offers 1,352 q345 steel equivalent products. About 78% of these are Steel Pipes, 0% are Steel Round Bars. A wide variety of q345 steel equivalent options are available to you, such as technique, grade, and application.

It has come to the attention of the ASTPM that Grade Q345, a standard in China, is being sold into the local market as equivalent to S355. An investigation into Q345, including a number of tests, has resulted in the following conclusions.

Q355 Steel Introduction. Q355 steel is a new Chinese steel grade of 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 levelsQ355B, Q355C and Q355D.. Q is the first letter of Chinese Pinyinqu fu dian, which means Yield Strength, 355 is the minimum value of yield strength 355

Jun 26, 2016 · Q235 is basically a structural steel grade usually used in bridges. Yield strength is somewhere around 423 MPa and Ultimate Tensile strength about 479 MPa. Here are chemical composition of different grades of Q235

May 07, 2013 · Hello everybodyThe 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). At the same time, this Contractor says that they, in China, have developed

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.

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:

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.

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:
