ASTM A519 ống chính xác thép không gỉ liền mạch 4140 ống thép cơ khí kéo lạnh
What Is ASTM A519? ASTM A519 is the American standard for seamless carbon and alloy steel mechanical tubing. It covers tubes manufactured for use as mechanical components, hydraulic cylinders, and precision-machined parts – not for fluid transport under pressure (that would be ASTM A179 or A213). The standard specifies requirements for: Chemical composition Mechanical properties Dimensional tolerances Heat treatment options ASTM A519 Seamless Precision Steel Tube is produced
Ống thép không gỉ liền mạch nguội có độ chính xác Bề mặt sáng Dung sai chặt chẽ ± 0,03mm
Cold drawn seamless precision pipe is manufactured from solid billet through a process of piercing and cold drawing, resulting in no weld line, uniform wall thickness, and excellent dimensional accuracy. Compared to welded tubing, it offers superior pressure resistance and structural integrity, making it ideal for high-reliability applications. Key Features: No weld seam – homogeneous structure Tight tolerance: OD/ID up to ±0.03mm Smooth surface finish: Ra ≤ 0.4μm Enhanced
