The chemical composition of RINA grade B corrugated bulkhead steel

The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.

SA387Gr5Cl2 steel material is suitable for refining and gas treatment in hydrogenation and conversion equipment at high temperature. The maximum thickness of RINA grade B corrugated bulkhead steel, SA387Gr5Cl2 steel plate can reach 250mm. According to different thickness and impact requirements, the heat treatment of SA387Gr5Cl2 steel plate is normalizing plus tempering or normalizing plus rapid cooling plus tempering. By using special smelting method, the content of phosphorus is reduced so that sa387 has high brittleness resistance and good impact toughness at low temperature.

In actual processing applications, the processing RINA grade B corrugated bulkhead steel thickness of flame cutting ranges from 6 to 200 mm, and the RINA grade B corrugated bulkhead steel cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting RINA grade B corrugated bulkhead steel with a certain thickness above 10mm.

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 RINA grade B corrugated bulkhead steel 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 RINA grade B corrugated bulkhead steel 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.
