What is precision carbon steel and what are its main application fields

2025-07-03


Precision carbon steel processing refers to a high-precision manufacturing process that uses carbon steel (an iron-carbon alloy with a carbon content of 0.05% to 2.1%) as raw material and employs precision machine tools (such as high-precision CNC lathes, machining centers, etc.) for turning, milling, grinding and other processing to achieve dimensional accuracy of IT5 to IT7 and surface roughness Ra≤0.8μm for parts.



The main application fields of precision carbon steel processing

Automotive industry: High-reliability components such as engine crankshafts, transmission gears, and suspension parts.

Aerospace: High fatigue life parts such as landing gear brackets and turbine shafts have extremely high requirements for material uniformity and surface quality.

Machine tool and mold manufacturing: injection mold cores, stamping dies, etc., have strict requirements for tolerances and surface quality.

Medical devices: Surgical instruments, guide sleeves and various precision fasteners, which need to be biocompatible and burr-free.

Precision instruments: optical brackets, measuring probes, sensor housings, have extremely high requirements for shape and position tolerances as well as roughness.
