  • Q235 material is in accordance with PRC standard GB 700 and Q345 is in accordance with GB 1591. I have translated copies of these standards but theExcellent, so this means the Q345 is a ballpark average of around 50% stronger. I'm ok with that. The Q235 did the job so I can live with this Q3Ian, If deflection is the source of your problem, a higher strength steel will not fix it. You will need to add stiffness to the piece to limit tI don't really know that I agree sme75, in the past when I've had similar deflection problems switching to a higher strength steel has solved the pThe Q345 is stronger as bones206 noted. That means that it has a higher yield stress and higher tensile strength. Its stiffness (Young's modulus) sHow does the Modulus of Elasticity compare for the two steels? Probably about the same. The paint did not peel off in a high stress area, so bad pI too am now very curious how the two modulus' compare. IanIanI agree with BA's last post, and would add that if paint were going to be cracking and chipping due to high stresses it would be at the weldsI follow you dhengr. I drew attention to the powder coating popping off because this happened right as the lift attempted to lift this heavy loadI don't think the Young's modulus will differ much from that of other mild steels (29,000 30,000 ksi). There are also different 4 grades of Q235 an
