We are world class steel materials supplier. We are engaed in providing raw steel materials such as GL-F40 ship building vessel steel steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build GL-F40 ship building vessel steel long-term cooperation with you.
27SiMn steel plate has high strength and wear resistance, high hardenability, good machinability, moderate cold deformation plasticity and weldability. In addition, the toughness of 27SiMn steel does not decrease much during heat treatment, but it has quite high strength and wear resistance, especially when water quenching still has high toughness; but this steel is highly sensitive to white spots and has temper brittleness during heat treatment. Tendency and sensitivity to overheating.
The alloy steel seamless pipe is a kind of product developed on the basis of traditional seamless steel pipe. Some characteristics of the GL-F40 ship building vessel steel, alloy steel seamless pipe are also great progress and optimization based on the traditional seamless steel pipe products. Alloy steel seamless pipe is a kind of high performance seamless pipe. In industrial production, seamless pipe is usually used in pipeline engineering which needs to bear greater pressure.
Wear-resistant steel plate is a kind of construction material with good wear resistance and high toughness. GL-F40 ship building vessel steel, wear-resistant steel plate plays an important role in many industries in daily use. However, what is wear-resistant steel plate? Where is it used? The wear-resistant layer is the main component of the wear-resistant steel plate. The material used to make the wear-resistant layer is mainly titanium alloy. In addition, other materials such as manganese, nickel, molybdenum, and niobium may be added. The coordination of all materials is to maintain or enhance the wear resistance of the wear layer.
Chemical composition of Q390C steel plate: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.7, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.10, Al ≤ 0.015. The mechanical properties of Q390C steel plate are: yield strength ≥ 390 MPa, tensile strength 470-620 MPa, elongation after fracture ≥ 18%, impact energy 34J. GL-F40 ship building vessel steel, Q390C steel plate is used for bridges, vehicles, ships, workshops and other large structural parts, high and medium pressure Petrochemical vessels, boiler tubes, pipes, superheaters, pressure vessels, heavy machinery, etc. application.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate GL-F40 ship building vessel steel EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
Both parties shall confirm the GL-F40 ship building vessel steel 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 GL-F40 ship building vessel steel steel plant.
