One of the best SS 304 box tube supplier in India

Stainless steel rectangular tubing

Stainless steel alloys are broadly categorised into four classes, with the austenitic class being the most prevalent. Because stainless steel alloys have an FCC (Face centre cubic) microstructure. FCC microstructure alloys are typically packed very closely together. Because the crystals are so close together, the alloy is more ductile. Because the alloy has a higher amount of ductility, it may be formed into odd shapes such as Stainless Steel Rectangular Tubing.

Exporter of high-quality ss 304 rectangular tube, providing efficient shipping and delivery services to meet global demand

Because the tubing requirements for each alloy varied, so do the grades used to create them. Additionally, the Stainless Steel Rectangular Tubing Dimensions used to manufacture said tubing will differ. The dimensions will also include the thickness of the wall, the length, and the diameter or circumference. The most commonly used Austenitic classes are grade 304 and class 316. While grade 304 Stainless Steel Rectangular Tube is the most cost-effective option, grade 316, often known as marine grade steel, is a more robust option. The inclusion of molybdenum in the alloy of Stainless Steel Rectangular Tubing 316 results in an improvement in strength.

The addition of molybdenum to an alloy improves the material’s characteristics. For example, the alloy for grade 316 Stainless Steel Rectangular Tube would be more resistant to pitting and crevice corrosion than grade 304.
