BSI’s guide to understanding ROUND FACED LOW STRESS STAMP & TYPE MARKING
ROUND FACED LOW STRESS HAND STAMPS & STEEL TYPE INTENDED USE:
PRYOR ROUND-FACED Character hand stamps & steel type were specially designed for applications which require that lower stress levels be introduced into the component being marked. This is typically a requirement for the Aerospace, Nuclear, Oil and Gas industries. They are also desirable when marking boilers or pressure vessels. Instead of the character having a sharp, chisel point face found on standard stamps, Round-Faced characters are solid-face rounded characters and impart less stress into the material being marked. There are two styles of Low Stress stamps, Round and Dot faced characters. Round Solid-Face stamps meet ANSI specification IN45, 2.2A39 for low-stress impressions. Dot-Faced stamps produce even lower stress impressions than Round Solid-Face stamps and meet Nuclear American Society of Mechanical Engineers Code Section 3, Div. 1, Paragraph NA-3766.6 (2).
ROUND FACED HAND STAMPS & STEEL TYPE CHARACTERISTICS:
PRYOR Round Faced Character hand stamps are made from high quality Chromium Tool Steel. Round-Faced hand stamps are hardened to between 58 and 62 Rockwell C scale at the character end of the stamp for an extended, extra-long tool life and Round-Faced hand stamps are tempered to between 32 and 40 Rockwell C scale on the striking end of the stamp to offer maximum safety in use. Round Faced steel type is hardened between 58 and 62 Rockwell C scale throughout. Each individual stamp or type piece is nickel plated for rust prevention. The hand stamps character end is tightly beveled which assists the user in visually aligning and positioning the character on the surface of the material being marked. Steel type is precision ground to line up in a type holder which will hold a string of characters.
CHARACTER SIZE AVAILABILITY:
Character size is a measurement of the characters height and several sizes are available. ROUND-FACED hand stamps character sizes include 1/8” (3.0mm), 3/16” (5.0mm) and 1/4” (6.0mm). ROUND-FACED steel type sizes include 1/8” (3.0mm) and 3/16” (5.0mm). Round-Faced hand stamps can be purchased in Letter Sets of 26 pieces, Number Sets of 10 pieces or Combo Sets which include both letters and numbers of 36 pieces. Round-Faced steel type is generally purchased in sets of 100+ pieces including a type holder & case. Individual Round-Faced steel type characters are also available. Please visit the BlueSpotIndustrial.com web store for additional details and availability.
As with all striking tools, we recommend the use of appropriate safety protection. Safety glasses and gloves should be worn at all times.
PRYOR Dot Faced hand stamps and steel type are designed & produced in the UK under stringent BS EN ISO 9001:2008 quality controls and exacting standards.
