Precision CNC Stainless Steel Machining Services
Stainless steel alloy contains chromium element to form a dense anti-rust passivation film on surface, featuring permanent corrosion resistance, high tensile strength and high temperature resistance. It is widely used for parts requiring long service life under humid, chemical or saline working environments.
HONGWEN supplies full-series stainless steel precision CNC machining, including 304, 316L, 17-4PH, duplex stainless steel. We support micro precision medical parts and large industrial structural component processing with ±0.005mm tolerance, covering medical, food, marine, aerospace and electronic industries.
