Q345D seamless pipe
Main characteristics of Q345D seamless pipe:
Q345D seamless pipe product application:
Ships, boilers, pressure vessels, oil storage tanks, bridges, power plant equipment, hoisting and transportation machinery and other welding structures with high loads
Q345D seamless pipe old standard control:
18nb contains NB killed steel, with properties similar to 14MnNb, mainly used for cranes, blowers, chemical machinery, etc
09mncupti atmospheric corrosion-resistant steel, with good low-temperature impact toughness, weldability, cold and hot processing performance, is mainly used for various machines in wet and rainy areas and corrosive atmosphere
12mnv working temperature is - 70 ℃ low temperature steel, mainly used for freezing machinery, structural parts working at low temperature
The performance of 14MnNb steel is similar to that of 18nb steel, which is mainly used for vessels and other structural parts with working temperature of - 20-450 ℃
16Mn has good comprehensive mechanical properties, low temperature performance, cold stamping performance, welding performance and machinability, and is mainly used in mining, transportation, chemical and other machinery
16mnre is similar to 16Mn steel in performance, and its impact toughness and cold bending performance are better than 16Mn steel. Its application is the same as 16Mn steel
