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.

SA573 Grade 70 steel for marine engineering product is a low-alloy high-strength steel that adds a small amount of alloying elements to general steel to make it have corrosion resistance in the atmosphere. Weathering steel has 2-8 times the atmospheric corrosion resistance of ordinary carbon steel, and the longer the service time, the better the corrosion resistance. In addition to excellent weather resistance, weathering steel also has excellent mechanical and welding functions.

SA573 Grade 70 steel for marine engineering, Q355GNH weather resistant steel plate is one of our main product, it is belong to the weather resistant steel plate. We can supply the different sizes of Q355GNH weather resistant steel plate. And the rolling size of Q355GNH weather resistant steel plate is following: the thickness range is 1.2-150mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the Q355GNH weather resistant steel coil thickness should not exceed 25 mm.

The Performance requirements of low alloy structural steel, SA573 Grade 70 steel for marine engineering:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.

Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.

The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate SA573 Grade 70 steel for marine engineering after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our SA573 Grade 70 steel for marine engineering steel mill.
