Schedule 40 304 Stainless Steel Pipe 1/2 Inch ASTM A312 Stainless Steel Tube
Stainless Steel Pipes 304 1/2in Sch40, ASTM A312, Corr-Resistant, Plumbing & Food Processing
Stainless Steel Pipes 304 (1/2" Sch40) are precision-engineered for demanding applications in plumbing systems, food processing, and chemical industries. Manufactured under ASTM A312, these pipes combine superior corrosion resistance, hygienic properties, and structural durability. The 304 grade, with its balanced chromium (18–20%) and nickel (8–10.5%) content, resists oxidation, chloride stress cracking, and organic acids, making it ideal for transporting water, steam, and food-grade fluids. The 1/2" Sch40 dimension ensures optimal pressure handling (up to 483 psi at 100°C), while the smooth internal surface minimizes contamination risks in sanitary environments.
