What are the characteristics of large diameter steel pipes?
1. Impact toughness: The load acting on the machine parts at a high speed is called impact load, and the ability of metal to resist damage under impact load is called impact toughness.
2. Strength: Strength refers to the resistance of metal materials to damage (excess plastic deformation or fracture) under static load. Since the load acts in the form of stretching, compression, bending, shearing, etc., the strength is also divided into tensile strength, compressive strength, bending strength, shear strength, etc. There is a corresponding relationship between various strengths. In use, the tensile strength is generally used as the basic strength indicator.
3. Plasticity: Plasticity refers to the ability of a metal material to undergo plastic deformation (long-term deformation) without breaking under load.
4. Fatigue: The strength, plasticity, and hardness discussed above are all indicators of the mechanical properties of metals under static load. In fact, many machine parts work under cyclic load, under which conditions the parts will fatigue.
5. Hardness: Hardness is an indicator to measure the degree of softness and hardness of metal materials.
