Grade alloy steel Q500NH machinability

On March 19, 2020 the us international trade commission (ITC) vote on imports from China and India's carbon alloy alloy steel Q500NH steel screw (Carbon and Alloy Steel Threaded Rod) to make a positive final anti-dumping and anti-subsidy industry damage. All five members of the international trade commission voted in favor of the ruling. The us department of commerce will issue anti-dumping and countervailing duty orders on imports of alloy steel Q500NH carbon alloy steel screws from China and India, according to the itc's affirmative ruling.

The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.

Composite steel plate is a composite steel plate which is made of carbon steel or low alloy steel as the base material and coated with stainless steel, titanium alloy, alloy steel Q500NH and other composite materials, or sandwiched with other metal or non-metal materials between two layers of steel and processed by pressure or blasting. It is mainly used to make chemical equipment and chemical storage tank, or obtain special functions such as shock absorption. The manufacturing methods of composite steel plate include rolling method and explosion method, but most of them are rolling method.

In December of 2015, our regular India customer sent us an inquiry for alloy steel Q500NH pipe. The inquiry requires no negative tolerance in both pipes’ outer diameter and pipe wall. After two weeks’ discussion, he put the order of 275 tons to us. The pipes are finished within just one month. Our customer come to our factory to inspect the quality and tolerance, all the products are well meet his demand. The pipes are arriving to Nhava Sheva port, customer is very happy with our products and service during the process.

The toughness of steel such as alloy steel Q500NH is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.

alloy steel Q500NH, 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.

The company attaches great importance to the value of iron and steel, constantly improving itself in terms of attitude, innovation, human resources, etc., integrating the value of iron and steel into the company's philosophy, showing the spirit of fighting for alloy steel Q500NH iron and steel, forging iron and steel enterprise, creating steel market, establishing iron and steel team, and attaching importance to the sustainable development of iron and steel industry, so as to make iron and steel our permanent cause.
