900 tons sa573 gr 70 carbon-manganese-silicon steel shipped to Sri Lanka

The company has a mature technical team whose reponsibility is to design the drawing, choose suitable material and evaluate the whole production processaccording to customers’ requirement. The company is led by talents and technology, and comprehensively promotes its six business segments like steel material supply, precision steel casting, environmental protection equipment, household appliance, sa573 gr 70 carbon-manganese-silicon steel steel structures and oil tank projects. Seeking new developments in new technology and business areas, and fostering a large number of industry-leading, international-level projects.

After quenching and tempering, 40Cr alloy steel plate and sa573 gr 70 carbon-manganese-silicon steel sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel sa573 gr 70 carbon-manganese-silicon steel is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.

During the steel plate cutting, the special-shaped steel plate cutting process is often carried out. In this operation process, some cutting curves will be generated. Therefore, there should be relatively high precision standards during the processing of sa573 gr 70 carbon-manganese-silicon steel. The operators need to have rich experience, and they also need to be proficient in the operation methods and working skills of the equipment, so as to ensure that the steel plate can meet the shape requirements after processing.

The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.
