- Q235 vs Q345 Strength? | Eng-Tips
The Q345 is stronger as bones206 noted That means that it has a higher yield stress and higher tensile strength Its stiffness (Young's modulus) should be about the same as the Q235 however
- ASTM A572 (US Steel) vs Q345-b (Chinese Steel) | Eng-Tips
Hello, Does anyone have any reference of the steel grade equivalency (ASTM A572 vs Q345-b)? Any document would be greatly helpful especially if there is anything from AISC I looked up the AISC website but couldn't find any Thank you very much in advance
- Q235 vs Q345 Strength? - Mechanical engineering general discussion
Their reply was to replace the existing Q235 steel with Q345, which they claim is nearly twice as strong My problem is that I cannot find anything on the web showing the mechanical properties of these two Chinese steels to verify that this is indeed a good decision Can anyone help with firm information on these two steels?
- ASTM A572 Gr 50 vs Q345B - American Welding Society
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) At the same time, this Contractor says that they, in China, have developed
- SS400 and Q345B - American Welding Society
Does anybody could help and clarify if the Japanese Std steel plates of SS400 is the equivalent of Chinese Std of Q345B?
- What are the commonly available metric plate thicknesses?
We are designing a project outside the US This is the first project that I've worked on where we are using metric shapes, plates, bolts, etc Where can I find a list of commonly available metric plate thicknesses? I searched online but did not find anything definitive The steel will be
- AWS D1. 1 Equivalent steels ( China GB Q235B Q345B)
Hello experts, I have a situation where our fabricator in China using AWS D1 1 WPS PQR I am not a welding expert, so would appreciate advice on structural welding Is impact test mandatory and macro ecth test for PQR qualification as per AWS D1 1 D1 6 ? Which group the materials used ( Q235B Q345B) would fit in according to AWS D1 1 material grouping? Can pipes be covered with same WPS
- PQR for D1. 1 A513 unlisted to A36 but not using A36 in PQR
GB: Q195, Q215, Q235, Q345, L175, L210, L245, L320, L360- L555" Would be interesting to see what is listed on their MTR though I talked with a pipe manufacturer here in the states and was told that ASTM A36 does not cover tube A36 could be rolled into tube but the specification for ASTM A36 does not include tubing or pipe
