ASTM A519 4130 Honed Steel Tubing For Hydraulic Cylinder

Description

ASTM A519 4130 Honed Steel Tubing for Hydraulic Cylinders is a seamless steel tube that meets the American Standard. Made from 4130 alloy steel, it is cold-drawn or cold-rolled. It boasts high dimensional precision and excellent surface finish, making it suitable for precision components such as mechanical structures and hydraulic equipment.

ASTM A519 4130 Honed Steel Tubing uses a shaped abrasive to polish the inner surface of the tube to achieve a higher degree of polish and precision. The processing steps for ASTM A519 4130 Honed Steel Tubing primarily include cold drawing, hot rolling, and honing. During honing, shaped abrasives with a grit size slightly smaller than the tube diameter are used to modify the workpiece surface, improving precision and finish.

Features of ASTM A519 4130 Honed Steel Tubing:

High Precision: ASTM A519 4130 Honed Steel Tubing has no oxide layer on its inner and outer surfaces, maintains tight dimensional tolerances, and minimizes ovality, meeting a variety of high-precision applications. High Finish: After honing, ASTM A519 4130 Honed Steel Tubing achieves an exceptionally low surface roughness, typically reaching Ra ≤ 0.08μm, resulting in a remarkably smooth finish.

Wear and Pressure Resistance: The inner surface of ASTM A519 4130 Honed Steel Tubing undergoes a honing process, creating a cold-work hardened layer that enhances wear resistance. Furthermore, honed tubing can withstand high pressures and is less prone to leaks.

Excellent Mechanical Properties: After processing, ASTM A519 4130 Honed Steel Tubing achieves increased surface hardness and strength, resulting in excellent mechanical properties, such as resistance to deformation during cold bending and crack-free during flaring and flattening.

Applications of ASTM A519 4130 Honed Steel Tubing:

ASTM A519 4130 Honed Steel Tubing is widely used in various industries due to its high precision, high finish, and wear and pressure resistance.

Oil and Gas Industry: Used for long-distance transportation of oil, natural gas, and other media, ensuring safe and stable pipeline operation.

Mechanical Manufacturing: As support and transmission components, Hydraulic Honing Steel Pipe‌‘s high precision and smooth surface reduce friction and improve transmission efficiency.

Chemical Industry: Honed tube’s corrosion resistance makes it the material of choice for critical components in highly corrosive chemical environments. Honed tube is also used in industries such as pharmaceuticals to process pipelines and specialized equipment, improving smoothness and interior cleanliness.

Food Processing: Used for fluid transportation, such as in beverage and milk production lines, to ensure food hygiene and safety. Honed tube can also be used to polish the interior walls of food processing equipment to improve equipment hygiene and prevent cross-contamination. Shipbuilding: Honed tubes are widely used in ship hydraulic systems and piping systems due to their high strength and corrosion resistance.

Automotive: Used in automotive engine cooling systems and air intake systems, they can withstand harsh environments such as high temperatures and high pressures.
