The company's main steel plates have twelve types of steel products like boilers and pressure vessels, low-alloy high-strength steel A709 grade 50W carbon steel plate, wear-resistant steel plates, corrosion-resistant steel plates, high-rise building structural steel plates, marine structural steel plates, alloy structural steel plates, mold steel plates, carbon structural steel plates, shipbuilding and steel plates for oil production platforms, composite steel plates, steel plates for oil and gas pipelines. We offer various steel grades, and more than 300 kinds of thickness specifications.
Our company was founded in 2000, which initially committed to providing high-quality steel A709 grade 50W carbon steel plate products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export A709 grade 50W carbon steel plate steel to the international market, opening up the international steel market.
The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the A709 grade 50W carbon steel plate product workpiece, thereby improving the production efficiency and production processing quality.
Hydrogen (H) is the most harmful element in general steel such as A709 grade 50W carbon steel plate. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A709 grade 50W carbon steel plate plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
