液压管

碳素钢 用于汽车应用 无缝的

从1010/1020/1026/1035/1045 ETC碳钢和各种合金等级（例如SAE4130,4140.COLD绘制的无缝（CDS）管具有更接近的尺寸耐受性，比相应的机械性能更高的机械性能）热完成无缝管。特性冷 - 机械管通常会产生OD和壁厚。If the ID is a more important dimension then cold – worked tubing should be specified to the ID and wall thickness or OD and ID Mechanical Seamless Steel Tubing We can supply seamless tubing with specific material/dimensional requirements, depending on customers’ demand.Seamless tubing can be an ideal choice when high strength-to-weight ratio is required and can be processed to provide a combination of desired characteristics, dimensional accuracy, good surface quality, excellent micro–structural uniformity, good machinability and high-tensile properties. Applications: Bushings Spacers Bearings and other mechanical parts in automobiles, aircraft, & drilling equipment Hydraulic Cylinders Automotive Tubular Parts Popular Standards ASTM A519/DIN2391/EN10305 Specification for seamless carbon and alloy steel mechanical tubing Standard Steel Grades 1008, 1010, 1017, 1020, 1026, 1035, 1040,1045 4130, 4140, ST 52.3,ST37.4,E255,E355 Different Final Heat treatment condition: NBK（+N） GBK（+A） BK（+C） BKW（+LC） BKS（+SR） Others available upon request.For more precision application,please consider Cold Drawn Welded Tubes (DOM).
