A36 steel plate contains different amounts of other materials such as carbon, nickel, manganese, tungsten and molybdenum. Different components in sa573 grade 70 structural quality carbon steel A36 steel plate will produce different properties. The modulus of elasticity (i.e. hardness measurement) of all A36 plates is 29 million psi.
Bridge steel plates are thick steel plates made of carbon steel and low-alloy steel for bridge construction. The main applications of bridge steel plates are to build railway bridges, highway bridges, and sea-crossing bridges. The bridge steel plates are required to have high strength, durability and bear the load and impact of rolling stock. Bridge steel plates have good water resistance, low thermal conductivity, flat and lubricated surface. The main grades of bridge steel plates are A709 grade 50, A588 grade B, sa573 grade 70 structural quality carbon steel and so on.
The characteristic of niobium in sa573 grade 70 structural quality carbon steel etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.
