The Q235 did the job so I can live with this Q3 q345b yield strengthIan, 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 t q345b yield strengthI 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 p q345b yield strengthThe Q345 is stronger as bones206 noted. That means that it has a higher yield stress and higher tensile strength. Its stiffness (Young's modulus) s q345b yield strengthHow 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 p q345b yield strengthI too am now very curious how the two modulus' compare. IanIan: I 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 welds q345b yield strengthI follow you dhengr.
