SM490B is a structural steel produced according to Japanese standard JIS G3106, with a strength σb of 490MPa. This standard applies to bridges, ships, vehicles, petroleum storage tanks, manufacturing plants, general construction and various engineering machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, and excavators used in mines and various engineering constructions.

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.

The main function of boron in BV DH32 oil tanker steel and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
