Q235 Steel Plate Equivalent Steel Standard ASTM A36

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 followsDifferent Yield Point (A36=250MPa, Q235B=235MPa); Different Tensile Strength (A36=400 550MPa, Q235B=375 500MPa);Q235 vs A36, SS400, E250, S235JR Steel, Q235A, Q235B The following tables show Q235 steel vs A36, SS400, S235JR and E250 steel, they are similar in chemical composition, mechanical properties, and all belong to carbon structural steels.

Overview of Q235 Steel Plate Specification

Q235 steel is equivalent to Japenese steel grade SS400 in application, the only difference is that ss400 steel requires only S,P composition < 0.050, Q235 has requirements for More element C, Si, Mn, S, P. Yield strength of q235 is >235Mpa, which is almost the same to SS400 245Mpa. Q represents the yield of this material, the latter 235, refers to the yield value of this material, at about 235MPA.Q235 vs Q345 Strength? Structural engineering general Sep 28, 2010· There are also different 4 grades of Q235 and 5 grades of Q345 which have varying carbon content. The PRC Steel Design Code GB 50009 uses a value of E = 206,000 MPa (29,877,774 psi). Perhaps the steel mill in China could provide you with some more specific material data.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 anWhat is Q235 steel grade? QuoraQ235 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
