Under EN10083-2:2002 standard,C22R \/ 1.1149 Special Steel\u00a0is to point to to meet a certain strength and\u00a0formability levels of steel. Formability tensile test to break elongation said. Structural steel are used for\u00a0carrying such use, in these USES\u00a0the strength of steel<\/strong>\u00a0is an important design standards.<\/p>\n
