Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and NV B cargo ship steel heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported NV B cargo ship steel to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
15Mo3 steel is a kind of pearlitic heat-resistant steel, which can still show its characteristics under high temperature and long time load. 15Mo3 steel is used for heating surface of NV B cargo ship steel low and medium pressure boiler (working pressure is generally not more than 5.88MPA, and working temperature is below 450 ℃). 15Mo3 steel is widely used in petroleum, chemical industry, power station, boiler and other industries. 15Mo3 steel is used to make reactor, heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, etc.
The tensile strength of seamless steel pipe is more than 8-10 times of that of ordinary steel, and its elastic modulus is better than that of steel, with excellent creep resistance, corrosion resistance and seismic resistance; the mechanical performance of seamless steel pipe is excellent, easy to machine, etc.; the seamless steel pipe NV B cargo ship steel is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.
NV B cargo ship steel, Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.
Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of NV B cargo ship steel, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).
The company is mainly engaged in NV B cargo ship steel steel plates manufacturing and deep processing, sales and distribution. It is committed to building a complete modern steel purchase and sale network. Here we would like to express our sincere gratitude to our old and new friends who have always given care, support, affirmation and help, and sincerely hope to establish a long-term cooperative relationship with them for mutual benefit, win-win and common development, and work NV B cargo ship steel together for a better tomorrow.
Our company will accept the product quality objection registration record, pass it to the NV B cargo ship steel production unit and relevant departments, and timely coordinate the supervision of product NV B cargo ship steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
