This grade is commonly known as “18-8” stainless steel, as it contains 18% chromium and 8% Nickel. 304 stainless steels are widely used to resists ordinary rusting in most applications. Both grades 304 and 304L can be made available seamless pipes and welded pipes form. We mainly have ready stock of 304/304L pipes. Grade 304L is widely used by the fabrication industry and all standard welding techniques can be used on 304L pipes. The “L” in 304L stands for “Low Carbon Content”, indicating a maximum carbon content of 0.035%. The “H” in 304H stands for “High Carbon Content”, indicating carbon content of not less than 0.04% and not more than 0.10%.
The tensile and yield strength of 304H stainless steel is greater than 304L, as the higher carbon content increases its strength. Stainless steel 304H grade pipes are widely used for manufacturing boilers, pressure vessels and heat exchangers for fertilizer plants, chemical plants, petroleum refineries, and power generation plants.
Stainless Steel 304/304L pipes and tubes are available in both seamless and welded form in OD and NB sizes. In addition to standard sizes, which are available in stock, our specialty is to manufacture and supply custom size 304/304L cold drawn seamless tubes from our factory.
Stainless Steel 304/304L pipes and tubes can be offered in random lengths of up to 6meters long or cut to a specific length as ordered. We also offer a complete range of stainless steel 304/304L butt weld fittings including 304/304L elbow, 304/304L bends, 304/304L tees, 304/304L reducers and caps.
