It is used where ductility and softness are important and high tensile strength is not required. These are tough but not resistant to wear, since these are soft, can be very easily formed and later can be carburized to increase the hardness and wear resistance. Low-carbon steels are used for such operations as spinning, cold bending, rivetting, swaging, etc. These are not responsive to normal heat treatment but for case hardening. They form the largest percentage of steel produced, being the cheapest engineering material. Products such as screws, nails, nuts, bolts, washers, wire fences, light and heavy structural members, machine parts, forged parts can be made from low-carbon steel. It is also used for tin plate and automobile body sheet. It is available in form of sheets, squares, rounds, plates, and wires. Medium Carbon Steel They are less ductile but harder and have greater tensile strength than low-carbon steels. They also have better machining qualities and are more responsive to heat treatment. These are widely used in the industry. Medium carbon steels are used for making shafts, connecting rods, spindles, rail axles, gears, turbine bucket wheels, steering arms and other machine ... 目录: 出版说明 序 Preface 1 Introduction Objectives 1.1 Manufacturing Processes 1.2 Break-Even Analysis Summary Questions Problems
