Description

The increase in the Al and Fe content results in a material in which the hard gamma 2 phase (about 400 HB) is present. By proper metallurgical control this hard constituent is uniformly distributed giving this alloy its ability to resist wear.

This material data has been provided by AMPCO METAL.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.

Application areas

AMPCO® 21 is used for guide port bushings and wear strips replacing hardened steel and for some cams when no impact is involved. However, the largest single use is as die rings, inserts, forming rolls, etc. in forming, bending or drawing operations, especially when stainless steel is the material being processed. AMPCO® 21 is also widely used as work support blades for the centerless grinding of steel rods.
