The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced EN 10025 S355ML/NL production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, EN 10025 S355ML/NL steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.

Weathering steel alloys like Corten A/B were developed for hard-wearing industrial applications to eliminate the need for costly finishing and refinishing. Primary alloying elements in the steel (copper, chromium, and nickel) actively cause atmospheric corrosion at the surface to generate a hard, corrosion-resistant patina. This protective layer actively and continuously regenerates when Corten steel EN 10025 S355ML/NL is subjected to weathering influences, including airborne pollutants, humidity, and rain.

Different form EN 10025 S355ML/NL, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.

For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In EN 10025 S355ML/NL, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.

A588 Grade A steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness."When propertly exposed to the atmosphere, A588 Grade A is suitable for many applications in the bare condition. EN 10025 S355ML/NL, A588 Grade Acould be produced in 200mm in our company.

The alloy steel plate is among our business scope, and it is one of our main product. If you have any demands or questions about alloy steel plate, such as 34CrMo4 EN 10025 S355ML/NL material properties, 42CrMo4 AISI equivalent, 12Cr1MoV equivalent ASTM, 40Cr material specification, 42CrMo hardness, 50CrMo4 chemical composition and so on, please free free to communicate with us. We have professional technical team and sales team, who will give you EN 10025 S355ML/NL professional answers and quotation about alloy steel plate in time.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
