General Info About C1020 or 1020 Steel

C1020 is also known as 1020 steel plate and is used in the turned and polished or cold drawn condition. It has a low carbon content and is therefore resistant to induction or flame hardening. It also won’t respond to nitriding due to its lack of alloying elements.

More Details About C1020 or 1020 Steel

  • Advantages/Disadvantages

    This grade has improved formability, good weldability, high strength, and high ductility. But because of its low carbon content, it is resistant to induction and flame hardening.

  • Industries

    Some common industries are the automotive, heavy truck, and agricultural equipment industries.

  • Applications

    It is used in case hardened condition and often for simple structural applications. Typical applications for C1020 are axles, machinery parts, shafts, ratchets, worm gears, and spindles.

  • Machining

    This grade steel plate has a controlled carbon range and therefore high machinability capabilities. Especially in the cold drawn and turned and polished condition, 1020 has high machinability.

  • Welding

    The most common welding processes are used for this grade. Better weldability is caused by using cold drawn or the turned and polished condition. It is not recommended to do the welding process in heat treated or carburized condition.

  • Heat Treatment

    C1020 steel plate is heat treatable. The order of the heat treating process include, annealing, carburizing, core refining, case hardening, tempering, normalizing and finished with  stress relieving.

Questions about 1020 steel

  • What are the properties of 1020 steel?

    1020 steel has a tensile strength of 420 MPa and a yield strength of 350 MPa. 1020’s modulus of elasticity is 205 GPa and the shear modulus is 80GPa. It has high machinability, good weldability and high ductility. 1020’s Poison’s ratio is 0.29 and the elongation at break (in 50mm) is 15%. C1020 has low hardenability properties and is a low tensile carbon steel with Brinell hardness of 121.

  • What is a steel 1020 equivalent?

    In ASTM standards, the equivalent steel is referred to as A108, A29 type steel.

  • What is 1020 steel density?

    Density: 7.87g/cc – 0.283lb/in3
