Q235B Carbon Structural Steel Plate. 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:Different Yield Point (A36=250MPa, Q235B=235MPa); Different Tensile Strength (A36=400-550MPa, Q235B=375-500MPa); Different element content requirements:(A36:C is equal to or less than 0.25%, Si is less than or equal to 0.4%, P < 0.04%, s is less than or equal to 0.05%; Q235B Q345B (GB ) - Worldwide equivalent grades - Steel NumberChemical composition and properties of european equivalents (EN) for Q345B (China, GB ):S355JR (1.0045) , Q345B (China, GB ) - European (EU, EN) and wordwide Steel equivalent grades. These comparison table is only intended as an indication of the closest khown equivalent grades. The source standarts should always be checked for the specific S235 S275 S355 STEEL PLATE - Gnee steelProduct introduction. Gnee steel is able to supply all kinds of structural steel plate produced by En10025-2 standard, which mainly includes 4 major grades:S235, S275, S355 and S450, there's also more specific steel grades for different mechanical properties. As same as common structural steel, steel plate and pipes under this standard are
In contrast, the mechanical properties of the steel Q235B are far superior to that of the material Q235A. In general, the steel works are marked on the logo before the finished Q235 steel plates are out of the factory. The user can identify the material on the label as Q235A steel plates, or Q235B steel The difference between Q345 and Q235 - YaangSep 08, 2016 · 2, the two different alloy content:A:Q235 ordinary carbon steel, Q235 is carbon steel, Q235-- metal structure, the center of strength less demanding carburizing or cyanide parts, rod, rods, hooks, coupler, bolts and nuts, set cylinder, shaft and weldments. B:Q345 low-alloy steel, Q345 low-alloy structural steel, Q345-- good mechanical properties, low temperature performance can, good gb t q235a beam channel chemical composition - SIPLA Our products mainluy contain gb t q235a beam channel chemical composition, Carbon Steel Plate and Alloy Steel Plate, Bolier steel Plate, Wear Resistant Steel Plate, Ship-Building Steel Plate, Corten Steel Plate and so on.We can cut into any width and length for you.If you need punch a hole,we can also do it.
