Harsh Metalloys, based in Mumbai, India, is a well-respected manufacturer and supplier of top-notch Stainless Steel 304L Bars. These bars are made from low-carbon 304 stainless steel, which provides outstanding corrosion resistance, weldability, and strength. They’re perfect for applications that require welding without the worry of carbide precipitation. You’ll find 304L bars used in various industries, including chemical processing, food and beverage, marine, and pharmaceuticals. Harsh Metalloys offers these bars in different sizes, shapes (like round, square, and hex), and finishes, all crafted to meet international standards such as ASTM A276 and ASTM A479, ensuring top quality and reliability.
Stainless Steel 304L Bars are composed of Chromium (18–20%), Nickel (8–12%), Carbon (≤0.03%), Manganese (≤2%), Silicon (≤1%), Phosphorus (≤0.045%), and Sulfur (≤0.03%). The low carbon content boosts weldability and minimizes the risk of intergranular corrosion. In terms of mechanical properties, they have a tensile strength of about 485–515 MPa, yield strength around 170–205 MPa, elongation of roughly 40%, and a maximum hardness of 90 HRB. These characteristics, along with excellent corrosion resistance and good formability, make 304L bars ideal for a wide array of structural and mechanical applications.
