AISI D2 and JIS SKD11 are the most-quoted cold-work tool steels in industrial blade manufacturing. They share a spec sheet — but the heat treatment, dimensional consistency and field performance are not identical. Here is the engineering comparison.

Crusher blades take the largest impact loads in industrial cutting. A 30 mm M16 nut in a granulator feed will shatter a D2 blade in 200 cycles. This guide covers jaw, hammer, rotary and impact crusher blades for stone, ore, scrap and ASR.
Granulator rotor and bed knives see impact, contamination and abrasive fillers. The right grade, geometry and edge prep separates a 2-week knife from a 6-month one. This guide covers rotor, bed, screen and wear-strip selection for film, rigid, fibre and filled polymer recycling.
