43、 8/7/13 11:24 AMAISC DESIGN GUIDE 27/ STRUCTURAL STAINLESS STEEL / 1Chapter 1 Introductionperformance can be further enhanced by higher levels of chromium and additions of molybdenum and nitrogen.Ferritic stainless steelsThe chromium content of the most popular ferritic stainless steels is between 1

44、0.5% and 18%. Ferritic stainless steels contain either no or very small nickel additions and their body-centered atomic structure is the same as that of struc-tural carbon steels. They are generally less ductile, less form-able and less weldable than austenitic stainless steels. They can be strength

45、ened by cold working, but to a more limited degree than the austenitic stainless steels. Like the austenit-ics, they cannot be strengthened by heat treatment and can be used in a broad range of corrosive environments. They have good resistance to stress corrosion cracking and their corrosion perform

46、ance can be further enhanced by additions of molybdenum.Duplex stainless steelsDuplex stainless steels have a mixed microstructure of aus-tenite and ferrite, and so are sometimes called austenitic-ferritic steels. They typically contain 20 to 26% chromium, 1 to 8% nickel, 0.05 to 5% molybdenum, and

47、0.05 to 0.3% nitrogen. They provide higher strength levels than austenitic steels and are suitable for a broad range of corrosive environ-ments. Although duplex stainless steels have good ductility, their higher strength results in more restricted formability compared to the austenitics. They can al

48、so be strengthened by cold working, but not by heat treatment. They have good weldability and good resistance to stress corrosion cracking.Martensitic stainless steelsMartensitic stainless steels have a similar body-centered cubic structure as ferritic stainless steel and structural car-bon steels,

49、but due to their higher carbon content, they can be strengthened by heat treatment. Martensitic stainless steels are generally used in a hardened and tempered condition, which gives them high strength and provides moderate cor-rosion resistance. They are used for applications that take advantage of their wear and abrasion resistance and hard-ness, like cutlery, surgical instruments, industrial knives, wear plates and turbine blades. They are less ductile and more notch sensitive than the ferritic, austenitic and duplex stainless steels. Although most martensit
