304 Seamless steel pipe
304 seamless pipe has no sand holes, no sand holes, no black spots, no cracks, smooth weld. Bending, cutting, welding processing advantages, nickel content stable advantages.304 seamless pipe is resistant to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosive medium corrosion steel pipe. Also known as stainless acid - resistant steel pipe.
The corrosion resistance of 304 seamless tube depends on the alloy elements contained in the steel. Chromium is the basic element to make stainless steel corrosion resistance. When the chromium content in steel reaches about 12%, chromium and oxygen in the corrosive medium react to form a very thin oxide film (self-passivation film) on the steel surface, which can prevent further corrosion of the steel matrix. In addition to chromium, stainless steel seamless tube commonly used alloy elements and nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses of stainless steel structure and performance.
304 seamless pipe is a hollow circular steel strip, widely used in petroleum, chemical, medical, food, light industry, mechanical instrument and other industrial pipeline and mechanical structure components. In addition, in the same bending, torsional strength, light weight, so it is also widely used in manufacturing machinery parts and engineering structures. Also commonly used for the production of conventional weapons, gun barrels, shells and so on.

304 Seamless steel pipe Equivalent Material
The thicker the wall thickness of 304 seamless tube, it is more economical and practical, the thinner the wall thickness, its processing cost will rise greatly;304 seamless tube process determines its limited performance, general seamless steel pipe precision is low: uneven wall thickness, low brightness inside the tube surface, the cost of size is high, and the inner surface and pitting, black spots are not easy to remove;
304 seamless tube detection and shaping must be offline processing. Therefore, it has its advantages in high pressure, high strength and material for mechanical structure.
