Technical key points of SA633 Gr C carbon steel plate sheet production

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product SA633 Gr C carbon steel plate sheet structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel SA633 Gr C carbon steel plate sheet supplier in the world.

Difference between Q235 steel and Q345 steel: First, The lower limit of yield strength of Q235 steel is 235MPa, and that of Q345 steel is 345MPa. Second, Q235 steel is common carbon steel, Q345 steel is low alloy steel. They have different alloy contents. Besides, Q235 steel is for general strength application, Q345 steel is for higher strength application. SA633 Gr C carbon steel plate sheet, Q345 steel price is higher than Q235 steel price. But Q345 steel can save materials for sake of high strength.

Strip steel is coiled and curved steel plate, which is different from common steel pipes and steel plates. Strip steel has obvious characteristics. First, it is thin and easy to curl, which is convenient for logistics and transportation. Second, the surface quality of SA633 Gr C carbon steel plate sheet, strip steel is good, the luster is bright and it has good flexibility. Third, the strip steel is easy to process. When you need to use it, you only need to straighten the bent part and you can directly process it. Fourth, the precision is high, and the strip steel can be made of plain carbon steel, carbon structure steel, spring steel, tool steel, stainless steel, etc.

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like SA633 Gr C carbon steel plate sheet, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

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, SA633 Gr C carbon steel plate sheet. 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.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the SA633 Gr C carbon steel plate sheet principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
