Key Properties
Corrosion Resistance: Resists oxidation, organic acids, and mild chlorides (e.g., food residues, urban pollution).
Heat Resistance: Stable up to 870°C (intermittent) and 925°C (continuous service in non-corrosive environments).
Non-Magnetic: Austenitic structure remains non-magnetic unless cold-worked.
Hygienic Surface: Passivates naturally, ideal for FDA/USDA-compliant equipment.

Frequently Asked Questions (FAQs)
Q1: How does 304 differ from 316L?
A1: 316L contains 2–3% molybdenum for enhanced chloride resistance (e.g., seawater), while 304 is optimal for general-purpose use.
Q2: Can 304 strips withstand high-temperature processing?
A2: Yes, in oxidizing environments up to 870°C. Avoid prolonged exposure to 450–850°C to prevent carbide precipitation.
Q3: Is 304 suitable for food-contact surfaces?
A3: Absolutely. It complies with FDA 21 CFR 175.300 for indirect contact and is easy to sanitize.
Q4: Why choose 304 over 430 or 201 grades?
A4: 304 offers superior corrosion resistance and ductility compared to 430 (ferritic) and 201 (lower nickel content).
Q5: Can 304 strips be customized for embossing?
A5: Yes. We provide brushed (No. 4), BA, or custom-embossed finishes for branding or anti-slip requirements.
