Carbon steel grade S690QL grade vs stainless steel

On Jan. 31, 2019, BBN steel held the annual meeting with all employees, family members, and friends. It is a moment of joyand it is a moment to summarize the past and look forward.Looking back on 2018, BBN steel exported steel grade S690QL more than 2 million tons of steel materials to all parts of the world and made outstanding contributions to infrastructure construction at home and abroad. In 2019, BBN steel will make persistent efforts and forge ahead.

BEBON is a large steel group with finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. We are committed to creating a various culture system with its own characteristics, and work hard to create a first-class steel plate company in China. Based on the business philosophy of quality-oriented and strengthened management, the company continues to develop in this industry.

steel grade S690QL surface cracks refer to the linear cracks on the surface of steel grade S690QL, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: steel grade S690QL surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.

Structural steel is a category of steel construction material that is produced with a particular cross section or shape, and some specified values of strength and chemical composition. steel grade S690QL, Structural steel plates are normally supplied in the as-rolled condition. Our structural steel plate are supplied with thickness range 3mm to 350mm. The plates may be ordered normalized or stress relieved, or both. steel plates shall be normalized. steel plates and sheets shall be quenched and tempered.

In 2014, we offered 175 ton Cold rolled stainless steel plate to Thailand. The steel grade S690QL products are from TISCO. Here is the MTC that we offered to customer. We have our own quality team. Our quality team will inspect every order before shipment for customer. Normally, we will test the chemical composition, thickness, width, and length. Here are some pictures for last inspection.
