Disclosed are alloying elements and microstructures suited for realizing a marked increase in strength of low-carbon or ultra-low-carbon steel plate using a high-density energy source such as a laser. Steel blanks satisfying both high formability and high strength requirements are provided which show sufficient press formability and yet can be markedly increased in strength by laser treatment or which have been markedly increased in strength by laser treatment in areas not to be subjected to severe forming.

Process of Producing high-formability steel plate with a great potential

The object of the present invention is to provide an aluminum plate for fabrication which has an excellent formability, easy degrease after fabrication, coating properties, and less tendency of flawing, in which the aluminum plate for fabrication which is plated, and coated with a lubricant containing (A) a fatty acid ester of polyol, (B) an alkaline or alkaline metal salt of sulfonate, and (C) a controlling agent, and having saponification value of 20 or more.

Aluminum plate excellent in formability
