2. C80 Carbon Steel : it is economical, hardness can reach HB280–360 after quenched and tempered, Suit for pure earthmoving and loose material handling, not fit rocky and high-impact sites.

3. NM400/NM450 alloy steel : own superior anti-scouring and wear resistance compared with boron steel, has greatly extending service life for long-term gravel, aggregate and construction debris working scenarios.

4. Mn13 high manganese steel : own work-hardening property, the surface will get harder under continuous impact. It fits occasional rock and hard impact. Not economical for pure earthmoving.
