Preston Pipes & Alloys is a trusted 904L Stainless Steel Tube supplier. These tubes are made from austenitic stainless steel known for strong resistance to acids and corrosion. Stainless steel 904L contains elements like carbon, chromium, copper, manganese, molybdenum, nickel, phosphorus, and sulfur. This mix gives it excellent strength and durability. It shows a minimum tensile strength of 490 MPa and a yield strength of 220 MPa. Its typical hardness ranges between 70 and 90 on the Rockwell B scale, making it ideal for both industrial and commercial use.
SS 904L tubes work well in high-temperature environments. SS 904L tubes perform well in high-temperature environments. These tubes have a melting point of 1350°C and a density of 8.05 g/cm³, making them suitable for temperatures ranging from 850 to 1150°C. They can withstand corrosion in harsh environments such as marine, chemical, and gas processing facilities. ASTM B677 UNS N08904 tubes are widely used in boilers, heat exchangers, construction, oil and gas pipelines, and other industrial applications.
We offer AISI 904L tubing in various forms and sizes to match different needs. ASTM A269 N08904 seamless tube sizes range from 3.00 mm to 219.10 mm in diameter, with wall thicknesses between 0.40 mm and 12.70 mm, and lengths up to 12 meters. SS 904L welded tube sizes range from 6.35 mm to 114.3 mm in diameter, with thicknesses up to 12.7 mm and lengths up to 26 meters. Available finishes include annealing, pickling, bright, and polished. These tubes come in round, square, rectangular, coil, U-shape, hydraulic, and honed forms to suit different applications.
Every 904L stainless steel tube goes through strict quality checks and tests to meet international standards like ASTM B677 / ASTM SB677. We inspect dimensions, pressure ratings, and material strength. Tubes are packed securely using standard wrapping and wooden boxes for safe delivery. As a reliable 904L stainless steel tube stockist, we make sure your orders arrive on time and ready for use. Get high quality ASTM B677 UNS N08904 tubes that meet your project needs.
