hardness testing ways for high pressure boiler tubes

High pressure boiler tube hardness testing should take into consider its mechanical properties, which is related to stainless steel as raw material for the deformation like punching, cutting processing performance and quality.



Therefore, all of high pressure boiler pipes need to conduct mechanical testing. Mechanical performance testing way is mainly divided into tensile testing and hardness testing.

Take high pressure boiler tube sample, high pressure boiler tube tends to sample to the fracture on tensile testing machine. Mechanical properties and determination of one or more, usually determines tensile strength, yield strength, break elongation and reduction of area. Tensile test is the most basic mechanical properties of metallic materials testing methods. Almost all of the metal material, as long as the requirements of the mechanical properties of the high pressure boiler pipes, the provisions of the tensile test. In particular, those appearance and high pressure boiler tubes is not good for the material of hardness test, tensile test become the only ways of mechanical properties testing.
Applications: for high, middle, low pressure boiler and pressure purpose!
