3m X 6m X 150mm S690QL yield Plate

The difference between q345 and q235 steel S690QL yield
The lower limit of yield strength of Q345 is 345MPa (the actual meaning of Q is the Chinese character ""qu"", and the standard value behind means the lower limit of yield strength). Q235 steel is used for metal structural parts, nitrided or cyanidized parts with low core compressive strength requirements, support rods, crankshafts, crane hooks, couplers, bolts and nuts, sleeve specifications, shafts and weldments.

We are world class steel S690QL yield materials supplier. We are engaed in providing raw steel materials such as steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for S690QL yield quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build long-term cooperation with you.

We do sand blasting and shop primer for various S690QL yield steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer S690QL yield thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.

Chromium element (Cr element) can improve the strength and hardness of S690QL yield, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

There is a careful, patient, enthusiastic and thoughtful after-sales team, a professional distribution, ultra-efficient warehouse and logistics center, a marketing team with marketing expertise, an innovative technology center with strong steel technology, an experienced manufacturing center with rigorous professionalism Quality Inspection Center, an operation team with many years of administrative management experience. Such a strong combination of teams makes BEBON a steel giant in Henan Province.
