304 stainless steel tubes in the air or chemically corrosive media can resist corrosion of a high alloy steel, in order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium.
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.
There are many cold forming factors affecting 304 stainless steel, which are also very complicated. As far as its metallization factors are concerned, it is mainly the composition of steel, that is, the ratio of chromium equivalent to nickel equivalent, and the elongation in its conventional tensile properties is an important characterization index.
【Heat treatment Process】
304 stainless steel pipe solidification treatment temperature of 1080-1100 ℃, cooling mode for water-cooled or air-cooled. Cold processing intermediate annealing temperature is more than 850-970 ℃, insulation for a certain period of time after water cooling.
304 Stainless steel tubes inhibit carbide precipitation during welding and can be welded using a general method.
