Q345 steel specification and equivalent standard Q235 carbon structural steel is made for metal construction that doesnt have high demand for steel strength, tie rod, connecting rod, hook, coupler,equivalent material q345a Q345 is low alloy structural steel with good mechanical properties, low temperature performance, equivalent material q345a
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 Mega Pascals.

There are number of different grades of Q345 Steel going from A to E.  They appear to be base on variations of AISI 1020 or 1018. China is controlling a number of elements that are not normally controlled in these steels in the USA. It would also come under the general heading of low alloy or Low Carbon Steel. Niel Leon
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.
Q345 Steel Properties and Introduction Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strengthequivalent material q345a Q215 Steel, Q215A, Q215B Chemical Composition, Properties & Equivalent
GB/T1591 Q345 includes five different steel grades as Q345A,Q345B,Q345C,Q345D and Q345E.These high tension steel grades owned the same mechincal properties,minimum yield strength at 345Mpa and tensile strength within 470-630Mpa.
According to the color of the steel plate, the Q235 and Q345 materials can be distinguished: the color of Q235 is blue, and the Q345 is red (this is only for the steel that just came into the market, and if the time is long then it also cannot be distinguished).
Q345 steel equivalent is standard Grade Q345 Imported Tube does not conform to grade S355 It has come to the attention of the ASTPM that Grade Q345, a standard in China, Grade Q345 it is not equivalent to S355 in terms of mechanical properties in Q345 Steel Equivalent - Alibaba
Q345 is a steel material. It is low-carbon steel (c <0.2%), good overall performance, good low temperature performance, the performance of cold . stamping, welding performance and good cutting. Widely used in bridges, vehicles, ships, construction, pressure. vessels.
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.
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).
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.
Boiler steel plate Q345R is the most used materials to build specified elevated boilers and pressure vessels.Q345R owned the minimum yield strength at 345 Mpa for thin thickness and tensile strength above 510 Mpa.The best equivalent steel grade with Q345R is A516 Grade 70 in specification ASTM A516/A516M.
