10 to 20mm thick p355gh steel used for petroleum product: 10*2200*7200, 10*2200*8000, 12*2000*11850, 12.5*2900*11000, 12.9*2987*10384, 13.6*2940*11455, 14*2000*10000, 14*2000*11181, 14*2000*13500, 14*2070*9060, 14*2200*10030, 15*2200*10270, 15*2500*10000, 15*2992*10185, 16*1500*9340, 16*1800*6000, 16*2000*10713, 16*2120*6080, 16*2200*10000, 16*2230*7650, 18.5*2320*6600, 20*1400*11400, 20*2100*7000.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the p355gh steel used for petroleum steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its p355gh steel used for petroleum steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the p355gh steel used for petroleum steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
