Stainless steel Because of its durability and rust resistance, stainless steel pipes are widely evaluated in the mining, oil, gas, automotive and aviation industries. So what is the service life of stainless steel?
As long as the protection is proper, the stainless steel pipe can use epoxy resin without any corrosion or rust, so that the stainless steel can be used for a long time. This is because stainless steel is composed of chromium plating, which helps to create a protective layer invisible on the surface, preventing the chromium plating from reacting with the metal and causing oxidation. However, the thickness of this protective layer will vary depending on the grade of stainless steel used. For example, the protective layer of grade 304 stainless steel is thicker than that of grade 430 stainless steel. Even so, stainless steel will affect its service life because of certain factors. The durability of stainless steel depends on: steel grade, environment and surface finish, the most important corrosion consideration is pitting. When assessing point risk corrosion, chloride ions are the most aggressive environmental hazard. Marine sites tend to be the most dangerous, so it has the least durability. The acidic conditions sometimes found in industrial environments are also corrosive. It's also important to consider the impact of the local "microclimate," which influences how harsh the environment can be. Stainless steel pipes also tend to decay faster over time.
Location | Estimated Time to Penetrate 1mm (Years) by steel type | ||
430(1.4016) | 304(1.4301) | 316(1.4401) | |
Marine | N/A | 145 | 260 |
Semi-industrial | 85 | 135 | 525 |
Rural | 250 | 770 | 1200 |
In summary, with proper maintenance, stainless steel can endure extended periods without succumbing to corrosion. Hence, apart from selecting high-quality stainless steel, it is crucial to regularly cleanse and prevent prolonged exposure to acidic or corrosive substances.
