The difference between application of 20# steel and Q345 steel. 20# steel is mainly used for making parts, which can be heat treated; Q345 steel is mainly used for making engineering structural parts, which is usually not heat treated. Q345 steel does not emphasize the composition, but its yield strength must be above 345mpa. Because the composition astm a573 grade 50 is not fixed, Q345 steel is difficult to heat treatment (the temperature and time control of heat treatment are related to the composition, and different components use different processes).
We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product astm a573 grade 50 annual capacity is 200 thousand tons.
The related factors of astm a573 grade 50 steel plate cutting are mainly steel plate material, steel plate specific use and steel plate cutting requirements, so it can be said that there are many related factors. Different processing methods, such as finish machining and rough machining, choose different astm a573 grade 50 steel plate cutting methods. Wire cutting or plasma cutting is used for finishing and flame cutting is used for rough machining. Therefore, it can be concluded that the steel plate cutting methods selected under different processing methods are different.
