Desenvolvimento De Aços Microligados Com Alta Resistência Mecânica e Boa DUCTILIDADE1 (original) (raw)

Abstract

Abstracts The aim of this work was to identify, through laboratory hot rolling tests, the most adequate,alloys and process,parameters,that must,be used,for the production,of hot coils of HSLA steels with good ,ductility. The aimed ,value ,ranges ,for mechanical properties are: yield strength, 450~550 MPa; tensile strength, 550~650 MPa; maximum yield ratio, 0.85; and total elongation, 25%. The results got from the
