Stainless Steel 304L Pipes

Most Reliable SS 304L Seamless and Welded Pipe Stockist as per ASTM A312, Stainless Steel 304L Pipe Supplier in India


Stainless steel 304L pipe is a low-carbon version of 304, known for its excellent corrosion resistance, good weldability, and durability. It is commonly utilized in sectors, where cleanliness and strength are essential. Preston Pipes & Alloys is a trusted name in the stainless steel industry. They offer top-quality 304L stainless steel pipes that meet international requirements. The material contains key elements like carbon, manganese, silicon, phosphorus, sulfur, chromium and nickel. These elements provide the pipe with strength and corrosion resistance. Its mechanical qualities include a yield strength of 170 MPa, tensile strength of 485 MPa, hardness of 201 HB, and elongation of 40% making it appropriate for demanding applications.


304L stainless steel pipe resists rust in many environments including mild acids, and chemical agents. The low carbon content reduces carbide precipitation during welding. This is ideal for applications including food processing, chemical tanks, water treatment, and oil and gas systems. The pipe also works well in heat exchangers and pharmaceutical equipment. Its ability to hold up in both high and low temperatures adds to its versatility across sectors.
