Prime quality SA573 Grade 70 steel grade mechanical properties

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

The alloying elements of low alloy steel are less than 5%. The low alloy steel is added one or several alloy elements on the basis of carbon steel to improve the performance. Such as manganese, silicon, aluminum, nickel, copper, boron, phosphorus, rare earth, etc. SA573 Grade 70 steel grade Steel with one or more of these elements will have the advantages of high strength and toughness. Due to the addition of few alloy elements, it is called low alloy high strength steel.

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, SA573 Grade 70 steel grade. 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.

SA573 Grade 70 steel grade, Q345B low alloy steel has outstanding characteristics, such as:
First, Q345B low alloy steel has good toughness. It is easy to bend and stretch, not easy to break, and can be used for multiple processing. Second, SA573 Grade 70 steel grade, Q345B low alloy steel is easy to weld and can be used for assembly. Third, Q345B low alloy steel has good strength, good compression resistance and long service life. Fourth, the weather resistance of Q345B low alloy steel is good, and the use is not affected whether it is winter or summer.
