Alloy tool steel: Cr06
Standard: GB / T 1299-1985
● Features and application:
Measuring and cutting steel, is a small amount of chromium-containing low-alloy tool steel. The cold-rolled into thin strips generally, the used to make low-load operation, requiring sharp edge of the tool, such as surgical knives, razor blades, etc. Also be used as a scraper, chisel, rasp and wool scissors and other manual and motorized tools.
