Как да тестваме твърдостта на безпроблемните тръби от неръждаема стомана?
Твърдостта на безпроблемните тръби от неръждаема стомана също е много важен индикатор в конструкцията . Също така трябва да изберем квалифицирани продукти . За производството на безпроблемни тръби от неръждаема стомана, ние също трябва да свършим добра работа по тестване .} Нека говорим за това как да тестваме добрата работа на тестване
Mechanical property test methods are mainly divided into two categories, one is tensile test and the other is hardness test. The tensile test is to make a nickel-based welded pipe into a specimen, pull the specimen to break on a tensile testing machine, and then measure one or several mechanical properties, usually only tensile strength, yield strength, elongation after fracture and cross-sectional shrinkage. Tensile test is the basic mechanical property test method for metal materials. Metal materials, as long as there are requirements for mechanical properties, have tensile tests specified. Especially for those materials whose shapes are not convenient for hardness testing, tensile tests become a means of mechanical property testing.
The hardness test is to slowly press a hard tensile force into the surface of the specimen under specified conditions, and then detect the depth or size of the imprint to determine the hardness of the material. The hardness test is a simple, fast and easy-to-implement method in the mechanical property test of materials.
