Difference between Q235 steel and Q345 steel: First, The lower limit of yield strength of Q235 steel is 235MPa, and that of Q345 steel is 345MPa. Second, Q235 steel is common carbon steel, Q345 steel is low alloy steel. They have different alloy contents. Besides, Q235 steel is for general strength application, Q345 steel is for higher strength application. B480GNQR weathering steel sheet, Q345 steel price is higher than Q235 steel price. But Q345 steel can save materials for sake of high strength.

When using B480GNQR weathering steel sheet, low-alloy high-strength steel, it is desirable to take advantage of its high strength and use a thinner section, not only for saving weight but also for the economy as much as possible. However, the corrosion factor must be fully considered. The thinner the steel section, the more attention should be paid to corrosion protection. Some low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but in some cases, take appropriate precautions and can even be used without being coated in the atmosphere.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
