Although both HSLA steel plate and carbon steel plate belong to carbon structure and low alloy structure steel, there are some differences. First of all, A514 Gr Q quenched and tempered steel, HSLA steel plate and carbon steel plate differ in strength, hardness and use. In terms of strength, the strength of HSLA steel plate is higher than carbon steel plate. In terms of hardness, the hardness of HSLA steel plate is also higher than that of carbon steel plate. And in the scope of use, the advantages of HSLA steel plate are more prominent, so the scope of HSLA steel plate use is more extensive than that of carbon steel plate.
The company specializes in the research and development, production and sales of A514 Gr Q quenched and tempered steel seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has A514 Gr Q quenched and tempered steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A514 Gr Q quenched and tempered steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
The company has passed ISO quality management system certification, domestic advanced production technology, and high product batch stability. Selected materials, the source controls every quality link to ensure A514 Gr Q quenched and tempered steel product high quality. Use automated, scientific and systematic manufacturing processes to meet the different needs of customers. Become an excellent domestic steel plate manufacturer, serving customers all over the world.
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 Q quenched and tempered steel.
Both parties shall confirm the A514 Gr Q quenched and tempered steel material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the A514 Gr Q quenched and tempered steel steel plant.
