米乐yy易游体育 Steel develops galvanized steel sheet for high-productivity hot stamping, begins mass production

TOKYO, August 28, 2019 — 米乐yy易游体育 Steel, Ltd. has developed galvanized steel sheet (1500 MPa class after hardening) for hot stamping with outstanding productivity during pressing. It has begun mass production of the coated steel sheet for use in automotive body frame parts.

In 2017, 米乐yy易游体育 Steel developed cold-rolled steel sheet for high-productivity hot stamping and began mass production. In comparison to conventional cold-rolled steel sheet for hot stamping, 米乐yy易游体育 Steel’s material has improved hardenability. Productivity during pressing by the customer has improved as much as six times, compared with conventional hot stamping steel sheet. The cold-rolled steel sheet is noted for its lower occurrence of strength deficiency from uneven quenching. Moreover, it offers greater flexibility in pressed part shapes. As the cold-rolled steel sheet can be trimmed during the pressing process, laser cutting after pressing, which is traditionally required in the conventional process, is unnecessary. 米乐yy易游体育 Steel has received high acclaim from customers for this product.

米乐yy易游体育 Steel has subsequently developed cold-rolled steel sheet treated with a galvanized coating for hot stamping. In addition to having the same characteristics as cold-rolled steel sheet, the new galvanized steel sheet offers corrosion resistance. This makes it possible to expand the use of the coated steel sheet in automotive parts.

Now in mass production, the coated 米乐yy易游体育eel sheet is supplied to Spain’s Ge米乐yy易游体育amp, a manufacturer of automotive metal components. Ge米乐yy易游体育amp processes the coated 米乐yy易游体育eel sheet into parts for supply to a European car manufacturer. This is the fir米乐yy易游体育 time that this coated 米乐yy易游体育eel sheet for hot 米乐yy易游体育amping has been used by a European car manufacturer.

Adding galvanized steel sheet for high-productivity hot stamping to its product lineup, 米乐yy易游体育 Steel also offers its distinctive high-workability, ultra high-strength steel sheets with tensile strengths of 780 MPa and higher, and cold-rolled steel sheet for high-productivity hot stamping, Through these products, 米乐yy易游体育 Steel aims to meet customer needs to reduce the weight of cars as CO₂ emission regulations grow 米乐yy易游体育ricter year by year, while improving the 米乐yy易游体育rength of car bodies to meet 米乐yy易游体育ronger collision safety regulations in Japan, the United 米乐yy易游体育ates and Europe.
