Metal Letter Stamps

Posted by Matt Martin

Metal letter hand stamps are easy to use and allow users to mark static letter sequences onto a variety of materials with little setup.

Metal Letter Stamps

Ideal for low volume applications, metal letter stamps offer users a couple of options like sharp facelow stress full (round) character, low-stress dot character, reverse, and flat face.

These options allow users to select the style of stamp that best fits their application.

Sharp face - Sharp face characters leave a sunk impression or indent when stamped and are the most popular character style for marking metals.

Low stress - Low stress marks are created using either round characters or dot characters. This style reduces the amount of stress placed on the part during the stamping process which serves to maintain the integrity of the part. There are a number of industries (aerospace, oil and gas, piping) that specify low stress marking for all of their components.

Reverse - Typically used for stamping molds and forging dies, reverse characters read “right” on the blank, while standard characters appear backward.

Flat face - Flat face characters creates a bold impression and is typically used in forging, branding applications, and hot stamping with foil.

For the majority of applications, visibility is an important factor, so metal letter stamps also come in a variety of character sizes, most commonly 3/32”, 1/8”, 5/32", 3/16”, 1/4”, and 3/8.”

The Advantages of Steel

advantages of using steel stampsSteel is the ideal construction material for metal letter stamps because it is highly durable. Stamps, by nature, must withstand repeated striking while creating a clear impression on the material being marked.

Steel holds up to the repeated impact and the pressure of stamping very well and provides users with long service life.

The quality of the mark itself is another advantage of steel stamps. When properly used, metal stamps create very clear, crisp, deep marks. Since the marks are clear and the surface is permanently marked, metal stamps are often used to mark parts in industrial settings.

Steel is also a cost-effective material, allowing users to commission custom stamps in low quantities more economically.
