ASTM A312 TP304 Stainless Steel SS
A312 Tp304 tube is pushed or pulled to form a shape usually formed from a round billet of raw material. It is more corrosion resistant than ordinary 304 stainless steel pipe. Our 304 stainless steel seamless tube has a low carbon content， making it highly weldable and formable. Stainless steel 304 welded pipe can be in different shapes such as SS 304 round pipe or SS 304 square pipe. SS 304 Erw tube is used for long service chemical and industrial applications. There are different schedules such as the SS 304 Sch 40 pipeline. Our products are of high quality and have very competitive prices in the market.
If you are looking for one of the reliable 304 stainless steel pipe suppliers who can supply mirror polished pipe flat/beveled/threaded material， please check our customer and price list. TONG CHUANG GROUP supplies SS 304 from 6" NB to 120" Nb， including all types of seamless， ERW， welded， fabricated and grooved. All our materials are ASTM A312， A249 and ASME SA 312 International Specifications. We can supply 304 steel pipe thickness from 1.2mm to 2mm. Pipe lengths are standard sizes 3m， 6m and 10m. But we are one of the suppliers that offers grade 304 cut-to-length pipe， saving you cost and avoiding Waste.
