This is a reminder to all our fastener users:
Environmental factors: Although 304 stainless steel has good general corrosion resistance, in an environment containing high concentrations of chloride ions (such as sea water, salt spray, chemical media), it is easy to undergo brittle fracture if it is subjected to tensile stress at the same time.
Material upgrade: In the harsh environment mentioned above, 316/316L stainless steel (containing 2% molybdenum) or duplex stainless steel (such as 2205) are safer choices, and they are more resistant to chloride ion stress corrosion.
For high-corrosion risk scenarios such as coastal buildings, chemical plants, and shipbuilding, Shuifu Hanyang Machinery Technology provides professional corrosion-resistant fastener selection solutions:
Material Options: Regularly stocked in 316, 316L, 310S and 2205 duplex stainless steel.
Surface treatment (optional): For special needs, we can also provide PTFE (Teflon) coating to further isolate corrosive media.
Before shipment, we will specifically mark the usage environment restrictions in the accompanying documents for special-purpose orders, and remind customers of installation torque and anti-corrosion precautions to avoid losses caused by misuse.
