HPA maintains a large stock of material in their warehouse and offers waterjet, band saw cutting, shearing, plasma, and abrasive cutting. This material is offered in plate, bar, sheet, wire, along with fasteners and forgings.

We separate our alloys into 3 categories:

Typically, corrosion is the inital cause of part failure. If corrosion is mitgated, then wear becomes the leading cause of part failure. After severe galling and seizing, the part finally ceases to move, or "freezes up".

Our wear resistant alloys help avoid this outcome.

High temperature resistance is essential in many applications. Gas turbines, fuel nozzles, heat treating fixtures, and furnace muffles are just a few examples. These materials must very high heat resistant properties, an extreme oxidation potential and strong cycling.

Our heat resistant alloys give you the material needed suit your high temperature use case.

Typically, corrosion is the inital cause of part failure. Material corrosion can occur from two primary factors: oxidizing acids and reducing acids. Dealing with both types in the operating environment can be challenging, and it's even worse when operating in high temperatures.

Our corrosion resistant alloys will ensure your production equipment continues to operate despite your acidic environments.
