ASTM A519 무선 스테인레스 스틸 정밀 파이프 4140 냉면 기계식 철강 파이프
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
냉면 무선 스테인레스 스틸 정밀 파이프 밝은 표면 밀착 관용 ± 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
