PRYOR Low Stress Steel Type .

Steel Type for use in applications which dictate that lower stress levels are introduced into the component being marked. This is usually a requirement for Aerospace, Nuclear, Oil and Gas installations, and some M.O.D. work.

2 Styles of Low-stress engraving available :

  • Ministress - round-faced character which gives a continuous line character when marked.
  • Dotstress - for even greater reduced stress levels, a character with similar nose formation to Ministress but with the added benefit of impressing the character in dot formation.

Pryor Low-Stress Steel Type available in 2 character heights, packs of individual characters, set of 26 characters A-Z, Set of 10 characters 0-9, Set of 100 alpha-numeric and punctuation characters according to the most common use plus spacer pieces for non-marking positions and Hand Holder.

Pryor Low-Stress Steel Type Features :

  • Making a mark with Steel Type Sets saves time - in just one stroke, a series of letters and figures can be indented with uniform legibility.
  • The basis of Low-stress marking type is that the character crown, instead of being sharp-faced, is rounded to give a 'softer' impression into the component. This helps to eliminate any stress concentration at the bottom of the indent.
  • Nickel plated pieces with uniformity of character position and depth from one piece to another allows a quick, straight, consistent quality mark to be made on a range of materials including metal and plastic up to a maximum hardness of 37 Rockwell C
  • The Hand Holder comes complete with Allen key to secure the Steel Type in place. Simply adjust the grub screw for quick inscription change. Steel Type Holders to work with are available to purchase separately, check the Holder Compatability & Capacity Chart in Technical Data for options available.
  • Manufactured under stringent BS EN ISO 9001:2008 quality controls and exacting standards.
