If A 515 grade 70 pressure vessel plates thick in 50mm or under this thickness, CCS F40 hull steel plates, A515 Grade 70 plates are supplied in the as-rolled condition. Normalizing treatment can be ordered, but those greater than 2 inch (50 mm) in thickness must be delivered in normalizing state. A515 Gr 70plate and sheet are widely used in petroleum, chemical industry, power station, boiler and other industries. It is used to make reactor, heat exchanger, separator, spherical tank, paint tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum.

On August 29th Clients from Senegal visited us-Zhengzhou office and wanted to know more about BBN to build a long relationship. They have a big demand of ship building steel plates with thickness 6mm and thickness 8mm LR AH36 shipping steel CCS F40 hull steel plates plates to Senegal Navy, and our strong advantage in offering these ship building steel plates make us begin to build a steady cooperation relationship with Senegal clients. BBN has always supplied high quality ship plates with stable supply. Soon he placed 15 containers of LR AH36 shipping steel plates to BBN.

NM500 wear plate is Chinese abrasion resitant steel. NM500 steel is equivalent to AR500, HARDOX500, XAR500 and so on materials. The surface Brinell hardness of NM500 wear plate is ≥470 HBW. The NM500 steel is consists of max. 0.38% Carbon, 0.70 Silicon, 1.70 Manganese, 0.020 Phosphorus, 0.010 Sulfur, 1.20 Chrome, 1.00 Nickel, 0.65 Molybdenum, 0.050 Titanium, 0.0005-0.006 Boron, min. 0.010 Als, etc.. According to GBT24186, the max. thickness of CCS F40 hull steel plates, NM500 wear plate is 70mm.

At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, CCS F40 hull steel plates, and there are relatively few cracks and holes. After 25 days, delamination occurs in some parts of carbon steel and weathering steel, and there is no difference in corrosion products, mainly due to the role of alloy elements in the rust layer. The precipitation of Cu and Cr alloy elements in the weathering rust layer can resist the invasion of moisture and harmful ions in the atmosphere, and further corrosion of steel and base metal can be prevented, so as to achieve the effect of atmospheric corrosion resistance.
