Pipeline steel A514 Gr P high strength steel plate refers to the hot rolled coil plate or wide thick plate used to transport oil, natural gas and other large-diameter welded steel pipes. In the process of using pipeline steel, it is required not only to have high compressive strength, but also to have high low temperature toughness and excellent welding performance. Pipeline steel plates are used to make oil and gas pipelines. The main A514 Gr P high strength steel plate pipeline steel grades are API 5L grade B, API 5L X42, API 5L X60, API 5L X65 and so on.
The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. A514 Gr P high strength steel plate, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.
The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for A514 Gr P high strength steel plate.
Main A514 Gr P high strength steel plate production plants: Wugang, Baosteel, Laiwu Steel, Angang, Baotou Steel, BBN Steel, Katalor Industry Pressure vessel plates are used to manufacture steel plates for steam boilers, pressure vessels and other pressure vessel structures. Because this kind of steel plate is subjected to certain air pressure and water pressure, and the use environment of different temperatures, such as high, medium and low temperature, etc., the requirements for this kind of steel plate are relatively strict.
The high strength A514 Gr P high strength steel plate low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of A514 Gr P high strength steel plate ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
