What Are The Differences between Lead Screw of Different Materials?

What are the differences between lead screw of different materials?

1.Core Differences Comparison

1.1Corrosion Resistance：

Stainless Steel: Contains chromium (at least 10.5%) which forms a passive film, providing strong resistance to moisture, acid, and alkali corrosion, making it suitable for high-humidity environments such as kitchens and bathrooms.

Carbon Steel: Prone to rusting, relies on surface coatings (such as paint or galvanization) for protection, which may lead to corrosion over time if the coating deteriorates.‌

‌

1.2 Strength and bearing steel:  

Stainless steel: Slightly lower in strength but more flexible, it is entirely adequate for everyday kitchen organization.

Carbon steel: High carbon content provides superior hardness and strength, making it suitable for high-load scenarios such as heavy tool storage.

‌

1.3 Cost and Maintenance:

Stainless steel has a higher initial cost but a longer lifespan and is maintenance-free, making it more cost-effective in the long run.

Carbon steel is cheaper (about one-third the price of stainless steel) but requires regular maintenance to prevent rust.

‌

2.Recommended application scenarios: 

Choose stainless steel for environments with frequent contact with water and oil (such as kitchen shelves, bathroom racks). Opt for it if you seek aesthetics (modern look, easy to clean) or food-grade safety (like 304 stainless steel).

Choose carbon steel for dry environments, limited budgets, or high-load requirements (such as garage tool racks).

3.Other Considerations:

Weight: Carbon steel is heavier and more difficult to install and move.

Appearance: Stainless steel maintains a long-lasting silver sheen, while carbon steel comes in various colors but can appear old quickly.

Conclusion: If the budget allows and the environment is damp, stainless steel is the better choice; if cost-effectiveness or high strength is the priority, carbon steel is more suitable. It is recommended to prioritize materials like 304 stainless steel or galvanized carbon steel that offer a balance of properties.
