ABRASION RESISTANT STEEL

Abrasion Resistant Steel Plate and Sheet is intended to meet the requirements for a low cost abrasion resisting steel. It is a high carbon manganese-silicon steel with better workability than carbon steel of the same hardness range. With proper practice this steel can be cut, welded, drilled, rolled formed and machined. Dependent upon the type of wear (i.e.impact loading, grinding, sliding or cutting) and nature of the material handled, A.R. Steel will last from 2 to 10 times longer than ordinary structural steel. The atmospheric corrosion resistance is equal to structural carbon steel.

A.R. Steel is supplied from our stocks in the as rolled condition and further expensive heat treatment is not required to develop its abrasion resisting properties.

When it is desired, however, to increase the abrasion resistance, the strength, or to improve the impact properties, heat treatment is employed.

TORCH CUTTING:

Thicknesses up to 1⁄2" may be torch cut without preheating when the material is to be used as a liner, wear plate or similar applications where no additional fabrication is required.

For heavier material and all thicknesses where subsequent processing by welding or fabricating is involved or where the steel is to be used as a structural member, preheating to 260°C (500°F) is recommended.

WELDING:

Because of the relatively high hardenability of A.R. Steel preheating and maintaining this interpass temperature is required on all thicknesses. Low hydrogen rods of the E90XX or E100XX series are recommended.

FORMING AND BENDING:

A.R. Steel can be readily hot formed and can be cold formed if proper precautions are taken. For intricate forming and for all material over 1⁄2", hot fabrication is recommended at temperatures not less than 815°C(1500°F). A reduction of hardness may occur.
