　　Nickel based alloy 800 stainless steel rodThe main alloying elements are chromium, molybdenum, tungsten, and also contain small amounts of niobium, tantalum, and indium. In addition to its wear resistance, it also has good oxidation resistance, corrosion resistance, and welding performance. It can be used to manufacture wear-resistant components and also as a coating material, which can be coated on the surface of other substrate materials through welding and spraying processes. Soft magnetic alloys, including nickel based soft magnetic alloys, nickel based precision resistance alloys, and nickel based electric heating alloys, are glassy alloys containing about 80% nickel. They have high maximum and initial magnetic permeability, low coercivity, and are important iron core materials in the electronics industry. The main alloying elements of nickel based precision resistance alloys are chromium, aluminum, and copper. This alloy has high electrical resistivity, low temperature coefficient of resistivity, and good corrosion resistance, and is used to make resistors. Nickel based electric heating alloy is a nickel alloy containing 20% chromium, which has good oxidation and corrosion resistance and can be used for a long time at temperatures of 1000-1100 ℃

The positive effects of supply side structural reforms such as reducing production capacity on the steel industry in one direction are gradually fading away. As mentioned earlier, the continuous integration of Baowu and private enterprises has led to the continuous expansion of the scale of individual steel groups. A group of steel companies have achieved multi base operations with a production capacity of over 20 million tons, and the industry's competitive landscape has been upgraded to the "*" stage. The production capacity threshold of "30 million tons+" for the top steel group is looming. In the fields of special steel and stainless steel, leading companies with production capacity exceeding 10 million tons, such as CITIC Special Steel and Qingshan, have also emerged.

The company relies on the production advantages of major steel enterprises, strives to advance, explores and innovates, and continuously deepens its cooperation with steel enterprises. Greatly reduce procurement costs, improve customer ordering cycles, and enhance service quality. Seize the market and gain an advantage for customers. We can also customize seamless steel pipes according to customer needs, and cut semi-finished and finished steel cutting parts on behalf of customers. The company will continue to strive and To provide you with high-quality service.
