API 5L Gr. A is mainly used for steel of large diameter pipeline. , API 5L Gr. A is mainly used for pressure liquid transportation, oil, natural gas, water and other liquid transportation, oilfield engineering, pipeline engineering, construction, steel pipe and oil and gas engineering using pipeline.
Cold rolled coil products A572 grade 55 ms steel have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils A572 grade 55 ms steel with different surface roughness can be produced (glossy surface or matte surface, etc.).
A572 grade 55 ms steel,The steelmaking furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the internal quality of the steel.
A572 grade 55 ms steel,Expect in the goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen product development technology, excellent production team, hand strict quality control, sales and after-sales service.
A572 grade 55 ms steel,The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
