Low alloy high strength structural steel is a kind of steel which contains a small amount of alloy elements and is mainly used in construction and engineering structures. Main Chinese steel grades of low alloy high strength structural steel are: Q345A, Q345B, Q345C, Q345D, Q345E, Q390A, Q390B, Q390C, Q390D, Q390E, Q420A, Q420B, Q420C, Q420D, Q420E, Q460C, Q460E, Q500C, Q500D, Q500E, Q550C, Q550D, Q500D, Q620E, Q690C, Q690E, Q345NQR2 tempered steel.

In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate Q345NQR2 tempered steel for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 Q345NQR2 tempered steel and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.

Low-alloy high-strength steel grades are designed to have quite good notch toughness for their intended structural use. The applicability of the notch toughness of specific grades of low-alloy high-strength steel is either based on existing use experience or combined with the results of the impact test of notched specimens. In order to meet the very strict requirements of certain applications, some Q345NQR2 tempered steel, low-alloy high-strength steels produced have excellent notch toughness. For example, controlled hot rolling technology is usually used to produce low-alloy high-strength steel plates for the manufacture of welded line pipes. Such steel pipes need to meet the requirements of relevant standards for notch toughness.

We have a good inventory system because of which the alloy steel plates and structural steel sheets are supplied and delivered to our customers on time. Our alloy steel plate is significantly affordable than austenitic Q345NQR2 tempered steel stainless steel which helps to reduce maintenance and full life costs – as well as improved safety over standard boilerplate.
