304 Stainless Steel Round Bar

304 Stainless Steel bar stock is a chromium-nickel austenitic stainless steel and is considered to be the most versatile and widely used stainless steel. 

The 304 Stainless Steel was previously known as 18-8 Stainless steel due to its chemical composition which consists of 18 percent chromium and 8 percent nickel.

However, 18-8 stainless is now just a form of the 304 Stainless Steel as this type of steel continues to evolve to accommodate the specifications of the necessary applications in various industries. 

As such, the nickel content of the 304 Stainless Steel makes it an austenitic one and gives it its tough and ductile structure allowing it to be easily formed and fabricated. On the other hand, its chromium content takes care of providing a protective layer over it, preventing the oxygen from penetrating the surface of a 316 304 Stainless Steel bar stock and preventing it from rusting.

Consequently, despite the remarkable similarities between 304 and 304L Stainless Steel, there is still one significant difference between the two and that’s their carbon content. 

304 Stainless Steel has a roughly 0.04% higher carbon content than 304L similar to that of the 316 and 316L Stainless Steel.

304L Stainless Steel Bars Versatility

Though grade 304L is an extra-low carbon version of the 304 alloys, it is still used widely as it is also versatile. The lower carbon in 304L stainless steel helps to minimize harmful carbide precipitation due to welding. The alloy helps improve weldability.
