Steel Round Solid Shaft ASTM A276 Scm440 42CrMo4 SAE AISI 4140 En19 1.7225 High Tensile Hot Rolled Steel Round Bar Steel Bar

Cold drawn steel bar is made from special quality hot rolled steel bar. It is drawn through a die reducing the cross-sectional area of the bar and giving it a smooth surface.

• Shapes: According to the shapes of the die, the finished product can get a round, hexagonal, square, flat and other cross section.
• Advantage: Cold drawn bars have greater size accuracy, straightness and increased tensile and yield strength as well as improved machinability.
• Further processing: In addition to standard cold drawn steel bars. It can also be polished or ground to get better surface.
• 1.used for welding structural parts: such as oil pipelines, chemical equipment, Marine equipment, etc.2.used for processing all kinds of conventional parts and for stamping die;
  3.used as high precision mechanical parts of steel;
  4.used for the manufacture of medical instruments and food industry utensils and other requirements of non-toxic sanitation or sterile environment of the parts.
  5. It is widely used in the heat treatment process of stress relief annealing before bending.
