THIS DEPARTMENT CONTAINS ALL OF THE 18-8/304 STAINLESS STEEL FASTENERS. CLICK ON THE INDIVIDUAL FASTENER DEPARTMENTS FOR ADDITIONAL PRODUCT INFORMATION, SIZES AND PRICING. THIS IS A 300 SERIES OF STAINLESS STEEL HAVING APPROXIMATELY (Not Exactly) 18% CHROMIUM AND 8% NICKEL. THE TERM "18-8" IS USED INTERCHANGEABLY TO CHARACTERIZE FASTENERS MADE OF 302, 302HQ, 303, 304, AND 305 AND OTHER VARIABLES OF THESE GRADES WITH CLOSE CHEMICAL COMPOSITIION. THERE IS LITTLE OVERALL DIFFERENCE IN CORROSION RESISTANCE AMONG THE 18-8 TYPES, BUT SLIGHT DIFFERENCES IN CHEMICAL COMPOSITION DO MAKE CERTAIN GRADES MORE RESISTANT THAN OTHERS AGAINST PARTICULAR CHEMICALS OR ATMOSPHERES. 18-8 HAS SUPERIOR CORROSION RESISTANCE, IS GENERALLY NON-MAGNETIC, AND IS HARDENABLE BY COLD WORKING.
