PROCESS FOR PRODUCING A COMPOSITE FLAT PRODUCT, STAINLESS ARMOR AND ARMORED STORAGE TANK OBTAINED BY THIS PROCESS

Plating is carried out of a stainless steel sheet whose carbide redissolution temperature is lower than 1000 DEG C. onto an armor steel sheet and the plated sheet obtained is quenched so that the Brinell hardness of the armor steel is between 250 and 700 BH. The plating may be carried out by corolli...

Beschreibung
Zusammenfassung:	Plating is carried out of a stainless steel sheet whose carbide redissolution temperature is lower than 1000 DEG C. onto an armor steel sheet and the plated sheet obtained is quenched so that the Brinell hardness of the armor steel is between 250 and 700 BH. The plating may be carried out by corolling, explosion plating or explosion plating followed by rerolling. Tempering may be performed at a temperature between 200 DEG and 600 DEG C. on the plated and quenched sheet. The quenching is preferably carried out on an oil quenching machine under a press. The armors obtained comprise a stainless coating layer free from carbide precipitates at the grain boundaries. Storage tanks which resist projectiles and are employed for storing liquid corrosive products can be made from the stainless armors according to the invention.
