SA709 Gr 50 carbon steel material ASTM equivalent steel grade

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 SA709 Gr 50 carbon steel material 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.

The rolling pipe is made by steel plate with welding process. The rolling pipe is mainly used for conveying water, gas, air, oil and hot water or steam, etc. The rolling pipe has the following characteristics. First, it is easy to process. Welding can be done directly on the basis of steel plates, SA709 Gr 50 carbon steel material. Second, the diameter is large, and various large-diameter rolling pipes can be directly customized and processed. Third, the processing speed is fast, saving processing time. Fourth, a small amount of customization can be used for trial proofing to avoid excessive waste.

The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. SA709 Gr 50 carbon steel material, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.

SA709 Gr 50 carbon steel material, Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.
