Normal strength shipbuilding structural steel is divided into four grades: A, B, C, and D. The yield strength (not less than 235N/mm^2) of RA32 oil supply vessel steel these four grades is the same as the tensile strength (400~520N/mm^2). However, the impact properties of steel plates at different temperatures are different.
BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform. The main products are I-beam, angle steel, RA32 oil supply vessel steel , H-beam, hot-rolled coil, welded pipe, spiral pipe seamless pipe and many other steel products. Standing stocks amount to more than 30,000 tons, and complete specifications, the company gradually moves towards large-scale distribution enterprises with serialized products, standardized services and modern transportation management.
In recent years, in line with the development trend of iron and RA32 oil supply vessel steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which RA32 oil supply vessel steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
We have very professional workshops for thin plates/ coils, RA32 oil supply vessel steel, medium and general thick plates. And also special workshop to produce thick plates that thickness is more than 300mm. we produce the steel plate include carbon and low alloy high strength steel plate, shipbuilding and offshore platform steel plate, boiler and pressure vessel steel plate, weather resistant steel plate, pipeline steel plate, alloy steel plate, automobile structure steel plate, and gas cylinder steel coil etc.
