Many people choose stainless steel products because of the "stainless" in their name, believing it will never rust. Therefore, when they discover brown rust spots on their stainless steel sinks, spoons, or outdoor railings, they are often surprised and confused: "Did I buy fake stainless steel?"In r

Stainless steel isn't a single material; it's a vast family encompassing hundreds of different alloys. Choosing the wrong stainless steel grade can lead to equipment corrosion, product contamination, structural failure, and even significant economic losses and safety risks. Therefore, scientifically

Introduction: How do three series of stainless steel build the foundation of modern industry step by step?

420J2 stainless steel is a martensitic stainless steel (corresponding to Chinese grade 3Cr13), belonging to the 400 series stainless steel, which optimizes the balance between corrosion resistance and hardness by adjusting the carbon (C) and chromium (Cr) content. It mainly improves mechanical prope

300 series stainless steel contains chromium, nickel and molybdenum as its main components. It has excellent corrosion resistance, heat resistance and oxidation resistance, and is non-magnetic or weakly magnetic. The 400 series stainless steel mainly contains chromium and manganese and does not cont
