Agricultural steel is a kind of special steel mainly used for mechanical parts, agricultural machinery and tools, tools for soil cultivation, etc., and is generally referred to as carbon tool steel and alloy tool steel.
Carbon tool steel is one of the most widely used steel materials at present, and its main functions are cutting, punching and shearing. Commonly used carbon tool steels mainly include medium carbon steel and high carbon steel. The commonly used medium carbon steel is 65 manganese steel, medium carbon steel, medium carbon steel with vanadium, medium carbon steel with chromium added and so on. The commonly used medium carbon steel has excellent cutting performance, good surface hardening and crack resistance, good hardenability and machinability, and moderate toughness. The commonly used high-carbon steel is the most widely used in carbon tool steel, because of its low cost and good processing performance.
Alloy tool steel is mainly used to make cutting tools and measuring tools. These tools have excellent wear and toughness and can be used for a long time under certain processing conditions. Commonly used alloy tool steels include Cr-W steels, Cr-Si steels, high speed steels and molybdenum series alloys. Cr-W steel is an alloy containing Cr and W. The performance of Cr-W steel is superior to that of carbon tool steel and is mainly used to make complex and precise tools that require high wear resistance. Cr-Si steel is mainly used to make tools for high-speed steel and cold-work die steel. High speed steel contains about 1.6% to 2.5% of W, 4.0% to 6.5% of Mo, 4.0% to 6.5% and V, and a small amount of Ni, Co and other alloying elements. Such steels have excellent cutting performance and hardness and are mainly used to make cutting tools. Molybdenum series alloys contain molybdenum and tungsten. The combination of these two elements can form carbide in the steel matrix, which has excellent heat resistance, wear resistance and oxidation resistance.
Agricultural steel has a wide range of uses, mainly in agricultural machinery and tools, such as ploughs, harrows, cultivators, hoes and agricultural implements. In order to adapt to the different soil, climate and agricultural work intensity of different regions and countries, agricultural steel must meet the following requirements: First, the surface of agricultural steel should be smooth and solid, firm and firmly connected, and no weak link parts should appear. Second, the surface of agricultural steel should be uniform, without defects, and the weld should be full and firm. Third, the weld geometry of agricultural steel should be accurate according to the requirements, and all welds should be inspected for qualification after welding. Fourth, the bending and welding performance of agricultural steel should meet the requirements of the relevant national standards. Fifth, the surface hardness of agricultural steel should reach the requirements of the relevant national standards. Sixth, the surface of agricultural steel should meet the requirements of the relevant national standards.
Agricultural steel is a kind of special steel mainly used in agriculture and agriculture related industries. It has strong tensile strength, good toughness and excellent wear resistance. In order to ensure its quality, agricultural steel must meet strict national standards and the requirements of relevant industry. At the same time, the surface treatment of agricultural steel should also meet the requirements of anticorrosive and rust prevention, so as to ensure its long-term use in the specific environment.
Agricultural steel is a very important part of agricultural production, and it should be used correctly and maintained regularly in agricultural production and construction. In production and construction, people should choose the steel products with good surface finish and uniform performance, and the surface of steel products should meet the requirements of anticorrosion and rust protection. People should also pay attention to the maintenance and inspection of agricultural steel products to prolong its service life.
As an important part of agricultural production and construction, agricultural steel should be treated with care. When used, people should select the steel products with excellent surface performance, so as to ensure the high-quality operation of the entire agro-mechanization system. Meanwhile, people should also be aware of the maintenance and regular inspection of agricultural steel products, because the quality and performance of agricultural steel products will be directly related to the safety and effectiveness of agricultural operations.
In summary, agricultural steel is a kind of special steel mainly used for mechanical parts, agricultural machinery and tools, and tools for soil cultivation. In order to ensure the quality and performance of agricultural steel, people should choose qualified products and pay attention to the maintenance and inspection of agricultural steel products. The correct and standardized use of agricultural steel will ensure the high-quality and efficient operation of the entire agricultural production system.
