304 Stainless Steel Alloy

304 Stainless Steel Alloy

304 Stainless Steel Alloy is similar to 302 Stainless Steel Alloy in terms of its corrosive, oxidation, and forming traits as well as its physical and mechanical abilities. 304 is a low carbon version of 302, or better known as 18-8. Its lower concentration of carbon makes it slightly weaker than 302 when in the annealed condition. 304 Stainless Steel Alloy has useful applications in welding because its reduced carbon footprint allows it to withstand some carbon precipitation (between 800-1500 degrees Fahrenheit), without the need for post-annealing assistance.
Stainless Steel 304L has less carbon versus the regular 304. The “L” in its name refers to the “low carbon content.” This alloy can be used in the welded form without being susceptible to intergranular corrosion. After the welding process, Stainless Steel 304L may require annealing due to the corrosive nature of the process.
