304 stainless Steel Pipe has a good cold, thermal processing performance, can use a variety of general cold, thermal processing technology to produce forging materials, bars, wire, plate, strip and silk and other metallurgical products, thermal processing temperature range of 900-1180 ℃.
304 stainless Steel Pipe classification There are many kinds, first of all, seamless pipe and straight seam welded steel pipe, followed by the most basic classification is the structure with 304 stainless steel pipe and industrial fluid transport with 304 stainless steel pipe.
Hot rolling (extrusion seamless steel pipe):
Round tube billet → heating → perforated → three-roll oblique rolling, continuous rolling or extrusion → off-pipe → fixed diameter (or reduced diameter) → cooling → billet Tube → straightening → hydraulic test (or flaw detection) → mark → storage. Cold drawing (rolling) seamless steel pipe: round tube billet → heating → perforation → head → annealing → pickling → oiled (copper plating) → multi-Channel cold drawing (cold rolling) → Billet pipe → heat treatment → straightening → hydraulic test (flaw detection) → marking → storage.
【Heat treatment Process】
304 stainless steel pipe solidification treatment temperature of 1080-1100 ℃, cooling mode for water-cooled or air-cooled.
304 Stainless steel tubes inhibit carbide precipitation during welding and can be welded using a general method.
