Durable, rust-resistant, and versatile, it’s perfect for construction, equipment assembly, and DIY projects requiring long-length fasteners.
Product Description
01 Why does stainless steel also have magnetism?
304 stainless steel is austenitic stainless steel. During cold working, part or a small amount of austenite transforms into martensite (which is magnetic). Therefore, 304 stainless steel is non-magnetic or weakly magnetic. For details, you can search "why 304 stainless steel has magnetism" on Baidu.
02 How to identify genuine 304 stainless steel products?
- Use a special test solution for 304 stainless steel: if it doesn’t change color, it’s genuine 304 stainless steel.
- Support chemical composition analysis and spectral analysis.
- Support smoke testing to simulate actual usage environments.
03 What are the common types of stainless steel?
- 201 stainless steel: Suitable for dry environments; it rusts easily when exposed to rainwater.
- 304 stainless steel: Applicable to outdoor or humid environments, with high corrosion and acid resistance.
- 316 stainless steel: Has stronger corrosion and acid resistance, especially suitable for seawater and chemical media.
