  The stainless steel reducer is a kind of pipe fittings used at the pipe diameter change. Usually, the stainless steel reducer forming process is shrinkage pressing, expanding pressing or shrinkage and expanding pressing. Stamping forming can also be used for some size stainless steel reducer. The stainless steel reducer are characterised by carbon steel with significantly higher strength than the same carbon content, good toughness and plasticity, as well as good weldability and corrosion resistance. The shrinkage forming process of the stainless steel reducer end is to put the pipe blank with the same diameter as thestainless steel reducer end into the forming die, and make the metal move and shrink along the die cavity by pressing along the axial direction of the tube blank.

  According to the size of the ASTM A312 TP304L Stainless Steel Pipe Fittings Reducer it can be divided into one pressing forming or multiple pressing forming. Diameter enlargement is formed by using a blank smaller than the diameter of the large end of the pipe with an internal punching die along the inner diameter of the pipe blank. The expanding process mainly solves the problem that the larger size stainless steel reducer is not easy to be formed by shrinking. Sometimes, according to the stainless steel reducer need of material and product forming, the expanding and shrinking methods are combined.
