General Product Description
The Docol HR500Y550T HE steel is the next generation of hot-rolled high-strength low-alloy steels with improved local formabilityfor higher edge ductility and cut-edge quality.
Docol HR500Y550 HE have a new and closely controlled production method resulting in a veryfine microstructure in combination with a very clean steel, resulting in greatlyimproved local formability while still retaining a good global formability making it suitable for stamping most geometries and will excel in demanding forming where the cut edges maylimit the forming operation.
The improved cut edge quality achieved with this new way of producing Docol HR500Y550 HE with a steel less sensitive to tool-settings and –wear compared to conventional HSLA grades, make it especially suitable for fine blanking.
HR500Y550T HE will have a typical hole expansion of approx. 30 percentage points above the corresponding conventional HSLA grade. Also the bending performance is improved and a bend radius of 0xt can be guaranteed.
Docol HR500Y550T HE will excel when optimizing anyfine blanking, stamping or forming operation and will push the limit on how to utilize the benefits of steel.
Docol HR500Y550T HE can after agreement be adapted and delivered as dual certified with S500MC according to EN 10149-2.
Dimension Range
Docol HR500Y550T HE is available as Hot-rolled pickled and oiled coil, slit coils and cut to length sheets in thickness of 2.00*) - 7.00 mm and widths up to 1600 mm. Length up to 16 meters.
*)Some restrictioins may occur, and will be handled on request.
