ASTM A516 Grade 70 / ASME SA516 q345r composition
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.
It is a steel with less than 0.2 percent of its composition made up of carbon, less than 0.55 percent of its composition made of silicon and several impurities (mostly sulfur, chromium and nickel). This particular grade of steel is a 'general purpose' manufacturing steel in construction equipment field, such as Q345B is basic mateiral of making excavator bucket and Excavator long reach booms
Phosphorus, sulfur content slightly below the low alloy high strength steel Q345 (16Mn) steel, with the exception of tensile strength, elongation than Q345 (16Mn) steel increased, but also require the toughness. It is currently the most widely used, and the largest amount of special steel for pressure vessels.
Q345 steel specification and equivalent standard. Q345 is low alloy structural steel with good mechanical properties, low temperature performance, plasticity and good weldability, it is mostly used in low pressure vessel, oil tank, vehicles, cranes, mining machinery, power stations, mechanical parts, building structure, general metal parts,q345r composition

Q345R material shows good performance in structural purposes, so it is widely used as welding structural part in manufacturing of ships, railway and vehicles, bridges, boiler, pressure vessel container, steel oil tanks, etc. The minimum yield strength of Q345R material is 345 Mpa for thin thickness and tensile strength above 510 Mpa.
The ASTM equivalent of Q345B is A572 gr.50. This is a steel plate that is used in the construction of large structures like bridges.
At 30% rolled reduction rate, the average grain sizes of Q345R and NM500 are 20.3 and 25.3 m, respectively. The grains of both NM500 and Q345R became lower-sized and denser as the rolling rate was reduced. Due to the recrystallization degree increasing along with the rolling reduction rate increasing, the grains were constantly refined.
