The company is a large NV B cargo ship steel steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the NV B cargo ship steel enterprise, and make our own contribution to the development of the world economy.
Low carbon steel is a carbon steel with a carbon content of less than 0.25%. Low carbon steel NV B cargo ship steel is also called soft steel or mild steel because of its low strength and low hardness. Low carbon steel includes most common carbon structural steel and a part of high-quality carbon structural steel, most of which are used for engineering structural parts without heat treatment, and some NV B cargo ship steel are carburized and other heat treated for mechanical parts that require wear resistance.
The alloy layer of clad wear-resistant plate is mainly made of chromium carbide, and it is also equipped with molybdenum, niobium, titanium, boron and other components. The formation of multi-element carbides also has strong stability at high temperatures and can still be maintained below 500 °. High hardness and good oxidation resistance. The new clad wear-resistant plate NV B cargo ship steelhas multiple performances of wear resistance, corrosion resistance, temperature resistance and impact resistance.
Oxygen (O) is a harmful element in steel such as NV B cargo ship steel. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.
Chemical elements of 42SiMn steel: C: 0.39-0.45, Si: 1.10-1.40, Mn: 1.10-1.40. Mechanical properties of 42SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 40; impact energy: 47J. 42SiMn steel belongs to alloy quenched and tempered steel with good properties, high strength, wear resistance and hardenability. Under certain conditions, the strength, wear resistance and hot working performance of 42SiMn steel are better than 40Cr steel, NV B cargo ship steel, and can be used instead of 40CrNi steel.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled NV B cargo ship steel plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive NV B cargo ship steel industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel NV B cargo ship steel product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue. We promise all our steel materials are manufactured and tested in accordance with responding standards. We will take full responsibility for the quality of the steel materials we provide.
