Cause of corrosion pits on stanag 4569 1 steel used for armored car

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of STANAG 4569 1 steel used for armored car steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main STANAG 4569 1 steel used for armored car production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll STANAG 4569 1 steel used for armored car, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.

09CuPCrNi-A steel is weather resistant steel. It is also called 09CuPCrNi-A weathering steel, or 09CuPCrNi-A anti-corrosion steel. 09CuPCrNi-A steel is equivalent to SPA-H, Corten B, etc. steels. Compared with those steels, 09CuPCrNi-A steel price is cheaper while the performance is similiar. That is mainly because the demands for 09CuPCrNi-A steel is very large in China, which is one of the largest steel prodction and export country. So the production capacity of 09CuPCrNi-A steel in very large in China. Consequently, the unit cost of 09CuPCrNi-A steel is cheaper.

Processing performance of quenched and tempered steel: STANAG 4569 1 steel used for armored car plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.
