Product specification and composition: Steel is an alloy of mainly iron and carbon, with small amounts of elements used as alloying elements. These elements improve the chemical and physical properties of steel such as strength, durability and corrosion resistance. The alloying elements of steel are closely linked to its chemical matrix. The steel used in steel structures meets the quality criteria for steel according to EN standards. Welding consumables and coatings are the other raw materials used in the manufacture of steel structures.Measures are done to a level of 0,02 µg/g (0,00000002%). Concentrations below this degree of measuring accuracy cannot be determined.Example of the composition of a structural hollow section made of SSAB double grade (S355J2H, S420MH) steel.MaterialName if ingredientMaximum part content, % (w/w)CAS numberRisk and hazard phrases and other data on the ingredientS420MH/S355J2 steel
