Mechanical Properties Terms for Seamless Pipe

Index analysis of mechanical properties of seamless pipes (smls pipe):

1. The performance index analysis of seamless pipe--plasticity.

Plasticity refers to the ability of metal materials to produce plastic deformation without being damaged under load.

2. Analysis of performance index of seamless pipe--hardness.  

Hardness is a measure of the hardness of metal materials. At present, the commonly used method for measuring hardness in production is the indentation hardness method, which uses a certain geometric indenter to press into the surface of the metal material to be tested under a certain load, and the hardness value is determined according to the degree of indentation. Commonly used methods are Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV) and other methods.

3. The performance index analysis of seamless pipe--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 are working under cyclic loads, under which conditions the parts will fatigue.

4. Seamless performance index analysis--impact toughness.  

The load acting on the machine at a very large speed is called impact load, and the ability of metal to resist damage under impact load is called impact toughness.

5. Analysis of the performance index of seamless pipes--strength.  

Strength refers to the ability of metal materials to resist damage (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 connection between various strengths, and tensile strength is generally used as the basic strength indicator in use.
