USE OF NIOBIUM HIGH STRENGTH STEELS WITH 450 MPA YIELD STRENGTH FOR CONSTRUCTION
This paper presents an actual case of a new industrial building at CBMM”s plant in Araxá,Brazil as an example of lean design using microalloyed steels.The structure consists mostly of microalloyed ASTM A572 steel grades 65 and 50 instead of the conventional carbon manganese ASTM A36 steel.The application of grade 65 with more than 450 MPa of yield strength is an innovative solution for this type of construction in South America.A complete welding evaluation performed on the low carbon,niobium microalloyed grade 65 steel showed the welding properties and benefits.Niobium”s effect of increasing strength and toughness simultaneously resulted in relevant savings in total steel consumption for the project.The paper also quantifies the expected savings in costs,energy and carbon dioxide emissions.
