The corrosion resistance of stainless steel elbow with the carbon content increases. Elbow characteristics: strength, toughness is the best variety of steel, the most prominent advantage is corrosion-resistant, corrosion than in the chemical and paper where the strong stainless steel must be used, of course, the cost is higher! The corrosion resistance of stainless steel with the increase of the carbon content decreased, so most volume low carbon stainless steel, the maximum not more than 1.2%, and some steel wC (carbon), and even less than 0.03% (as 00Cr12 ). Stainless steel is the main alloying elements Cr (chromium), and only when the Cr content reaches a certain value, only the corrosion resistance of steel. Therefore, stainless steel is generally Cr (chromium) content of at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, si other elements. Pipeline installation in a common connection with the pipe, nominal diameter connecting two identical or different tubes, pipes do make a certain angle turn. Using drawing and punching elbow on technical and economic advantages of hot stamping and drawing elbow manufacturing method is in the general manufacturing pipe bender has the following advantages: the radius of curvature is equal to D can be manufactured as well as 1.5D elbow , which is made by other methods than the pipe; elbow on any cross section are maintained properly and wall thickness in the circumferential circle; in any desired direction, the possibility of rotation. For punching or pulling elbow workers, comparing the normal elbow bending machine manufacture the required low level of technology. Hot stamping method and compared with the following bit of drawing method: minimum labor manufacturing process; energy system out with straight pipe section and a relatively thick wall elbow; scrap rate is small (rupture, folds, etc.). Based on the above information and comparison of production practices proved fully explain the law and punching stainless steel elbow making seamless elbow drawing method is the more complete method.
