BBN is a big team with great centripetal force. The company adheres to the tenet of "creating value for customers, creating benefits for enterprises, creating wealth for employees, and creating prosperity for society". Adhere to the strict management of factories, technology-oriented, adhering to "standard management, adhere to integrity, the pursuit of excellence, pragmatic innovation "Business philosophy, we are committed to creating a full-process, low-cost, high-quality, green and environmentally friendly stainless steel manufacturing enterprise.

ASTM A 242 GR. 1 steel plate, sa573 gr 70 high strength structural steel, A 242 GR. 1 steel plate, under ASTM standard, we can regard A 242 GR. 1 steel plate as Steel Resistant to Atmospherical Corrosion A 242 GR. 1 steel plate is one mainly of Steel Resistant to Atmospherical Corrosion, A 242 GR. 1 steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.

Titanium microalloying is an element of sa573 gr 70 high strength structural steel strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in sa573 gr 70 high strength structural steel tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

The hardness of sa573 gr 70 high strength structural steel, wear-resistant steel plate is an important standard to measure wear resistance. The hardness of wear-resistant steel plate can be divided into microhardness and surface hardness. The microhardness of carbide in the wear-resistant layer of wear-resistant steel plate can reach over HVl700-2000, and the surface hardness can reach HRC58-62. Chromium alloy is the main wear-resistant layer of wear-resistant steel plate, and other alloy components such as manganese, molybdenum, niobium, nickel are added at the same time.

Due to the surge in business volume in recent years. In addition to coordinating our own truck fleet, our logistics department has continuously developed high-quality logistics companies and signed long-term cooperation agreements. While enjoying the professional and fast service of logistics companies, we have significantly reduced transportation costs. That not only ensure our customers receive the goods at the same time, but also help them reduce shipping costs.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate sa573 gr 70 high strength structural steel EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
