Wuxi Jin Ming Jian De Industry&trade Co., Ltd. supplies AISI 4140 alloy seamless steel tubes, a chromium-molybdenum steel grade known for its high tensile strength and toughness. These tubes are manufactured from alloy steel with a carbon content of 0.38 to 0.43%, chromium at 0.60 to 0.90%, and molybdenum at 0.15 to 0.30%, making them suitable for demanding mechanical and structural applications. The tubes are available in a range of sizes, with wall thicknesses from 2 mm to 200 mm, and are sourced from Jiangsu province, China.
AISI 4140 is a versatile alloy steel grade widely used in oil and gas drilling equipment, automotive drive shafts, hydraulic cylinders, and heavy machinery components. The seamless manufacturing process ensures uniform strength and durability, while the chromium-molybdenum composition provides excellent hardenability and wear resistance. Typical industry standards for these tubes include ASTM A519 for mechanical tubing and API specifications for oil and gas applications.
Primary buyers include manufacturers in the oil and gas, automotive, and heavy machinery sectors, where high strength-to-weight ratios are critical. The tubes are supplied with full mill test certification to ensure compliance with international trade standards. Buyers should confirm specific dimensions, tolerances, and additional certifications directly with Wuxi Jin Ming Jian De Industry&trade Co., Ltd., as these details are not fully specified in the listing.
