Cold temperatures and spring bars?

[hampal]

I'm using a blue-ox sway-pro WDH. I was wondering if cold temperatures can affect either the spring bars or chains. I don't normally tow in the coldest part of the year but this year I will. We'll be leaving PA for FL in late December and coming back in mid January. Bitter cold temperatures are not uncommon here during that time I'd hate to experience a failure when leaving or coming home. I normally hitch up the day before we leave too so its possible the steel could be exposed to single digits overnight, for the first full day of towing, and the last day when we come home.

Have you ever heard of steel spring bars shattering due to cold and if so what precautions can I use?

If it matters, these spring bars and chains are 3 1/2 years old.

Mild steel becomes brittle at about -50F. There are many different alloys, though, and we would need to know what specific alloy Blue Ox uses for the WD bars. I'm not an engineer but I suspect they could withstand temps far below single digits.

Never heard of one breaking because of cold, Car and truck springs are made form similar materials and they don’t shatter at that temperature so I would think the spring bars on a WDH would be fine.
