Stainless Steel Gears - Frequently Asked Questions
Q: What makes stainless steel gears better than regular steel gears?
A: Stainless steel gears offer superior corrosion resistance, making them ideal for wet or chemically aggressive environments. They maintain dimensional stability better than carbon steel when exposed to temperature variations and don't require protective coatings that can wear off over time. While slightly more expensive initially, stainless steel gears typically demonstrate lower total cost of ownership due to extended service life.
Q: How do I choose between 304 and 316 stainless steel gears?
A: 304 stainless steel gears are suitable for most general applications with moderate chemical exposure. Choose 316 stainless steel gears when operating in marine environments or when exposed to chlorides, acids, or other aggressive chemicals. The molybdenum content in 316 provides enhanced pitting resistance. For food processing or medical applications, we recommend 316L (low carbon variant) for superior cleanability and corrosion resistance.
Q: What maintenance do stainless steel gears require?
A: Stainless steel gears require significantly less maintenance than carbon steel gears. Regular inspections for wear and proper lubrication are recommended. Use food-grade lubricants when appropriate. Avoid lubricants with chlorinated additives as they can cause stress corrosion cracking. Periodic cleaning with mild detergents (no chloride cleaners) helps maintain corrosion resistance. Proper alignment during installation prevents premature wear.
