C22E / 1.1151 Special Steel
Under EN10083-2:2002 standard,C22E / 1.1151 Special Steel is to point to to meet a certain strength and formability levels of steel. Formability tensile test to break elongation said. Structural steel are used for carrying such use, in these USES the strength of steel is an important design standards.
C22E / 1.1151 Special Steel can be divided into: alloy steel carbon structural steel low alloy steel heat resistant steel, etc.
