Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the RINA AH36 offshore oil drilling platform steel steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the RINA AH36 offshore oil drilling platform steel weathering steel is purified and the content of inclusions is greatly reduced.
RINA AH36 offshore oil drilling platform steel, Wear resistant steel plate has good wear resistance:The chemical composition of the alloy wear-resistant layer is 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%. The macro hardness is HRC56-62 and the hardness of chromium carbide is HV1400-1800. Because the carbides are distributed perpendicularly in the direction of wear, even when compared with cast alloys of the same composition and hardness, the wear resistance is more than doubled.
We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about RINA AH36 offshore oil drilling platform steel pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.
