The use of Q355NH CE maximum

With the development of China's Q355NH CE maximum market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of Q355NH CE maximum products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

A633Gr.C,D steel plate A537CL1/A633Gr.C,D steel plate, under ASTM-SAE standard A537CL1/A633Gr.C,D steel plate, under ASTM-SAE standard, we can regard Q355NH CE maximum, A537CL1/A633Gr.C,D steel plate as Fine-grain structural steels, normalised rolled steel. A537CL1 steel plate is one mainly of Fine-grain structural steels, normalised rolled steel,A537CL1/A633Gr.C,D steel plate is under ASTM-SAE standard equivalent to DIN:TStE355, EN:S355NL, which with a minimum impact energy of 20J at temperatures not lower than -20 degree and the tensile strength of A537CL1/A633Gr.C,D is 4800 to 620 MPa.

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from Q355NH CE maximum. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.

Ultrasonic flaw detection emits ultrasonic waves to the Q355NH CE maximum steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the Q355NH CE maximum steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in 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.
