AMPCO® 8 Rolled sheet and plate



AMPCO® 8 is a single phase alloy (100 % alpha) which possesses high tensile and good yield strength and has good properties at high temperatures (260°C) and sub-zero temperatures. AMPCO® 8 is ductile, easily sheared, bent or deep drawn on standard equipment. It has a high impact and fatigue strength. AMPCO® 8 is a fair hot working material which responds favourably to cold working, the only way of increasing its hardness. Correct annealing will remove any cold worked conditions.

Technological properties

Application areas

AMPCO® 8 sheet and plate has excellent corrosion resistance, not only in alkaline or reducing environments but also in oxydising media. This alloy is ideally suited for applications in the chemical and marine industry. Its inherent wear resistance properties make it well adopted for wear strips and wear plates. Other uses, where both corrosion and wear are factors include chutes, troughs and wear plates in contact with both dry and wet abrasive cereals and crystalline chemicals, etc.
