Method of making a composite drawn article

A method of making a composite drawn article comprised of at least a central stratum of plain-carbon steel and two exterior strata of stainless steel, said method comprising the steps of:

• forming an article which contains a central stratum of plain-carbon steel and two exterior strata of stainless steel, with interleaving strata between said exterior strata and said stratum of plain-carbon steel, said interleaving strata being of steel containing more than 0.50 and up to 4.5 weight percent silicon, and said interleaving strata having between them a thickness of less than 25 percent of that of the entire article;
• hot rolling said article at a temperature in excess of 1600 degrees F. so as to form a bond therebetween and thereby produce a composite;
• cold rolling said composite;
• annealing the cold-rolled composite at a temperature in excess of 1800 degrees F., said composite having a yield strength at 0.2 percent offset of under 50,000 pounds per square inch;
• and
• forming by deep drawing the annealed composite, thereby producing a composite deep drawn article.
