PRYOR interchangeable steel type dotstress

PRYOR dotstress steel types – Single marking stamp or fount set with or without holder

Steel types of the brand PRYOR – DOT STRESS are high quality marking tools for special applications in the industry. Each steel type is made exactly out of high-quality chrome steel with standardized blank dimensions. To each size, a suitable hand holder is available from stock. All standard stamps are nickel-plated and protected therefore against rust.

In contrast to the standard steel types PRIORITY, dot stress steel types are engraved with a round faced character to reduce the stress levels introduced into the component being marked. The variation “dot stress” introduces even lower stress levels than the steel types “low stress” and enhance fatigue properties. Marking stamps “dot stress” produce a character with similar rounded nose formation to low stress but with the added benefit of impressing the character in a dot formation. Please see the difference on the following illustration.

These marking tools are produced especially for the oil and gas industry as well as in the aircraft industry and for power plants and similar applications.

As a distributor of the company PRYOR we can always deliver all letters, figures, as well as the most important punctuation marks in all available sizes in 3.0 and 5.0 mm from stock. Custom made engraving types with individual logos, letterings or symbols can be supplied after drawing or sample.
