High-Precision CNC Turned Alloy Steel Parts With Passivation For Construction Machinery

Advantage of Alloy Steel

The advantages of alloy steel are quite remarkable. In terms of performance, it not only has higher strength and better toughness, but also can maintain stability when subjected to complex external forces such as heavy pressure and impact, and is less likely to deform or fracture. Its load-bearing capacity is much greater than that of ordinary steel. During processing, some alloy steels, due to their reasonable composition design, have lower cutting resistance, which can make the processing process smoother and reduce the wear of the cutting tools. Moreover, its application range is very wide. For example, wear-resistant alloy steel can be used in components that undergo frequent friction, anti-oxidation alloy steel can work normally in high-temperature oxidation environments, and cold-resistant alloy steel is suitable for equipment in extremely cold regions, greatly expanding the application fields of steel.

15+ Years of Experience on CNC Machining:

With over 15 years of expertise in CNC machining, JINGXIN—rooted in Dongguan, China—boasts robust capabilities in high-precision custom manufacturing, with a proven track record in projects like high-precision CNC turned alloy steel parts (including passivated components for construction machinery) and far beyond.

Our professional team excels in delivering one-stop solutions through refined manufacturing processes, engineering insights, and meticulous craftsmanship. While we master processing alloy steel—achieving tight tolerances in CNC turning and offering passivation to enhance durability for harsh construction environments—our material expertise extends far wider: we handle stainless steel, aluminum, iron, and more, adapting machining techniques to each material’s unique properties for consistent precision.

Beyond passivation, our surface treatment capabilities cover a spectrum of needs, including anodizing, plating, sandblasting, and coating—tailored to meet corrosion resistance, wear resistance, or aesthetic requirements across industries.

At JINGXIN, we focus on custom non-standard precision components, from hydraulic parts, transmission components, and structural fittings for construction machinery to valves, electric motor parts, sprocket wheels, and medical/electronic pieces. Whatever the material, processing method, or surface treatment need, JINGXIN delivers high-quality results backed by years of technical prowess.
