BBN STEEL is a professional enterprise dedicated to Q460E steel plate, with advanced technology and high-quality service! Our company's main products: low temperature resistant Q460E high strength plate, 51crv4 special steel, Q460E low temperature resistant steel sheet, Q460E steel plate. We provide low-temperature resistant Q460E high-strength plates, monthly supply of 2,000 tons of Q460E steel plates in inventory, and full factory direct sales services.

The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, 51crv4 special steel, spring steel must have some characteristics. First, the fatigue resistance of spring steel is good, and it can be restored to its original state after repeated use without deformation. Second, good flexibility. Third, the tensile strength of spring steel is good, under the limit of being stretched, it can be restored without breaking.

51crv4 special steel, 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.

API 5L steel is pipeline steel mainly for use in oil and gas industry. API 5L steel has PSL1 and PSL2 levels. For same API 5L steel grade, the carbon content for PSL1 is higher than PSL2. Meanwhile, the API 5L PSL2 steel has more strict requirement for P, S content than API 5L PSL1 steel, 51crv4 special steel. Therefore, API 5L PSL2 steel strength is higher than API 5L PSL1 steel strength. For example, API 5L X42 PSL2 yield strength is 317-524 MPa, tensile strength is 434-758 MPa. While API 5L X42 PSL1 yield strength is 290 MPa min. , tensile strength is 414 MPa min.

BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the 51crv4 special steel hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.

Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our 51crv4 special steel service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's 51crv4 special steel customer service to establish a good, comprehensive, full service system.
