely heavily on stainless steel 321 as it is an alloy that has the ability to withstand the harsh conditions and temperatures of the industries.

This alloy is also stronger so generally it is meant to be used for such utilities. These are just some uses of a SS 321 round bar it serves a lot of purposes.
