With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Q345 steel specification: Q345 steel belongs to 16Mn steel grade, usually it is produced in hot rolled state, hot rolled steel plate, hot rolled steel coil/sheet, it has comprehensive mechanical and welding property, as it shows good performance in structural purposes, it is widely used as welding structural part in manufacturing of ship buy q345 vs s355
Elongation for Q345 is at the bottom end of the specification which is 0.22% while the local manufactured tube is an average is 0.37%. Lastly but importantly the minimum yield of Q345 is 345MPa which is not the same as the minimum yield of grade S355 which is 355MPa. (For thicknesses less than 16mm)
EN 10025 S355 Steel. S355 steel is a European standard structural steel grade, according to EN 10025-2: 2004, material S355 is divided into 4 main quality grades: S355JR (1.0045), S355J0 (1.0553), S355J2 (1.0577) and; S355K2 (1.0596). The properties of structural steel S355 is better than steel S235 and S275 in yield strength and tensile strength.
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 strength is 470-630 Mpa, and yield strength is 345 MPa. According to GB/T 1591 2008, Q345 material has 5 quality grades: Q345A, Q345B, Q345C, Q345D and Q345E.

Q345 steel is an alternative to the old steel grades of 12MnV, 14MnNb, 18Nb, 16MnRE, 16Mn, etc., and it is not just a substitute for 16Mn steel. In terms of chemical composition, 16Mn and Q345 are also different.
S355 is a non-alloy European standard (EN 10025-2) structural steel, most commonly used after S235 where more strength is needed. It got great weldability and machinability, let us see more mechanical details of this steel.
A36 steel plate is similar to Q235B steel plate, it is one Q235b equivalent steel standard, another one is SS400. While the difference between A36 and Q235B is as follows:
Structural Steel Plate, Beams, Columns, Channels, Angles - S275, S355. S275 a structural grade steel with a minimum yield strength of 275 N/mm S355 a structural grade steel with a minimum yield strength of 355 N/mm. S275. S275 suitable for numerous general engineering and structural applications
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.
