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 q345b vs q345
According to GB/T 1591 2008, Q345 material has 5 quality grades: Q345A, Q345B, Q345C, Q345D and Q345E. Q345 steel has good weldability, cold & hot workability and corrosion resistance. Widely used in bridges, ships, boilers, pressure vessels, petroleum storage tanks, lifting transport machinery and other high-load welded structural parts.
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.
When the general strength design is presented, Q345 is used because Q345 is not only strengthened than Q235 but also save 15% to 20% steel compared to Q235 steel. However, for stability control design, Q235 steel is better. The price difference is 3%- 8%. Regarding how to distinguish the steel plate from Q235 and Q345, therere several methods:
Q345B (China, GB ) - European (EU, EN) and wordwide Steel equivalent grades These comparison table is only intended as an indication of the closest khown equivalent grades. The source standarts should always be checked for the specific purpose for each material, in case of doubt Buy, sell, suppliers search product Q345B on-line
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..
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.
What is Q235 steel grade? - Quora Jun 25, 2016
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)
The difference between Q345 and Q235 . q345b vs q345 Q345A, Q345B, Q345C, Q345D, Q345E. This is a class distinction represents mainly the impact of temperature differs only!

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.
Q345 structural steel has good mechanical properties, low temperature performance, plasticity and good weld ability, Q345 steel is mostly used in low pressure vessel, oil tank, vehicles, cranes, mining machinery, power stations, mechanical parts, building structure, and general metal parts.
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
ss400 vs q345 plate steel is a building material composed of chemical components such as silicon, sulfur and phosphorus. ss400 vs q345 plate can be used F, b, z were expressed as boiling steel, semi-static steel, killed steel. Boiling steel is incompletely deoxidized steel with poor plasticity and toughness.
Q345B is black carbon steel. The specification of a Q345B steel sheet depends on what you want and ranges from 6 to 120mm thick, 1600 to 3200mm wide and 6000 to 12000mm long.
Q345B steel is a Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, and is used for a number of manufacturing purposes. 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 q345b vs q345
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
