With stainless steel tube and hose connec-tions made from free cutting steel, the collar is less due to the harder material. During assembly, it is absolutely essential that the tube is held firmly against the stop in the inner cone of the fitting; if not, the

PRACTICAL HARDNESS TESTING MADE SIMPLE if the tested material is too thin (less than 9.6 mm or 3/8 ") so that a mark appears on the opposite side if the tested material is too hard (more than 450 HBS for steel ball or more than 650 HBW for tungsten carbide ball). The letters HBS stand for Hardness Brinell with Steel ball, (HBW for tungsten carbide ball) but the qualification Selecting Materials for Punching and Forming Tools and Cutting The cutting surfaces of the punch and cutting plate penetrate the sheet to be cut, initially deforming it elastically and later plastically in the shear zone. When the deformability of the material to be cut is exceeded, fine cracks form at first which spread out and expand as cutting contin-ues. Eventually the material fractures and

    Plasma Cutting. This method of cutting the metal material is ideal for mild steel plates. Whatever this method lacks in terms of the quality of the edges cut, it makes up for speed. There is an increasing possibility that the edges will lack the ideal squareness when the metal materials are significantly thin or Structural Shapes - Nucor-Yamato SteelNucor-Yamato Steel or refer to the regularly published Proposed Rolling Schedule to determine the current rolling frequency.
