Pipeline steel plays an important role in pipeline transportation. How many types of ASTM A588 heavy plate, pipeline steel are there? At present, pipeline steel can be divided into the following four categories according to microstructure. First, pearlitic pipeline steel. The basic components of pearlitic pipeline steel are carbon and manganese, generally speaking, the content is 0.10% - 0.20%, and the manganese content is 1.30% - 1.70%. It is generally produced by hot rolling or normalizing heat treatment process. Second, acicular ferrite pipeline steel. Third, martensitic pipeline steel. Fourth, tempered sorbite pipeline steel.
Heat treatment advantages of ASTM A588 heavy plate, SA516 Gr 70 pressure vessel steel: 1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased. 2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness. 3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition. 4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.
Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in ASTM A588 heavy plate steel. Manganese has a strong ability to deoxidize and remove sulfur, it can eliminate or reduce the hot brittleness caused by oxygen and sulfur, and improve the strength and hardness of ASTM A588 heavy plate steel.
S355NL steel plate is under EN10111 standard. We can regard ASTM A588 heavy plate, S355NL steel plate as Fine-grain structural steels, normalised rolled. S355NL steel plate is one mainly of Fine-grain structural steels, normalised rolled, The normalized rolled fine-grain structural steel S355NL is characterized by a minimum yield strength of 355 MPa, by good weldability and high resistance to brittle fracture, which is same with DIN:TStE355 and BS:55EE
