Punch set PRYOR lowstress – Punch set PRYOR ministress


Marking stamps “low stress” or also called “ministress punches“ are specially engineered so that lower stress levels are introduced into the component being marked. These punches are used especially for the oil, gas and aircraft industry but also for power plants and similar applications. Instead of the sharp faced characters, these punches are manufactured with a radius engraving to reduce the stress levels. Please see the difference on the following illustration.

Our punches are manufactured of high quality Chromium tool steel. All stamps are hardened precisely, giving a hardness of 58-62 R.C. at the character end and 32-40 R.C. at the striking end. Please note, that the hardness of the component should not exceed 40 R.C.

All sets are delivered in a strong plastic box with separate compartments for each stamp to allow rapid selection. The production of the punches is certificated after ISO 9001:2000. For special security requirements there is a special security holder available.
Marking stamps of the series "low stress“ are available as a single punch as well as in sets of A-Z and 0-9 in different sizes. All standard stamps are nickel-plated and protected therefore against rust.
Please, note that the size of the stamps must be measured on top at the sharp faced characters end.
