The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel ASTM A573 steel sheet products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the ASTM A573 steel sheet market and has strong competitiveness.
Marine steel plates are classified as medium-thick plates, hot-rolled steel plates used for manufacturing hull structures produced in accordance with the requirements of the classification society. First, the toughness of the marine steel ABS Grade A, ASTM A573 steel sheet, ABS EH36 plate is the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.
904L corrosion-resistant steel is developed with various sulfuric acid corrosion applications. 904L corrosion-resistant steel has high chromium content and enough nickel content. The addition of copper makes 904L corrosion-resistant steel have strong acid resistance, especially to chloride gap corrosion and stress corrosion cracking, and its pitting corrosion resistance is slightly better than other steels, such as ASTM A573 steel sheet.
In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This ASTM A573 steel sheet production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate ASTM A573 steel sheet size.
As for Q460 series low alloy steel, there are three quality Grade C, D, E. ASTM A573 steel sheet, Q460C steel plates are mainly used in various large-scale engineering structures and light-weight structures that require high strength and large load. Q460C steel mechanical properties: Q460C yield strength MPa in different thickness: ≤16mm: ≥460; 16-40mm: ≥440; 40-63mm: ≥420; 63-80mm: ≥400; 80-100mm: ≥400; 100-150mm: ≥380. The tensile strength MPa: 550-720.Elongation: ≥17%.Impact test: 0 ℃ impact test: ≥34J.
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.
