The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable LR grade D seafaring ship steel steel 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 market and has strong competitiveness.
Available steel plates: carbon structural steel, low-alloy high-strength steel, steel plates for bridges, steel for building structures, steel angles for shipbuilding and offshore platforms, steel sheets for boilers and pressure vessels, LR grade D seafaring ship steel steel plates for molds, steel plates and strips for alloy structures, corrosion-resistant steel, wear-resistant steel, pipeline steel for oil and gas transportation.There are more than 300 domestic and foreign steel grades in our supply list.
Just as LR grade D seafaring ship steel, the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness. The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects. In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed.
Our company has the ability to produce all kinds of steel structure parts. At the same time, we can design drawings according to the requirements of customers, and process according to the drawings. LR grade D seafaring ship steel Heat treatment services - such as annealing, normalizing, quenching, tempering, quenching and tempering, solution treatment, etc. We can also heat treat according to customer's LR grade D seafaring ship steel requirements.
The quality grade of common carbon structural steel Q235 can be divided into A, B, C, D and E. Relatively, the quality of Q235A is poor and that of Q235E is the highest. Different grades of Q235 steel have different characteristics, which are mainly different from the impact temperature: Q235A does not require impact toughness test; grade Q235B is for room temperature (20℃); grade Q235C is for 0℃; grade Q235D is for - 20℃; grade Q235E is for - 40℃. The LR grade D seafaring ship steel, carbon structural steel Q235 has good combination of strength, plasticity and welding properties.
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.
