The Seamless Steel Pipe Supplier shares with you!The performance of seamless steel pipes can be divided into two categories:
Performance: including mechanical properties, physical properties, chemical properties
Process performance: including casting performance, pressure processing performance, welding performance, cutting performance, heat treatment performance.
Seamless Steel Pipe
Simply put, the mechanical properties of seamless steel pipes are the ability of seamless steel pipes to resist external forces. The external force acting on the metal material. According to the nature of the load, it can be divided into static load, impact load and alternating load. Commonly used mechanical performance indicators are: strength, plasticity, hardness, impact toughness, fatigue strength, etc.
The strength of Seamless Steel Pipe refers to the ability of metal materials to resist deformation and 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, bending strength, and shear strength. The strength of steel pipes can generally be measured by metal tensile tests
The so-called plasticity refers to the ability of seamless steel pipes to produce permanent deformation without damage under static load. The plasticity index of metal is also measured by tensile test. Two indicators that mark the quality of metal plasticity are elongation and reduction of area.
Hardness is a measure of the hardness of seamless steel pipe. Usually refers to the ability of seamless steel pipe to resist harder objects pressed into its surface, and it can also be said to be the ability of seamless steel pipe material to resist deformation. Hardness is the property of a solid, which is manifested in different measurement methods and measurement conditions. It is also manifested in the ability of a solid to resist elastic deformation, plastic deformation or cracking, or resistance to two or three of them simultaneously ability.
The impact test is very sensitive to the defects of seamless steel pipes. Impact test is a traditional conventional mechanical test method. Because the sample is easy to process, the test time is short, and it is easy to distinguish whether the selection of materials and heat treatment process is reasonable, it has been widely adopted by the engineering community.
