Application
As the raw material of seamless pipes, AISI 4140 alloy steel rods have the advantages of high strength, high toughness, and wear resistance, and can meet the use requirements of seamless pipes in various fields. Seamless pipes are widely used in petroleum, chemical, machinery, automobile, aerospace, and other industries to transport various. media such as liquids, gases, and solids.
42CrMo Alloy steel rods are often used to manufacture mechanical parts, such as bearings, gears, drive shafts, connecting rods, etc. Because alloy steel rods have high strength and toughness and can withstand large loads and impacts, they are widely used in the machinery manufacturing industry.
42CrMo Alloy steel rods play an important role in automobile manufacturing. They are used to manufacture key components such as engine crankshafts, camshafts, and transmission shafts. They can provide high strength and wear resistance to meet the working requirements of automobiles operating at high speeds and in harsh environments.

TESTING AND QUALITY CONTROL
Raw material preparation: According to the formula requirements of alloy steel, prepare the required raw materials, including steel and alloy elements.
Smelting: Put the raw materials into the furnace for smelting to reach the alloying temperature so that the alloying elements and steel can be fully mixed.
Casting: Pour molten alloy steel into a casting mold, wait for it to cool and solidify, and then obtain a preliminary alloy steel billet.
Heat treatment: Heat treatment of alloy steel billets, including quenching, tempering, and other processes, to adjust the structure and properties of alloy steel.
Finishing: Finishing the heat-treated alloy steel billet, including forging, rolling, drawing, and other processes, to form it into the required shape and size.
Surface treatment: Surface treatment is carried out on the finished alloy steel rods, including pickling, galvanizing, spraying, and other processes to improve its corrosion resistance and aesthetics.
Testing and quality control: Conduct various tests on the produced alloy steel rods, including chemical composition analysis, mechanical property testing, etc., to ensure that product quality meets standard requirements.
