Frequently Asked Questions
201 stainless steel contains less nickel and more manganese, making it 20-30% cheaper than 304. However, 201 is only suitable for dry indoor environments, whereas 304 offers superior corrosion resistance (withstanding salt spray tests for over 480 hours) and is food-grade compliant.
You should choose 316L stainless steel for extreme environments, such as marine applications, chemical processing, or medical implants. 316L contains added molybdenum and lower carbon, providing exceptional resistance to chloride ions (up to 10,000ppm) and intergranular corrosion.
430 stainless steel is a nickel-free ferritic alloy that offers excellent thermal conductivity (26.1 W/m·K) and low thermal expansion. It is highly resistant to thermal fatigue and can be shaped via high-speed stamping with minimal work hardening, making it highly cost-effective.
Yes, our 304 stainless steel fabrication processes comply with GB 4806.9 food-grade standards. We utilize hydraulic forming and electrolytic polishing (achieving roughness Ra≤0.1μm) to produce parts suitable for food contact and medical applications.
We specialize in a wide range of precision fabrication services, including laser cutting, CNC bending, wire drawing, TIG welding, high-speed stamping, hydraulic forming, auto-riveting, sandblasting, and electrolytic polishing/passivation.
