A871-65 is an HSLA structural steel plate with improved athmospheric corrosion resistance that’s also known as a weathering steel.
A871 weathering steel comes in 2 different grades including grades 60 and 65. To meet mechanical requirements, 871 steel plate can be provided in the as-rolled, normalized, or quenched and tempered conditions.
When A871 is properly designed, it can be used bare, without paint, for many applications. It has very good corrosion resistance comes at a higher price point than other steel plates.
A871 steel is used in tubular structures and poles where the atmospheric corrosion resistance is a must. Some examples are:
A871 can be machined in the annealed condition, but will have better results when the condition is H1150M.
A871 can be welded by common fusion and resistance methods, but should not be joined by oxyacetulene welding.
A871 is heat-treatable.
