304 Stainless Steel Pipe is the standard “18/8” stainless steel; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless steel part such as sink, hollow-ware and saucepan. For these application it is common to use special “304DDQ” (Deep Drawing Quality) variants. Grade 304 Pipe is readily brake or roll formed into a variety of components for application in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristic. Post-weld annealing is not required when welding thin sections. Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge component (over about 6mm). Grade 304H with its…

Zhejiang Guanyu Stainless Steel Tube Co., Ltd is specialized manufacturer of 316L Stainless Steel Tubes according to ASME SA 213 / ASTM A 213, 316L Stainless Steel Tube are molybdenum-bearing austenitic stainless steel, which are more resistant to general corrosion and pitting corrosion, crevice corrosion than the conventional chromium-nickel austenitic stainless steel such as 304. 316L Stainless Steel also offer higher creep, stress-to-rupture, and tensile strength at elevated temperature. In addition to excellent corrosion resistance and strength properties, the Alloys 316 and 316L Cr-Ni-Mo alloys also provide excellent fabricability and formability which are typical of the austenitic stainless steel. 316L Stainless Steel Tubes is improved version of 304 Stainless Steel, with the addition of molybdenum and higher nickel content. The resultant Chemical composition of 316 gives the steel much increased corrosion resistance in aggressive environment. Molybdenum make the steel more resistant to pitting and crevice corrosion in chloride-contaminated media, sea…

ASME SA213 TP304L Stainless Steel Tube is a variation of the 18% chromium – 8% nickel austenitic alloy, the most familiar and most frequently used alloy in the stainless steel family. This alloy may be considered for a wide variety of applications and exhibits good corrosion resistance, ease of fabrication, excellent formability, and high strength with low weight. Type 304L is a lower carbon variant of Grade 304 – the steel can be welded without the resulting issue of carbon precipitation precipitation of chromium carbide as heat is applied during the welding process which depletes the chromium element of the steel thus reducing its anti-corrosive/oxidation effectiveness, and because of low carbon percentage, can minimizing Intergranular corrosion attack. As a result, Type 304L Stainless Steel Tube is a sort after material for use in severely corrosive conditions. Weld annealing is only necessary in applications where stress loads are excessive. This steel Grade is found in a variety of commercial sectors, particularly in the chemical industry. 304 &…
