Abstract

PURPOSE: To obtain a steel plate capable of being well coated with Al by passing through an NOF type Al hot-dipping apparatus as cooled, by specifying C, Si, Mn, Cr, Al and carbon equiv. in steel.
CONSTITUTION: This steel plate consists of ≤0.15% C, ≤2.2% Si, 0.1W2.4% Mn, ≤2.0% Cr, 0.002W0.080% Al and the balance Fe with inevitable impurities and has ≤0.44% C equiv. according to the equation or contains ≤)0.30% Ti and/or Nb furthermore. More C is preferable in strength, yet C is restricted with respect to the spot weldability. More Si is preferable in strength, yet Si is restricted with respect to the suitability to hot dipping. Mn has the same action as Si and acts in the formation of a composite structure in the steel, yet it is restricted with respect to the hardening of the weld zone. More Cr is preferable in strength, yet Cr is restricted with respect to the upper limit of the C equiv. Al enhances the deoxidation and the addition yields of Si, Mn and Cr, yet excess Al deteriorates the ductility. The C equiv. is restricted with respect to the weldability.
