ASTM A572 steel plate is made of A572, a High-Strength Low-Alloy, Columbium-Vanadium Structural Steel. There are five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars. Grades 42 , 50 , and 55  are best for riveted, bolted, or welded structures. Datasheet for Steel Grades Structure Steel Q345This page is mainly introduced the Q345 Datasheet, including chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of Q345,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.

Distinguish Q345 and Q235 B method: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). The most distinguishable test is chemical analysis.

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 Q345B,Q345B PLATE,Q345B STEELSteel 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. Q355 Steel, Q355B Q355C Q355D Properties, Composition Q355 Steel (Q355B Q355C Q355D) Q355 steel is a Chinese low alloy high strength structural steel, which replaced Q345, the material density is 7.85 g/cm3.According to GB/T 1591 -2018, Q355 has 3 quality levels:Q355B, Q355C and Q355D.. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Strength, 355 is the minimum value of yield strength 355 MPa for steel
The typic steel plates of penstocks of hydropower stations in China are carbon steel of steel grade Q235 and high strength low-alloy steel of steel grade Q345. Therefore, we collected more than 20,000 groups of strengths testing data of the steel grades Q235, Q345, which are produced by representative steel mills in China during recent years. Q345 steel property and specification are equivalent to 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.
