The working part of the hammer head is made of high-wear-resistant high-chromium cast iron, and the handle is made of high-toughness alloy steel.

Features: High wear resistance

Applicable working conditions: Limestone, cement clinker, iron ore, sandstone, coal gangue, basalt and other hard stone crushing fields.

Crusher Hammers

We use proper alloying and and related technological measures to make High chromium iron hammers’ surface hardness reaches more than 58HRC , during the process of wearing will maintain high hardness and high wear resistance.

Applicable working conditions: Suitable for making wearable spare parts with lower impact load and simpler shape.
