Good quality A588 Grade B structural shapes with low cost

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, A588 Grade B structural shapes.Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business A588 Grade B structural shapes department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and A588 Grade B structural shapes after-sales service department constitute the service customer network.TMCP process is an indispensable technology for our production of low alloy high strength wide and A588 Grade B structural shapes thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy A588 Grade B structural shapes and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.With the increase of temperature, the yield limit of A588 Grade B structural shapes will decrease monotonically, but the tensile strength of A588 Grade B structural shapes will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of A588 Grade B structural shapes. Near the blue brittleness temperature, the A588 Grade B structural shapes strength increases and the plasticity decreases. The elongation and section shrinkage of A588 Grade B structural shapes increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
