The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the A514 Gr E high strength steel plate industry, keep pace with the times, and move towards a new course!
GB/T1591-2018 Q355NB is a low-alloy high-strength structural steel. This steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Steel A514 Gr E high strength steel plate products are delivered in hot rolled, normalized, normalized rolled or thermomechanical rolled (TMCP) state.
X56 steel plate is a kind of steel mainly used for large-diameter pipelines. API X56 steel plate is used to manufacture buried pipelines for natural gas transmission. Due to the corrosion of soil, serious degradation will occur. The corrosion type of X56 steel plate that can be produced is usually general corrosion and pitting. we are API 5L X56 steel suppliers ,we also can supply API 5L X52,API 5L X60,API 5L X65,API 5L X70,API 5L X80,please contact us if you need.
The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the A514 Gr E high strength steel plate product workpiece, thereby improving the production efficiency and production processing quality.
42CrMo alloy steel A514 Gr E high strength steel plate: low temperature tempering welding performance thermal processingThe heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
