304 Stainless Steel Pipes and 304L Stainless Steel Tubes is commonly known as “18-8” stainless steel, as it contains 18% chromium and 8% Nickel. SS 304 Pipes are widely used to resists ordinary rusting in most applications.
Both grades, UNS S30400 and UNS 30403, can be made available seamless pipes and welded pipes form. Grade Stainless Steel 304 Tubes, Stainless Steel 304 Pipes is widely used by the fabrication industry and all standard welding techniques can be used on SS 304L ERW Pipes. The “L” in Stainless Steel 304L Welded Pipes stands for “Low Carbon Content”, indicating a maximum carbon content of 0.035%.
Meanwhile, our 1.4301 Pipes and 1.4307 Tubes are widely used for manufacturing boilers, pressure vessels and heat exchangers for fertilizer plants, chemical plants, petroleum refineries, and power generation plants. In addition to standard sizes, which are available in stock, our specialty is to manufacture and supply custom size of Stainless Steel ASTM A312 TP 304 cold drawn seamless tubes, Stainless Steel 304l Pipes & Stainless Steel 304l Tubes from our factory.
