XIAYI Heat-Treated Shock Absorber Bolt is a precision limit fastener developed for shock absorber piston rod reciprocating movement, damping valve positioning, and hydraulic stroke limitation. It is manufactured from 40Cr alloy steel and processed through four-section integrated cold forging, vacuum quenching and tempering, precision turning, thread rolling, and multi-layer anti-corrosion passivation.

XIAYI High-Tensile Steel Flange Bolt is a Grade 10.9 fastening solution developed for automotive suspension connections exposed to repeated impact, vibration, and high tightening loads. It is manufactured from 40Cr alloy steel and produced through controlled cold forging, vacuum quenching and tempering, precision thread rolling, flange finishing, and multi-layer galvanizing and passivation.

XIAYI Cold Drawn Precision Steel Tube is manufactured in accordance with GB/T 3639-2021, focusing on dimensional accuracy, material consistency, surface quality, and mechanical performance. It is developed for applications where conventional steel tubes may create problems during machining, sealing, welding, or precision assembly.

XiaYi High Strength Precision Steel Tube is developed for applications where load-bearing capacity, fatigue resistance, dimensional stability and structural reliability are critical. Manufactured in accordance with GB/T 3639-2021, it uses high-purity 20# carbon steel and a controlled protective-atmosphere heat treatment process to achieve a balance between strength and toughness.

XiaYi Seamless Precision Steel Tube is designed for applications where tube integrity, internal surface quality and dimensional stability are critical. Manufactured according to GB/T 3639-2021, it uses seamless forming, precision cold drawing and CNC inner honing to produce a weld-free tube structure with consistent wall thickness and a smooth internal bore.

XiaYi High Strength Precision Welded Steel Tube is developed for precision components that require stable weld integrity, controlled dimensions and reliable forming performance. Manufactured according to GB/T 13793-2016, it uses Q235B hot rolled strip and automatic high-frequency resistance welding to create a consistent straight-seam tubular structure.
