Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the A514 grade C alloy steel plate hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the A514 grade C alloy steel plate steel industry.
Hull structural steel is divided into general thickness and high-strength steel. General strength steel is divided into four grades of A, B, C and D; high-strength steel is divided into two strength grades and three quality grades; AH32, DH32, EH32, AH36, DH36, A514 grade C alloy steel plate, EH36. In order to ensure quality and ensure sufficient toughness of hull structural steel, the chemical composition of Mn / C is required to be above 2.5, and the carbon equivalent is also strictly required. Our Hull structural steel plates can be supplied with certificates from different classification societies.
Q345R material is a special steel grade for pressure vessels with a yield strength of 340MPa. It has good comprehensive mechanical properties and technological performance. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 (16Mn) steel. In addition to the increased tensile strength and elongation requirements compared to Q345 (16Mn) steel, it also requires impact toughness. Q345R steel plate is currently the most widely used and most used steel plate for pressure vessels in China.
Quenching Improve the hardness of A514 grade C alloy steel plate steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of A514 grade C alloy steel plate steel and comprehensive mechanical properties.
Our company supply various size and thickness A514 grade C alloy steel plate, hot rolled plates. Plate thickness is available ranging 3mm to 350mm. Steel coils thickness are supplied in max. 25mm. Tolerances for carbon steel coils for conversion to: For minimum gauge orders, thickness and width tolerances are in accordance with the respective ASTM specifications of A568 for thicknesses of less than 0.230 inches(exclusive), and A635 for thicknesses of 0.230 inches to 1.00 inch, inclusive.
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
