Sandvik high chrome composite hammer

The wear industry, currently used on the domestic market hammer crusher, crusher liner wear-resistant material mainly is high manganese steel, low alloy wear-resistant steel and high chromium cast iron.

Thesewear-resistant materials hammer each have their own characteristics: the characteristics of high manganese steel toughness, easy to hardening, the formation of austenite at high stress and strong impact, abrasion resistance is greatly enhanced. But each enterprise working conditions are not the same, while the required temperature, humidity, corrosion and stress can play up to standard condition normal wear.

Low-alloy steel has a certain hardness and overall performance are generally lower than 55HRC hardness higher than this value, if in the course of its fragility is very easy to break, for the more severe operating conditions and can not meet the need.

Hardness high chrome alloy material is very good, dedicated Industries through advanced heat treatment process so that the hardness can reach HRC62-65. Impact toughness (AK) 30J / C㎡ above have high abrasion effect. But the impact toughness of high chromium alloy material difference in the impact of a large fracture phenomena happens, so high-chromium alloy is mainly used for the production of composite hammer hammer parts.

Our main push high-chromium alloy hammer is a double metal hammer, using a dual-metal thermal compound technology, bi-metal hammer effectively solve the contradiction between hardness and toughness, so that it can adapt to a variety of complex and harsh working conditions.
