Attentions in machining Q345NQR2 hot rolled bridge steel chemistry

Q345D seamless pipe has good comprehensive mechanical properties, low temperature impact toughness, cold stamping and cutting processability, weldability. In Q345D seamless pipe, Q is the abbreviation of yield strength, 345 is the yield strength value, that is, the yield strength of Q345D seamless pipe is 345 MPa, and D is the impact temperature, which is minus 20℃. Q345NQR2 hot rolled bridge steel chemistry, Q345D seamless pipe is widely used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, storage tanks, heavy machinery and equipment, mining machinery, power stations, plant structures, low-temperature pressure vessels, textile machinery parts, etc.

Medium and thick steel plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on. However, each project has different requirements for plate size. How to cut Q345NQR2 hot rolled bridge steel chemistry, medium and thick steel plates? There are many ways, for example, flame cutting, laser cutting, wire cutting, plasma cutting, ultra-high pressure water cutting and so on.
