Q345 steel property and specification are equivalent to

The major benefit of Q345 steel is its mild temper, easy to form and weld. 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. Q460 Steel Chemical Composition, Specifications Q460 Steel Introduction. Q460 steel is a Chinese steel grade of Low Alloy High Strength Structural Steel, Yield Strength is 460 MPa, data is tested with 16mm diameter steel bars or steel plates, tensile strength is 550-720 Mpa, test with steel bar Quenching of Q345#216;40mm.For Q460 steel equivalent, chemical composition and mechanical properties, please see the tables below.

Steel Wind Turbine Tower Material Reviews - CNBM Wind

The manufacture technology of low alloy high strength steel is mature in China. Therefore, Q345 grade is not the only steel grade option for wind turbine tower manufacture. Except Q345 steel , There are also other low alloy hight strength steel grades that are suitable for wind turbine tower manufacture. Structural Ms Carbon Steel Plate A36 Q235 Q345 S275jrStructural Ms Carbon Steel Plate A36 Q235 Q345 S275jr Product Introduction 65# is medium-high carbon spring steel. The steel has high strength, hardness and elasticity after heat treatment or cold hardening, low cold deformation plasticity, poor welding properties, generally using oil quenching, large section parts using water quenching oil cold or

What kind of welding rod does Q345 steel use?-

The hardness of Q345 is below HB180. 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 cooling process, the heat affected zone quenching pipe, quenching pipe Suppliers and A wide variety of quenching pipe options are available to you, such as hot rolled, erw, and cold drawn. You can also choose from 10#-45#, a53-a369, and q195-q345 quenching pipe, as well as from 10#, a53(a,b), and q235 quenching pipe, and whether quenching pipe is structure pipe, or hydraulic pipe.
