Potable (Drinking) Water Tube
304 stainless steel pipes are among the most widely used stainless steel products globally, valued for their excellent corrosion resistance, durability, and versatility. As part of the austenitic stainless steel family, 304 pipes contain 18-20% chromium and 8-10.5% nickel, providing a strong balance of mechanical properties and resistance to oxidation, acids, and organic chemicals.
