304 cold drawn seamless steel pipe
304 cold drawn seamless steel pipe is resistant to air, steam, water and other weak corrosion medium and acid, alkali, salt and other chemical corrosion medium corrosion steel tube. Also known as stainless acid - resistant steel pipe.
The corrosion resistance of stainless steel seamless tube depends on the alloy elements contained in the steel. Chromium is the basic element to make stainless steel corrosion resistance, when the content of chromium in steel reaches about 12%, chromium and the oxygen in the corrosion medium, the formation of a very thin oxide film on the surface of steel (self-passivation film), can prevent the steel matrix further corrosion. In addition to chromium, stainless steel seamless tube commonly used alloy elements and nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the various USES of stainless steel structure and performance requirements.
Stainless steel seamless pipe is a hollow long round steel, widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transport pipelines and mechanical structural components. In addition, bending, torsional strength of the same weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also commonly used for the production of conventional weapons, barrels, shells, etc.
First, the thicker the wall thickness of stainless steel seamless tube, it is more economical and practical, the thinner the wall thickness, its processing cost will be greatly increased;
Secondly, stainless steel seamless tube technology determines its limited performance, the general seamless steel tube precision is low: uneven wall thickness, inner tube appearance brightness low, high ruler cost, and the inner appearance and pitting, black spots are not easy to remove;
Third, stainless steel seamless tube detection and shaping must be offline processing. Therefore, it embodies its superiority in high pressure, high strength and mechanical structure.It has the following production steps: a. Round steel preparation; B. Heating; C. Hot rolling piercing; D. Cutting head; E. Pickling. F. Grinding; G. Lubrication; H. Cold rolling; I. Degreasing; J. Solution heat treatment; K. Straightening; L. Pipe cutting; M. Pickling. N. Finished product inspection.
304 cold drawn seamless steel pipe are all made of imported first-class stainless steel plates, featuring: no sand holes, no sand holes, no black spots, no cracks, smooth weld. Bending, cutting, welding processing advantages, stable nickel content, products in line with GB, ASTM, JIS and other standards in China!
