Abstract
Influence of boron in a wide content range (0.0004–2.0%) and its joint effect with other alloying elements (Ti, Ce, Nb, Si, Mo, W, Al, N) on the structure and properties of austenitic stainless steels was analyzed. Due to segregation of boron along the grain boundaries and formation of various carbides, it is capable of increasing the strength and ductility, creep resistance and performance properties at high temperatures (> 600 °C). At the same time, a small boron content (≤ 0.004%), for example, in grade 304 stainless steel (Russian analogue—steel 08Kh18N10), leads to an improved corrosion resistance. However, with an increase in boron content (up to 2%), the positive effect disappears and steel becomes more susceptible to corrosion, while becoming stronger and inhibiting cracks formation during deformation due to grain refinement.
