Now we have been ranked the International leading RINA grade D stern frame steel steel materials supplier.
Under normal exposure to the atmosphere, RINA grade D stern frame steel, bare steel forms a tight protective oxide film during the first few months of atmospheric corrosion. Sometimes architects choose bare steel structures because they want to get the appearance of uniform atmospheric oxidation on the steel surface, and sometimes they are to save the protective coating for economic purposes. To use these low-alloy high-strength steels in a bare state, the design must consider that the surface of the steel cannot be wet for a long time, and special attention should be paid to the special atmospheric environment to ensure that the corrosion rate of the steel is allowed under this condition.
1200 tons API 5LGRB strips to Bangladesh. In December of 2015, we get one tender project from National Tubes Limited, which is a famous national enterprise in Bangladesh. It is an order of 1200 tons API 5L Gr. B steel strips, they bought these cargo to fabricate ERW pipe in local place.
Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, RINA grade D stern frame steel are strict. In the chemical composition of boiler steel, RINA grade D stern frame steel, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.
