Chemical composition of 10MoWVNb: Chemical composition of the grade (mass fraction) (%): C, Si, Mn, P ≤ S ≤ Cr, Mo, V, Others. For 10Mowvnb: 0.07–0.13, 0.50–0.80, 0.50–0.80, 0.03, 0.030, _, 0.60–0.90, 0.30–0.50; W: 0.50–0.90; Nb: 0.06–0.12. Mechanical properties of 10MoWVNb: Grade, tensile strength in MPa, yield strength in MPa, elongation (%): 10MoWVNb – 470–670, 295, 19. 10MoWVNb is used in chemical equipment pipelines operating at temperatures ranging from -40 to 400 degrees Celsius and under pressures of 10–32 MPa. For the chemical composition and mechanical properties of 10CrMo910, please visit http://www.tjtgggc.com/xhzy.asp?id=6. Characteristics of 10CrMo910: It is the most widely used alloy heat-resistant steel, with good permanent plasticity; creep begins in its third stage only when the elongation reaches 3%–5%. Widely used in various heating surface pipes in thermal power, nuclear power, and petrochemical industries ； Applications: Superheater tubes with a wall temperature below 580°C, as well as header and steam pipes with a wall temperature below 570°C.
