Q: What is the main difference between 304 and 430 stainless steel?
A: The primary distinction lies in their chemical composition and intrinsic properties. 304 stainless steel incorporates approximately 18% chromium and 8% nickel, endowing it with exceptional corrosion resistance and heat tolerance, which makes it ideal for applications in the food and medical industries. On the other hand, 430 stainless steel contains about 16-18% chromium and lacks nickel, offering superior processing properties and enhanced thermal conductivity.
Q: Is the product magnetic?
A: No, 304 stainless steel is non-magnetic, ensuring it is suitable for various non-magnetic applications.
Q: What should I be careful about when handling the product?
A: Since the material is metal, handle with care as edges and corners can be sharp, potentially causing injuries. Additionally, the surface is protected by a transparent film that should be removed prior to use to achieve optimal performance.
