New breakthrough of BBN hydrogen chromium molybdenum steel plates

Recently, 137-142 mm thick low Si chromium molybdenum steel plates of BBN steel were successfully delivered to customers, which will be used in heavy crude oil processing project.

The qualified rate of flaw detection and surface of this batch of hydrogenated chromium molybdenum steel plates reaches 100%, and the manufacturing cycle is shortened by 14 days compared with the industry level, indicating that the industrial mass production level of the product has reached the industry leading level.

Previously, BBN successfully produced 172 mm chromium molybdenum steel plates with unit weight of 49.58 tons to replace the imported steel plates for the project. The thickness and unit weight are the highest of similar steel plates, which has helped the petrochemical industry to realize the localization of this type of steel plates.

The large thickness chromium molybdenum steel plates occupy a leading position in the petrochemical industry and coal chemical industry steel field, with a high market share. With the increasingly stringent technical requirements of customers in recent years, and the trend of large-scale development of equipment in the petrochemical industry, technological innovation to promote material upgrades and meet industry steel needs has become the main direction of BBN large-thickness chromium-molybdenum steel product research and development.
