How to choose between 304 threaded rod and 316 stainless steel threaded rod?

When Choosing 304 threaded rods

• Environment: Dry shops and general machinery (no acid or alkali corrosion)
• Advantages: Affordable price, adequate performance, and the best value for money!
• Warning: Strictly check SGS reports! Be wary of counterfeit 201 materials (nickel content < 8% prone to rust).

When 316 threaded rods is essential

• Environment: Coastal/chemical plants/food and pharmaceutical equipment (exposed to salt spray, acids and alkalis, and chemicals)
• Advantages: Molybdenum-enhanced, doubles the corrosion resistance! Although 20% more expensive, it lasts 2-3 years longer, making it a more cost-effective option in the long run! • Case: A coastal equipment used a 304 lead screw, which rusted and became scrapped after 6 months. After being replaced with 316, it ran stably for 3 years!
