scope:
This grouping of alloy steels, because of the combination of high strength and high toughness, is important to many engineering applications and thus is included in this volume of the Welding Handbook as a separate chapter. This chapter covers the weldability of certain selected steel alloys with compositions that include total alloy additions of more than about 10%. This chapter does not include stainless steels, chromium- molybdenum steels, 9%-nickel steels, such as ASTM A 353 and A 553, or tool steels.1, 2,3 Alloy additions are intended to improve the properties of steels. As a basic example, the tensile strength of plain carbon steel may be increased simply by raising the carbon content. However, this approach has several limitations. Principal limitations to alloy additions are that plain high-carbon steels have poor weldability and relatively shallow hardening during rapid cooling. Also, toughness and ductility are inadequate for many applications, and the range of mechanical properties usually is severely limited. Nevertheless, many high-strength carbon steels are used for structural applications in the quenched-and-tempere
