What stainless steel grades prevent corrosion from manure fertilizers?
Manure fertilizers are highly corrosive due to their acidic and saline nature, making material selection critical for agricultural equipment. Among stainless steel grades, 316 stainless steel is a top choice for its excellent resistance to chloride and acidic environments, thanks to its molybdenum content. For even harsher conditions, 2205 duplex stainless steel offers superior strength and corrosion resistance, combining austenitic and ferritic properties. These grades outperform standard 304 stainless steel, which may pit or corrode over time. When designing equipment like storage tanks or spreaders, opting for 316 or 2205 ensures longevity and reduces maintenance costs in manure-heavy applications. Always prioritize proper passivation and regular cleaning to maximize corrosion resistance.
