Low alloy steel plate, refers to the steel plate whose alloy content is less than 3.5%. The most popular low alloy steel plate is CCS EH40 hull shell steel, Q345B plate and its equivalent materials such as S355JR, A572 grade 50 and so on. Low alloy steel plate plays an important role in the construction, it must have enough strength and stability to bear the safety of the house. Low alloy steel plate is often used in large buildings with large bearing capacity and good cross-section stability, such as bridges, ships, lifting and transportation machinery, etc.
S235JR steel plate is one mainly of Carbon and low alloy steel, S235JR steel plate is a type of steel sheet under EN standard which is used to build ship, bridge, belongs to high strength sheet. EN10025-2 S235JR is equivalent to DIN:ST37-2,JIS:SS400,ASTM:A283C, GB Q235B and UNI:FE360B.
There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than CCS EH40 hull shell steel, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.
BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For CCS EH40 hull shell steel ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the CCS EH40 hull shell steel standard requirements. The company is a good ASTM A572 Grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel CCS EH40 hull shell steel plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
