Q370qC, Q370qD, A131 EH40 ship steel plate and Q370qE are structural steel plates for bridges. It is required to have high strength, toughness and to withstand the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The steel for tie-welding bridges should also have good welding performance and low notch sensitivity. Used for the production of riveted and bolt-welded road bridges and railway bridges (including cross-sea bridges).
The company is committed to providing customers with high-quality and low-cost A131 EH40 ship steel plate steel products as the goal, striving to create value for customers as its own responsibility. With advanced Kaiping processing equipment and strong logistics distribution system, the company can meet the needs of customers at any time. The company has the advantages of A131 EH40 ship steel plate complete specifications, low price and fast distribution, With the service concept of keeping promise and valuing quality, it has won the trust and unanimous praise of the majority of users. The scale and strength of the enterprise is in the forefront of domestic metal material business units.
The wear-resistant plate has the main advantages of high strength and hardness, good toughness, A131 EH40 ship steel plate high tensile strength, good material wear-resistance, long service life and low cost. In order to verify the wear-resistant life of the high wear-resistant composite steel plate applied in the field, the comparative industrial test of A131 EH40 ship steel plate wear-resistant with the ordinary carbon plate was carried out on the reclaimer of Jigang raw material plant, and the effect is good.
The chromium plays an important role in A131 EH40 ship steel plate, Chromium Molybdenum steel. The chromium can form a dense oxide film with strong adhesion on the surface of the steel plate, so as to prevent the internal metal from further oxidation or corrosion. The higher the chromium content in the steel plate, the denser the oxide film, and the better the oxidation resistance and corrosion resistance of the steel plate.
After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
