Q345R steel (16MnR) is a low-alloy high-strength steel. It is a special plate for pressure vessels with a yield strength of 340MPa min. Q345R plate has good comprehensive mechanical properties and technological properties. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 steel (16MnR). In addition to the increased tensile strength and elongation requirements compared to Q345B steel, A572 Gr 50 ms steel coil, the impact toughness is also required.
The company has sufficient inventory and complete varieties and specifications. In line with the sales principle of low price operation and quality first, let customers buy A572 Gr 50 ms steel coil at ease and use it comfortably! Integrity, professionalism and efficiency are our service tenets. We will wholeheartedly provide excellent A572 Gr 50 ms steel coil products and high-quality services for new and old customers. We also sincerely welcome new and old customers to call and write to discuss business and guide work!
We BBN steel company have in-house machining capabilities with excellent machining experience. CNC machining-technology, We provide A572 Gr 50 ms steel coil plate products both conventional and CNC machining services to offer the following machined processes :lathe turning, milling, up to 5 axis cnc, grinding, surface, od and id, threading, single point and grinding, drilling, reaming, and tapping, boring.
The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of A572 Gr 50 ms steel coil, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.
Both parties shall confirm the A572 Gr 50 ms steel coil material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the A572 Gr 50 ms steel coil steel plant.
