304 Stainless Steel Pipes, 304 Stainless Steel Tubes, 304 Stainless Steel Seamless Pipe & Tubes, 304 Stainless Steel Welded Pipes and Tubes, 304 Stainless Steel Tubing, UNS S30400 Pipes and Tubes, 1.4301 Stainless Steel Pipes & Tubes manufacturer.
304 is a general-purpose stainless steel, widely chosen for applications needing both corrosion resistance and formability. To achieve this, it must contain over 18% chromium and 8% nickel.
Grade 304 Stainless Steel Pipes are the most flexible and commonly used stainless steel grade on the market. Stainless Steel 304 grade is the most commonly used alloy in the industry. Stainless Steel 304 Welded Pipes have a high mechanical strength because of their duplex microstructure and nitrogen alloying.
Stainless Steel Pipe 304 has excellent mechanical properties and resistance to many corrosive agents. Nonmagnetic in the annealed condition. Cold working increases hardness and tensile strength, while reduced carbon content modifies these properties to provide good resistance.
Jinie Technology offers Stainless Steel 304 Pipes/Tubes in a variety of standards, sizes, and shapes, including round, square, rectangular, and hydraulic types. The Stainless Steel 304 Welded Pipe is made by welding a thin strip or sheet together. Jinie Technology (Jiangsu) Co., Ltd. is a leading provider of ASTM A312 TP 304 stainless steel pipes and tubes.
