Does the material of the pin need to be corrosion-resistant
Yes, the pin material needs to be corrosion-resistant in specific environments. If the pins are exposed to corrosive environments such as dampness, Marine conditions, chemical acids and alkalis, or food processing, the material must have anti-corrosion capabilities; otherwise, it will lead to rust, reduced dimensional accuracy, failed fit, and even shortened equipment lifespan.
Key material selection suggestions
Highly corrosive environments (such as Marine equipment, chemical machinery) :
304 stainless steel : salt spray resistance > 96 hours, moderate cost, suitable for general corrosive scenarios.
316 stainless steel : containing molybdenum, it has stronger resistance to acid and alkali corrosion and is suitable for harsher working conditions.
Galvanized carbon steel : as an economical alternative, it can withstand salt spray for over 1000 hours and is suitable for non-food grade equipment.
Food/medical equipment :
A1 grade stainless steel : complies with food grade standards, surface electrolytically polished to Ra≤0.8μm, ensuring hygiene and safety.
Ordinary dry environment :
Carbon steel (such as 45 steel) or alloy steel can meet the requirements and no additional anti-corrosion treatment is needed.
In conclusion, the selection of corrosion-resistant materials should be based on environmental assessment: prioritize stainless steel to enhance reliability and lifespan.
