Carbon steel seamless pipes are extensively applied in the nuclear device, gas conveyance, petrochemical, shipbuilding and boiler industries, which with characteristics of excellent durability and corrosion resistance. Union Steel - seamless steel pipe factory will briefly introduce the mechanical properties terms of carbon steel seamless pipe in the following text.
1. Analysis of performance indicators of seamless pipes - plasticity.
Plasticity refers to the ability of metal materials to produce plastic deformation under load without damage.
2. Analysis of performance indicators of seamless pipes - hardness.
Hardness is a measure of the hardness of a metallic material. The method commonly used to measure hardness in production at present is the indentation hardness method, which uses an indenter with a certain geometric shape to press into the surface of the metal material to be tested under a certain load, and determines the hardness value according to the indentation hardness value. Degree of indentation. Commonly used methods include Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV).
3. Analysis of performance indicators of seamless pipes - fatigue.
The strength, plasticity, and hardness discussed above are all indicators of the mechanical properties of metals under static loads. In fact, many machine parts operate under cyclic loads, where the parts fatigue.
4. Analysis of seamless performance indicators - impact toughness.
A load acting on a machine at a high speed is called an impact load, and the ability of a metal to resist damage under an impact load is called impact toughness.
5. Analysis of performance indicators of seamless pipes - strength.
Strength refers to the ability of a metallic material to resist failure (excessive plastic deformation or fracture) under static load. Since the load acts in the form of tension, compression, bending, shearing, etc., the strength is also divided into tensile strength, compressive strength, flexural strength, and shear strength. There is often a certain relationship between various strengths, and tensile strength is generally used as the basic strength index in use.
