Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the EN10025-4 steel S355M project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of EN10025-4 steel S355M customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

16 Mn is a major steel grade of high strength low alloy steel plate in most industries, The consumption of this type is very large. Its intensity is higher than the ordinary EN10025-4 steel S355M carbon structural steel Q235 by 20% ~ 30%, atmospheric corrosion resistance by 20% ~ 38%.

Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous EN10025-4 steel S355M process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.

EN10025-4 steel S355M, 15CrMo alloy steel is Chinese material. It is characterized by high Chrome and Molybdenum contents. The 15CrMo alloy steel chrome content is 0.80-1.10, and molybdenum content is 0.40-0.55. Besides, 15CrMo carbon content is 0.12-0.18, silicon content is 0.17-0.37, manganese content is 0.40-0.70. The heating temperatures for quenching and tempering of 15CrMo alloy steel are 900 and 650 centigrade respectively. The yield point of 15CrMo alloy steel is 295Mpa.

Management information and high efficiency. Because of the rapid flow of EN10025-4 steel S355M goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation

our company is leading supplier of API 5CT casing pipes in China. N80 oil casing pipes enjoy high size precision, good weld toughness, EN10025-4 steel S355M good extrusion resistance, easy quality control and low cost features. Welcome to our company to purchase EN10025-4 steel S355M API 5CT N80 and so on casing pipes.
