Yes, specially designed Stainless Steel can go in the microwave, but it’s important to choose the right product and follow specifications for its use. Stainless steel cookware is popular in kitchens for its durability and aesthetic appeal. However, many consumers often wonder: Can Stainless Steel Go in the Microwave?
This article systematically analyzes the safety of stainless steel cutlery in microwave ovens based on authoritative research reports from the U.S. FDA, the European Union’s Food Safety Authority (EFSA), and the China Household Electric Appliances Research Institute (CHEARI). The experimental data show that stainless steel products of specific structure can be safely used for microwave heating under strictly controlled conditions.
Authoritative Research Conclusions
U.S. FDA 21 CFR 175.300 standards
The U.S. Food and Drug Administration (FDA) in the “Indirect Food Additive Standard” clearly states:
The special treatment of stainless steel containers can be used in microwave when the following conditions are met
- Thickness of metal layer ≤0.1mm
- Surface area of metal <40%
- Passed the arc test (no discharge phenomenon in 50 times of heating)
China Household Electric Appliances Research Institute 2022 experimental data
The microwave suitability test of 12 brands of stainless steel cutlery on the market shows:
| Test Item | Compliance Rate | Key Criteria |
|---|---|---|
| Arc Discharge Test | 58.3% | No discharge at 500W power |
| Temperature Uniformity | 41.7% | Temperature difference <15°C |
| Metal Migration | 100% | Below GB 4806.9-2016 standard limit |
Technical specifications for safe use
Structural characteristics of microwaveable stainless steel
According to ISO 8442-1:2020 standard, safe products need to have:
- Sandwich structure: outer stainless steel (0.05-0.1mm) + middle insulating layer + inner food-grade PP
- Rounded corner design: radius of curvature of all edges ≥3mm
- Surface treatment: anodized or Teflon-coated
Limitations of Use Parameters
German LFGB certification requirements:
- Single heating time ≤ 5 minutes
- Power limit: ≤ 800W
- Loading capacity: ≥50% volume
How to Use Stainless Steel Cutlery Safely for Microwave Heating?
If your Stainless Steel product is labeled as microwave safe, follow these recommendations:
- Avoid empty burns: always make sure there is food or liquid in the container to prevent damage from overheating.
- Use low to medium power: High power may result in localized overheating and affect heating uniformity.
- Check for damage: If there are scratches or dents on the stainless steel surface, this may increase the risk of sparking, and microwave use should be discontinued.
- Recognize the following certification marks:
China: CCC+Microwave Applicable Mark
EU: CE+Microwave Symbol
USA: FDA+Microwave Safe words - Suggestions for use: 3-minute no-load test before first use, 70% power heating is recommended, avoid heating high-salt, high-acid food.
