The company has superior geographical position and convenient transportation. Our main steel products are: low alloy high-strength plate, carbon structural plate, alloy structural plate, bridge plate, building structural plate, shipbuilding and offshore oil production platform plate, boiler and pressure vessel plate, pipeline plate, weathering steel plate, normal strength hull structural steel GL-B, etc.. In line with the principle of "not striving for the lowest price, but the best quality", the company wholeheartedly provides high-quality steel products and sincere services for users at home and abroad.
40Cr steel belongs to alloy structural steel. normal strength hull structural steel GL-B, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.
As normal strength hull structural steel GL-B, alloy 400 is a kind of metal with good corrosion resistance, it shows good uniform corrosion resistance in the marine atmosphere. This is because alloy 400 can form a very thin and tough protective film. Uniform corrosion is one of the easiest forms of corrosion to deal with, because engineers can quantitatively determine the corrosion rate of metals and accurately predict the service life of metals.
normal strength hull structural steel GL-B, St52-3 steel is a low alloy, high strength structural steel which can be readily welded to other weldable steel. St52-3 steel’s mechanical properties is yield strength more than 355 MPa, tensile strength 490-630Mpa. For St52-3 steel, the C element content is 0.24%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.045% max, the S element content is 0.045% max.
The steel plate, steel pipe and other steel materials are the important material in the material engineers. Our company will provide the high quality the steel plate, steel pipe and other steel materials for you. We are exported the steel plate, steel pipe and other normal strength hull structural steel GL-B steel materials to the customers from USA, South America, Europe, Africa etc. If we can have the good cooperation together, you will be very welcome to be our agent in your local market. Let’s work together!
Both parties shall confirm the normal strength hull structural steel GL-B material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the normal strength hull structural steel GL-B steel plant.
