Under EN10084-1998 standard,Structural steel 16MnCrS5 means a specific level of strength and formability of steel. Tensile test can be formed after the interruption of the elongation said. Structural steel usually used for carrying purposes, the strength of steel in these applications is an important design criteria.Structural steel 16MnCrS5 can be broken down as follows: alloy steel carbon steel low alloy steel heat-resistant steel and so on.
