What kind of welding rod does Q345 steel use?-

The hardness of the oil after the cold is at most 200HB or so,because he is low alloy,carbon content of about 0.16,so the basic quenching has little effect.Speaking of the impact area and the hardness after welding,the carbon content of Q345 is greater than 0.45%,so the welding process is strict,and the welding of Q345 steel in the Standard Specication for Anchor Bolts,Steel,36,55,and be heat treated by quenching in a liquid medium from above the transformation temperature and then tempering by reheat-ing to a temperature not less than 800 Quenching of Q345#176;F (425 Quenching of Q345#176;C) for Grade 55 and 1100 Quenching of Q345#176;F (593 Quenching of Q345#176;C) for Grade 105.6.4 Bending 6.4.1 When required,hooks,shall be made by cold bendingSome results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextSteel pipe knowledge---heat treatment processQuenching and low temperature tempering after nitriding.Example 1 Heat treatment scheme for several common steels Q345 The steel is steel for construction,bridges,etc.,and the yield strength is about 345 MPa.It is generally normalized and the carbon content is about 0.12-0.2%.

Q345 steel property and specification are equivalent to

Q345 steel is one kind of Chinese standardized low alloy,medium tensile strength steel made with a hot-rolling process,used for a number of manufacturing purposes.To some extent,the Q345 possesses the same property and composition of ASME A572,namely the Q345 is equivalent to A572.Q235 vs.Q345 Steel Plate (How to Distinguish) MachineMfgIf using the quenching method,a dense oxide layer will be formed on the surface and present the black color.When the general strength design is presented,Q345 is used because Q345 is not only strengthened than Q235 but also save 15% to 20% steel compared to Q235 steel.Q195,Q215,Q235,Q255 and Q275 in the material What is Grade Q345,Q390 steel,mechanical properties,weldability,hot and cold processing performance and corrosion resistance are good,C,D,E grade steel has good low temperature toughness.Mainly used for ships,boilers,pressure vessels,oil tanks,bridges,power station equipment,material handling equipment and other welded structure of high load.
