Q is the first letter of Chinese Pinyin: qu fu dian, which means Yield Point, 345 is the minimum value of yield strength 345 MPa for steel thickness 16mm. Datasheet and Specification
A yield strength or yield point is the material property defined as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed, Yield strength of Q345B is 345 MegaPascals.
The tensile strength of Q345B steel is rated at 470 to 630 MegaPascals (where mega is million) and a yield strength (where the material starts to thin and pull like taffy) at 345 MegaPascals. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20-21 percent of its initial length.
Before the yield point, the material will be elastic and return to its original shape when the applied stress is removed. The yield strength of Q345B is 345 mpa. Like most grades of steel, it is elongated before pulling apart, usually 20-21% of its initial length.
the yield strength of Q345B is 345MPa for thicknesses <= 16 mm. 325MPa for 16 mm < thickness <= 35 mm. 295MPa for 35 mm < thickness <= 50 mm. 275MPa for 50 mm < thickness <= 100 mm.
Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed. Yield strength of Q345B is 345 Mega Pascals. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20-21 percent of its initial length.

Hello everybody: The Technical Specifications for metal works (gates, trash racks, etc.) of a hydro project indicate, particularly, for the gates to use steel ASTM A572 Gr 50 or its equivalent S355JR according to EN 10025. The Contractor is trying to change that material to steel Q345B (chinese material and code).
This page provides Q345 datasheet download, these include Q345 mechanical properties, chemical element Q345, technical specifications of Q345 steel material properties.
the material difference of Q345A, Q345B, Q345C, Q345D and Q345E Q345 is a kind of steel material. It is a low alloy steel (C<0.2%), widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.. Q represents the yield of this kind of material, the 345 refers to the yield value of this material, in the 345 or so.
Q is representative of the material yield, 345 refers to the material yield value, minimum to achieve 345 mpa. Q345A, Q345B, Q345C Q345D, Q345E mild steel pipe. And this is the distinction between grade, represents the main impact of temperature is different,
q345b,q345b plate,q345b steel Steel grade Q345B is the most common used as high strength low alloy structural steel in industry area.Xinsteel can offer steel coils,steel plates,angles,channels for Q345B materials.The equivalent steel grade with Q345B are EN 10025-2 S355JR,ASTM A572/A572 A572 Grade 50 and DIN 17100 St52-3.
1) Application Potential: The steel plate of Q345 is applied to manufacture factory building, civil building and all kinds of engineering machinery in mine industry and various of civil construction, such as drilling rig, electric shovel, powered wheel tipper, mining vehicles, excavators, loaders, bulldozers, industrial blowers, various types of cranes, mining machinery and equipment,such as , q345b yield
And will increase the thickness of the material and its yield value decreases. Q345A, Q345B, Q345C, Q345D, Q345E. This is a class distinction represents mainly the impact of temperature differs only!

Answer Wiki. 1 Answer. , Health and Pharmaceutical Expert. 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.
Even though chemical composition is a dominant factor in determining the mechanical properties of steel, it is also very important to understand the minimum standards for the mechanical properties or performance characteristics, such as yield strength and tensile strength, which are described in more detail below.
