Square stainless steel pipes and tubes have been one of the most important substances that are used in umpteen manufacturing processes and construction works. Amongst square stainless steel, one of the most versatile types is the stainless steel 304 (SS 304). It is made up of 18% chromium and 8% nickel, which gives it its characteristic stainless look and helps to resist corrosion. While industries prefer this over other stainless steels, what they cannot pick easily is its manufacturer and supplier. In this blog, Sigma Steel Pipes will be telling you about the best supplier for SS 304 hollow pipes and tubes. So, without any further ado, let’s get started:
What is SS 304?
Stainless steel square pipe get their names from the American Iron & Steel Institute (AISI) and the Society of Automotive Engineers (SAE), who have separately created their own naming systems for steel alloys based on alloying elements, uses, and other factors. Steel names can get confusing, as the same alloy can have different identifiers depending on which system is used; however, understand that the chemical composition of most alloy blends remains the same across classification systems. In the case of square steel pipes, they are often composed of 10 to 30% chromium and are made to withstand varying degrees of corrosion exposure. To learn more about the differences among stainless steel, feel free to read our article on the type of stainless steel.
The Type 304 steel is part of the 3xx stainless steel square pipe or those alloys which are blended with chromium and nickel. Apart from these two elements, it has carbon, chromium, iron, manganese, nickel, phosphorus, sulfur, and silicon. The density of 304 steel is around 8 g/cm3. Type 304 steel also comes into three main varieties:
- 304
Here, the carbon content is between 0.08%. Type 304 steel is austenitic, which is simply a type of molecular structure made from the iron-chromium-nickel alloy blend. It makes 304 steel essentially non-magnetic and gives it a lower weakness to corrosion between grains thanks to austenitic steels being generally low carbon. 304 steel welds well using most welding methods, both with and without fillers, and it easily draws, forms, and spins into shape.
