Product Description
Classification of stainless steel
Stainless steel can be divided into three categories: 400 series, 300 series, and 200 series. The 300 series is the most commonly used in daily production and life. Within a certain range, the 400 series and 200 series are substitutes for the 300 series. It contains nickel elements, not stainless steel but stainless iron, so it can be attracted by magnets. The 200 series and 300 series have nickel, so they are not magnetic and cannot attract iron.
Advantages of stainless steel products
1. Environmental protection: It can effectively reduce environmental pollution.
2. Corrosion resistance: stain resistance, acid resistance, corrosion resistance, wear resistance, no radioactivity.
3. Surface cleaning: the surface of the product is smooth and compact, not easy to be polluted by dust, with good self-cleaning.
4. Easy maintenance: Easy to repair minor damage.
Bars are widely used in construction, machinery, automobiles, ships and other industrial fields, 70% of which are used for construction, and the rest are used for various shafts, bolts, nuts, anchor chains, springs and other materials. Therefore, the development of the iron and steel industry is of great significance. my country is a developing country, housing still needs a lot of development, and the demand for construction steel will be very high for a long time. In addition, with the improvement of people's living standards, the corresponding demand for automotive steel will also increase. In addition to the direct application of threaded steel bars in buildings, a considerable part is processed into various shaft parts.
Bar use
The modern national economy contains many sectors, such as industry, agriculture, transportation, construction, commerce, health, etc., which are all important components of the national economy. The metallurgical industry is an important part of modern industry. The metallurgical industry provides high-quality raw materials for the machinery manufacturing industry, and the machinery industry in turn can provide excellent mechanical equipment for other industries
