Stainless Steel 304H Round Bar

SS 304H Round Bars Manufacturers, ASTM A276 304H, Stainless Steel Round Bar, SS 304H Round Bars Suppliers, SS 304H Round Bars Stockist in Mumbai India.


Stainless Steel 304H Round Bar is a high-carbon version of 304 stainless steel, designed for better strength at high temperatures. It is well-known for its high corrosion resistance and durability making it perfect for use in harsh situations. Preston Pipes & Alloys is a leading name in the metal industry, providing high-quality bars that meet global requirements. The grade contains up to 0.10% carbon, 18–20% chromium, and 8–10.5% nickel, providing strong resistance to oxidation and scaling. The material has a density of 8.0 g/cm³, a melting point of 1400°C, tensile strength of 515 MPa, yield strength of 205 MPa, and 40% elongation for increased formability. This combination of chemical balance and mechanical performance makes it reliable for critical applications.


We offer bars in a variety of sizes and diameters to meet various needs. They come in diameters from 0.1 mm to 100 mm, sizes from 5 mm to 500 mm, and lengths from 100 mm to more than 3000 mm. We use various manufacturing techniques to ensure precision and consistency, whether in black, bright polished, rough turned, No.4 finish, matt finish, or BA finish. The versatility in dimensions and surface finishes makes Stainless Steel 304H Bar adaptable for both structural and high-temperature uses.


SS 304H Round Bar

Stainless Steel 304H Round Bar offers strength retention at elevated temperatures and excellent corrosion resistance. These characteristics make it a popular option for steam exhausts, pipelines, cooling towers, boilers, heat exchangers, condensers, and petroleum refineries. It is also used in electric power plants, as well as fertilizer, and chemical factories. The ability to handle heat and pressure provides, dependability in severe industrial environments.


Every bar undergoes strict quality checks and testing in line with ASTM B166 / ASME SB166 standards. This includes dimensional inspection, mechanical testing and surface quality tests. We provide packaging that employs secure ways to prevent damage during transportation such as protective materials and safe handling. Stainless Steel 304H Round Bar is a preferred solution for high-performance applications because of its consistent quality and reliable supply. Choose us for premium-grade material to ensure strength, durability, and long service life in your projects.
