Prices for roll forming machine post-shearing blades vary drastically on the market. Grade labeling is frequently misleading. Many budget-tier suppliers label their tools as "SKD11" or "Cr12MoV" but secretly utilize 9CrSi (low-alloy tool steel) to slash manufacturing costs. Understanding the metallurgical differences between these materials explains why cheap blades dull, chip, and fail prematurely.
The Shop-Floor Reality: The nominal steel grade is only a baseline. Steel cleanliness and the heat treatment process dictate the actual service life of a blade. Poor heat treatment can reduce the lifespan of an identical steel grade by 2 to 3 times. Read More
