304 stainless steel capillary tube is a precision small-diameter tube manufactured through cold drawing or cold rolling processes. It is widely used in medical devices, instrumentation, electronic components, and automatic control systems where high precision, cleanliness, and corrosion resistance are required. Capillary tubes typically feature outer diameters ranging from 0.3mm to 8.0mm with wall thicknesses as thin as 0.1mm. The 304 austenitic stainless steel grade provides

EN 10305-1 seamless precision steel tubes are cold-drawn seamless steel tubes manufactured to European standard specifications for precision applications. These tubes are characterized by precisely defined dimensional tolerances and specified maximum surface roughness, making them ideal for applications requiring high accuracy and reliability The standard covers circular cross-section tubes with outside diameters up to 380 mm, and may also be applied to other cross-section

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

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

What Is EN 10305-1? EN 10305-1 is the European standard for seamless cold-drawn precision steel tubes. It specifies technical delivery conditions for tubes used in applications requiring close dimensional tolerances, smooth surface finish, and consistent mechanical properties. The standard covers tubes manufactured from various steel grades, with 42CrMo4 being the most popular choice for high-strength, high-pressure components. 42CrMo4 (also known as 1.7225 or AISI 4140) is a
