High strength and heavy wall thickness steel pipes for building structures
In recent years higher tensile strength and heavier section of steel pipes have been required for building structures. JFE Steel has developed a series of steel pipes from 550 to 780 MPa tensile strength class (from 385 to 630 MPa yield strength class) with wall thicknesses of 40 to 100 mm by applying high performance steel plates. Mechanical properties of the pipes, particularly yield strength (YS) and yield ratio (YR), are focused in order to achieve high performance for the building frames. Both low YR and high YR (high YS) types of pipes, which are required according to various design requests, can be produced through controlling the mechanical properties of applied plates and the manufacturing processes of the pipes. As a result, it is considered possible to supply steel pipes which respond to more diverse design requirements than in the past.
