Alloy element and the interaction of iron and A516 Gr.70 boiler and pressure vessel steel plate is that after joining in steel alloy elements, mainly exist in three forms in the steel for example with iron to form solid solution. With carbon to form carbide. In the high alloy steel may also form intermetallic compound.
1. Dissolved in iron
Almost all of the alloying elements (except Pb) can dissolve in iron, alloy ferritic of A516 Gr.70 boiler and pressure vessel steel plate or austenitic alloy formation, according to the alpha Fe or gamma - the role of Fe, alloy elements can be divided into expanding austenitic phase area and reducing austenitic phase two kinds big.
Expand in gamma phase elements - also called austenite stabilization elements, mainly is the Mn, Ni, Co, C, N and Cu etc., they make the A3 points (gamma - Fe alpha Fe shift point), A4 point (gamma - the transition of the Fe) rise, thereby expanding the presence of gamma phase range of Ni, Mn, etc to join after a certain amount, can make the gamma phase area expanded to below room temperature, the alpha phase disappeared, known as the fully expanded gamma phase area element. Other elements (such as C, N, Cu, etc.), while expanding gamma phase, but cannot expand to room temperature, so called part in expanding gamma phase element.
Narrow gamma phase elements - also known as ferritic stabilizing element, Cr, Mo, W, V, Ti, Al, Si, B, Nb, Zr, etc. They make A3 point rise, A4 point (except the chromium, chromium content of less than 7%, the A3 point. Rapidly rising more than 7%, A3 point), thus narrow the scope of the gamma phase zone exists, extend ferrite stable area. According to its role in different can be divided into completely closed gamma phase elements (such as Cr, Mo, W, V, Ti, Al, Si, etc.) and in part to reduce the gamma phase elements (such as B, Nb, Zr, etc.)
