Frequently Asked Questions (FAQ) about Jingkong JK20 Corrosion - Resistant Series
Product Foundation and Material - Related Questions
-
What is the core corrosion - resistant material of the JK20 Corrosion - Resistant Series?
The core components of the product that come into contact with the medium are made of high - quality stainless steel. Among them, the corrosion - resistant enhanced version adopts SUS316/SUS316L stainless steel (containing high levels of chromium, nickel, and molybdenum). This material forms a stable passive oxide layer, which endows it with excellent corrosion - resistant performance. It is particularly suitable for environments with chlorine - containing, acid, or alkaline media. Some auxiliary structures can be optionally made of corrosion - resistant engineering plastics such as PP and PVC, further enhancing the all - scenario anti - corrosion capability. -
