Frequently Asked Questions (FAQ)
Q1: What is the main difference between 201 and 304 stainless steel in fabrication?
201 stainless steel is a cost-effective alternative containing lower nickel and higher manganese, making it ideal for indoor, dry decorative applications. 304 stainless steel has higher nickel content, offering superior corrosion resistance and food-grade compliance (GB 4806.9) suitable for kitchens, medical environments, and outdoor use.
Q2: Why is 316L stainless steel preferred for marine and medical applications?
316L stainless steel contains 2-3% Molybdenum (Mo) and ultra-low carbon (C≤0.03%). This chemical composition prevents intergranular corrosion during welding and provides high resistance to pitting and chloride-rich environments like seawater, chemical reactors, and biocompatible medical implants.
Q3: Can 430 stainless steel be used for magnetic components?
Yes, 430 is a ferritic stainless steel that is naturally magnetic. Due to its excellent magnetic properties, high thermal conductivity (26.1 W/m·K), and lower cost (nickel-free), it is widely stamped and fabricated for appliance parts, automotive components, and EMI shielding panels.
Q4: What custom fabrication services does Mingli Metal offer?
Mingli Metal offers comprehensive sheet metal fabrication solutions, including fiber laser cutting, CNC bending, hydraulic deep drawing, high-speed stamping, TIG welding, auto-riveting, wire drawing, sandblasting, and electrolytic polishing.
Q5: How does Mingli Metal ensure quality compliance for different grades?
We strictly test and certify our fabricated parts based on application requirements. This includes ISO 12944 indoor durability for 201 steel, NSF and food-grade contact standards for 304 steel, and ISO 5832-1 implant standards for 316L medical components.
