Description

An alloy for the repair of high speed tools and which also provides excellent metal to metal wear resistance

Procus 221 has superb high heat retention qualities so as to provide and maintain an excellent cutting edge during machining operations

• the use of procus 221 can prevent the scrapping of worn or damaged tools

Procus 221 alloy formulation contains special elements which enables deposits to resist wear at high temperatures.

From time to time special cutting tools may be required to ensure the machining of a particular job or work at hand. Because of the high red heat generated during the cutting process, deposits of ordinary high speed steel welding rods may not have the high heat retention qualities to maintain a cutting edge during the machining operation. If a cutting tool was made with a deposit from an ordinary electrode, then this deficiency is likely to lead to an inadequate machining job or downtime because of tool/deposit failure.

The alloy formulation of procus 221 provides a deposit which has a fine grain structure with a high compressive strength. The result is a high speed steel deposit, uniform in hardness, so as to provide maximum serviceability. The high heat retention qualities of the deposits ensure that quality cutting edges can be maintained, even at high red temperatures, when a cutting tool is made using a shock resistant steel for a shank.

As deposits of procus 221 will maintain their hardness at much higher temperatures than ordinary tool steel deposits, higher tool speeds and feeds, with minimum tool sharpening, are also achievable.

Deposits of procus 221 can be used for the repair of punches, milling cutters, boring bars, lathe tools, broaches, shear blades etc. It is also ideally suited for many other types of metal to metal wear applications. Deposits of procus 607 can be used a cushion layer, where applicable, to absorb impact.
