Product Details


24 inch MS Seamless Piping Brinell hardness (HB)The steel ball or hard alloy ball with a certain diameter is pressed into the sample surface with the specified test force (F). After the specified retention time, the test force is removed and the indentation diameter (L) of the sample surface is measured.

24 Seamless Pipe

24 inch MS Seamless Piping Strength the ability of a metal to resist plastic deformation and fracture under external forcesThe ratio of the maximum load to the original cross-sectional area of the sample before the drawing is called Pb b= -- Fo in the formula Pb -- the maximum load (N) Fo before the drawing of the sample -- the original cross-sectional area of the sample (mm).The bending strength of the mechanical properties of seamless steel tubes


The 24 inch MS Seamless Piping measurement of brinell hardness is more accurate and reliable, but generally HBS is only applicable to 450N/mm2 (MPa) below the metal material, for the harder steel or thinner plate is not applicable.In the steel pipe standard, brinell hardness is the most widely used, often with indentation diameter d to express the hardness of the material, both intuitive, and convenient.For example, 120hbs10/1000130: indicates that the brinell hardness value measured for 30 seconds is 120N/ mm2 (MPa) under the action of 1000Kgf (9.807kn) test force with a diameter of 10mm steel ball.


Brinell hardness (HB)


The 24 inch MS Seamless Piping steel ball or hard alloy ball with a certain diameter is pressed into the sample surface with the specified test force (F). After the specified retention time, the test force is removed and the indentation diameter (L) of the sample surface is measured.Brinell hardness is the quotient of the test force divided by the surface area of the indentation sphere.The unit is N/mm2(MPa).The calculation formula is as follows:Where: F-- test force pressed into the surface of metal sample, N;D-- diameter of steel ball for test, mm;D -- average diameter of indentation, mm.
