STAINLESS STEEL KNOWLEDGE
1️⃣ Why is stainless steel sometimes magnetic?
Most stainless steel products are non-magnetic. However, some materials, such as stainless steel wire ropes, may develop slight magnetism during production. Therefore, judging stainless steel quality solely based on magnetism is not scientific.
2️⃣ How to identify genuine stainless steel products?
✔ Use stainless steel testing solution for verification.
✔ Analyze the chemical composition with a spectrometer.
✔ Conduct a salt spray test to simulate real-world corrosion resistance.
3️⃣ The most commonly used stainless steels:
201 stainless steel – Suitable for indoor environments.
304 stainless steel – Suitable for outdoor environments.
316 stainless steel – Suitable for coastal or marine areas.
