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. This unique blend endows it with exceptional corrosion resistance and heat tolerance, making it the ideal choice for applications in the food and medical industries. Conversely, 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 highly suitable for various non-magnetic applications.
Q: What should I be careful about when handling the product?
A: Given that this is a metal material, handle with the utmost care as edges and corners can be sharp, potentially causing injuries. Furthermore, the surface is protected by a transparent film that should be removed before use to achieve optimal performance.
