Features of Stainless Steel PipePublish:prwiremesh | Time: Monday, October 24, 2011
Brinell hardness is refer to the measure of indentation of a steel ball when a force is applied under specified pressure, typically 3,000 kilograms. After the test, measurement is taken and the metal is given a Brinell hardness number.Yield strength is also measured in megapascals (MPa). It refers to the measure of force the pipe can handle and still return to its original shape once the force is released. The yield strength of 316 stainless steel is 205 MPa, that of 420 is 1480 MPa and 430, also 205 MPa.
Elongation percent is refer to the percentage increase in the length of the stainless steel pipe during a tensile test. Two punch marks are made, the distance between them is measured, the test is administered and then the distance is measured again.
Tensile strength is the longitudinal stress or maximum force, the pipe can handle before tearing. It is measured in megapascals (MPa). 316 stainless steel pipe has a minimum tensile strength of 515 MPa, 420's tensile strength is 1,720 MPa and 430's is 450 MPa.
