In food processing, brewing, pharmaceutical, and catering equipment manufacturing, material safety and hygiene are not just operational requirements—they are legal and ethical obligations. As a trusted supplier of food-grade stainless steel sheet with MTC certificate, we provide materials that meet the most stringent international hygiene and safety standards, giving you confidence in every application.
What Makes Stainless Steel “Food-Grade”?
Food-grade stainless steel must exhibit exceptional corrosion resistance, non-reactivity, and ease of cleaning. The most commonly used grades are:
- 304 Stainless Steel: The most widely used food-contact material due to its excellent corrosion resistance and formability. Ideal for containers, worktables, and kitchen equipment.
- 316 Stainless Steel: With added molybdenum, it offers superior resistance to chlorides and acids, making it suitable for high-salinity or high-acidity environments such as seafood processing, breweries, and dairy plants.
- 430 Stainless Steel: Often used in less corrosive environments or for decorative interior elements where frequent contact with food is not expected.
Each of these grades must have a smooth, non-porous surface finish—typically 2B, BA (Bright Annealed), or polished—to prevent bacterial growth and facilitate sanitization.
The Critical Role of the MTC Certificate
A Mill Test Certificate (MTC) is not just paperwork; it is your guarantee of material identity, traceability, and compliance. For food-grade applications, the MTC provides verified evidence of:
- Chemical Composition: Ensuring the alloy contains appropriate levels of chromium, nickel, and other elements to meet food safety standards and resist corrosion.
- Mechanical Properties: Confirming tensile strength, yield strength, and elongation meet design specifications.
- Surface Quality and Compliance: Certifying the material is produced in accordance with relevant health and safety standards such as FDA (U.S. Food and Drug Administration), EC 1935/2004 (EU), and NSF/ANSI 51.
Without an MTC, you cannot verify that your material is truly food-safe, potentially risking product contamination, equipment failure, and regulatory non-compliance.
