CUSTOMER  Q & A--




 

**01 Why is stainless steel sometimes magnetic?**  

304 stainless steel is an austenitic stainless steel. During cold processing, part of the austenite transforms into martensite. Martensite is magnetic, which is why 304 stainless steel is generally non-magnetic or only weakly magnetic. For details, search online for "Why is 304 stainless steel magnetic?"  

---

**02 How to identify authentic 304 stainless steel products?**  

1. Use **304-specific testing solution**: No color change indicates authentic 304 stainless steel.  
2. Conduct **chemical composition analysis** or **spectral analysis**.  
3. Perform a **smoke test** to simulate real-world usage conditions.  

---

**03 What are the common types of stainless steel?**  

1. **201 stainless steel**: Suitable for dry environments; prone to rusting when exposed to rain.  
2. **304 stainless steel**: Ideal for outdoor or humid environments due to high corrosion resistance, acid resistance, and strength.  
3. **316 stainless steel**: Offers superior corrosion and acid resistance, especially suitable for seawater and chemical environments.
