how to measure the hardness of steel pipe

When it comes to the steel pipe, we know little knowledge on how to measure the hardness of steel pipe whatever the types of pipe are. The hardness is an important factor when customers are willing to purchasing seamless tube. Today, our technical team will teach you some methods how to measure the hardness of steel pipe.

The hardness testing is based on the mechanical properties including the feedstock on performance and quality for the steel pipe deformed by stamping or cutting. There are two ways for the mechanical properties test of steel pipe: tensile test and durometer hardness test.

How to Measure Hardness of Steel Pipe


Tensile test is generally measured the tensile strength and elongation and necking rate of the seamless pipes. The steel pipe sample is pulled to fracture on tensile testing machine to check one or several mechanical properties. Metal raw material is determined the basic mechanical properties. As long as the mechanical properties required, the metal material has predetermined the tensile test of the steel tube. The tensile test is very inconvenient for the hardness measurement of the work piece, but it is only way to test mechanical properties.

The durometer hardness test requires pushing the pressure head of hard conditions into the workpiece surface slowly to measure indentation depth and size that is the hardness of material subsequently. The hardness test is not only the most convenient means in the detection of mechanical properties but also non-destructive testing. Due to inconvenient tensile test, the hardness conversion to strength is very easy. So you only test the hardness of the material of the steel pipe.
