Based on the material characteristics of various components in quick-freezing equipment, 316L stainless steel offers the best overall durability, making it suitable for the vast majority of high-load and highly corrosive quick-freezing applications.
Its resistance to acids, alkalis, and chloride ion corrosion is far superior to that of standard 304 stainless steel; it resists rusting even during long-term use in high-salinity processing environments-such as those handling seafood or cured products-and boasts a service life of over eight years with proper maintenance.
In contrast, 304 stainless steel is suitable only for low-corrosion applications (e.g., processing standard pasta, fruits, or vegetables) and has a service life of approximately five years. Carbon steel is prone to rust and is suitable only for short-term, low-cost use, while ordinary plastics and rubber tend to age and become brittle in low-temperature environments, offering far less durability than stainless steel.
For critical moving parts (such as conveyor belts), 316L stainless steel also offers superior fatigue and deformation resistance, significantly reducing the likelihood of equipment breakdowns and downtime.
