Under EN10084-1998 standard,Structural 16MnCr5 steel PLATE 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 16MnCr5 steel PLATE can be broken down as follows: alloy steel carbon steel.
