What is the minimum safety factor used for alloy steel chains?

• A. 2 to 1
• B. 3 to 1
• C. 5 to 1
• D. 4 to 1

Answer: (D)

The minimum safety factor for alloy steel chains is four to one. This means the chain’s breaking strength should be at least four times the maximum load it’s expected to carry. This margin accounts for dynamic or shock loading, wear and elongation, misalignment, and other real-world conditions that can reduce strength. A factor as low as two or three would not provide enough protection against these risks, while five to one is more conservative than the minimum standard.
