Product description

304 Seamless Pipe

304 Seamless pipe with no sand hole, no holes, no black spots, no cracks, welding path formation. Bending, cutting, welding processing performance advantages, nickel content stability advantages.


Corrosion Resistance 

304 Seamless pipe is resistant to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical etching of the corrosion of medium steel pipe. Also known as rust-proof steel pipe.


The corrosion resistance of 304 seamless tubes is determined by the alloying elements contained in the steel. Chromium is the basic element of stainless steel to obtain corrosion resistance, when the chromium content in steel reached 12% or so, chromium and corrosive medium of oxygen in the steel surface to form a thin layer of oxide film (self passivation film), can prevent further corrosion of the steel matrix. In addition to chromium, stainless steel seamless tube commonly used alloy elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the various uses of stainless steel microstructure and performance requirements.


304 Seamless pipe is a hollow round steel, widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical components. In addition, the bending, torsional strength of the same, light weight, it is also widely used in the manufacture of mechanical parts and engineering structures. Also used for the production of various conventional weapons, barrels, shells and so on.


304 Seamless pipe wall thickness thicker, it will be more economical and practical, the thinner the wall, its processing costs will be greatly increased;


304 Seamless pipe technology to determine its limitations can, general seamless steel tube precision Low: uneven wall thickness, the appearance of low brightness in the tube, the high cost of the fixed ruler, and inside the appearance of hemp spots, black spots are not easy to remove;

304 Seamless tube inspection and shaping must be off-line processing. Therefore, it embodies its superiority in high pressure, high strength and mechanical structure.
