FAQs

Q1: What is the main difference between 304 and 304L stainless steel?
A1: 304L has lower carbon content than 304, which makes it better for welding without risking intergranular corrosion.

Q2: Is 304 stainless steel food-safe?
A2: Yes, it is one of the most commonly used stainless steels in food preparation and storage equipment.

Q3: Can I use 304L stainless steel outdoors?
A3: Yes, it’s suitable for outdoor use in mild environments. For marine or high-chloride environments, 316 is preferred.

Q4: What’s the best finish for decorative use?
A4: Mirror and HL finishes are most popular for elevators, wall panels, and public-facing architectural features.

Q5: Do you offer customized cutting or polishing?
A5: Yes. Gengfei offers precise cutting, surface treatment, and PVD coloring based on your project needs.
