High strength RD 40 hull steel plates for tube

Automobile steel sheet is mainly used to manufacture automobile girders (longitudinal and cross girders), frame and other structural parts. The automobile girder should not only bear heavy static load, but also bear certain impact, vibration, etc., so the steel sheet RD 40 hull steel plates is required to have certain strength and fatigue resistance, as well as better stamping performance and cold bending performance to meet the requirements of cold stamping processing.We will return our customers with zealous service attitude, high quality products and favorable price. We have been accumulating, perfecting, developing and expanding constantly. We have huge RD 40 hull steel plates steel products stock. We have won the trust and support of our customers with high-quality service and excellent product quality. The company adheres to the development concept of honesty and win-win cooperation. We are willing to form an alliance with like-minded partners to work together for development and common progress.TMCP process is an indispensable technology for our production of low alloy high strength wide and RD 40 hull steel plates 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 RD 40 hull steel plates 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 RD 40 hull steel plates will decrease monotonically, but the tensile strength of RD 40 hull steel plates will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of RD 40 hull steel plates. Near the blue brittleness temperature, the RD 40 hull steel plates strength increases and the plasticity decreases. The elongation and section shrinkage of RD 40 hull steel plates 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.First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
