Extreme heat conditions
The strength of all chains is adversely affected by heat and care must be exercised when using chain slings at elevated temperatures.
Where the temperatures are likely to be higher than 200°C
it will be necessary to derate the usual WLL.
MAX-ALLOY Gr8 chains and fittings do not require periodic heat treatment and must never be reheat-treated other than by McKinnon Chain.
McKinnon Alloy 800 slings should not be galvanised or subject to other plating processes without the express approval of the manufacturer. Please contact you Mckinnon Alloy distributor for detailed recommendations.
Chain and attachements should not be used in an acid or other corrosive enviroments. If a sling is inadvertently exposed to acid or alkali, even for a short period, it must be withdrawn from servise and referred to McKinnon Chain.
