Buy & Import Cold Drawn Precision Tube for Gas Spring from Taian Henson Metal Co., Ltd. - Wholesale Supply

Cold drawn precision tubes for gas springs from Taian Henson Metal Co., Ltd. are manufactured to DIN 2391, EN 10305-1, ASTM A179, ASTM A192, and ASTM A519 standards. Outer diameters range from 8 mm to 50 mm, with wall thicknesses between 0.5 mm and 50 mm. These tubes are produced via cold drawing or cold rolling, followed by heat treatment in conditions designated as BK, BKS, or NBK to ensure dimensional stability and surface integrity.

The material selection includes SAE1010, SAE1020, #10, #20, #45, 304, and 316 stainless steels, chosen for their machinability, fatigue resistance, and corrosion performance. Tubes for gas springs require high surface hardness and low internal friction. Typical surface roughness is Ra ≤ 0.4 µm, and internal bore is honed to ensure smooth piston movement. The wall thickness range allows for both light-duty and heavy-load applications.

These tubes are primarily used in automotive gas struts, industrial actuators, and medical equipment. Buyers include manufacturers of pneumatic systems, OEMs in the automotive aftermarket, and producers of ergonomic furniture. Minimum order quantities are not specified, but production is optimized for medium-volume runs. Packaging is in protective plastic sleeves with cardboard bundling. Delivery is typically FOB Qingdao or Shanghai. Buyers should confirm heat treatment condition and dimensional consistency per batch.

Frequently Asked Questions About Cold Drawn Precision Tube for Gas Spring from Taian Henson Metal Co., Ltd.
After BKS (stress relieved) treatment, SAE1020 tubes typically achieve a surface hardness of 160 to 190 HV. This ensures resistance to scoring during piston movement. Buyers should request a Vickers hardness test report per batch, as hardness below 150 HV may lead to premature wear in gas spring assemblies.

Sourcing Cold Drawn Precision Tube for Gas Spring from Taian Henson Metal Co., Ltd. - China Import Guide

Verify the material grade, heat treatment condition (BK/BKS/NBK), and surface finish before placing an order. Request a sample with mechanical test data for tensile strength, elongation, and hardness. Confirm that the tube bore is free of burrs and scale, and that wall thickness is uniform along the length. Do not accept tubes without batch traceability or test reports.

Lead time is typically 15 to 30 days for standard sizes and heat treatments. Incoterms are usually FOB Qingdao or Shanghai. Payment terms are commonly 50% advance, 50% against shipping documents. Buyers should confirm packaging includes anti-rust paper and plastic end caps, and request container loading photos to ensure no damage occurs during transit.

Inspection should include dimensional checks with micrometers, surface roughness measurement with a profilometer, and hydrostatic pressure testing for wall integrity. Request a certificate of conformity per EN 10204 3.1. For critical applications, consider third-party inspection at the factory. Retain one sample per shipment for quality audit and warranty claims.
