Metso Crusher steel hammer

Metso Crusher steel hammer in the working conditions of moderate impact, excellent wear resistance, widely used in cement, chemicals, building materials and other industries.

Metso crusher hammer steel, alloy steel as a wear-resistant material to be applied, to play a special and practical effect. Because of the good overall performance alloy steel, with other materials do not have the advantage. As the most widely used traditional materials of high manganese steel materials that are subjected to high impact, will be formed on the surface hardening layer after layer of hardening wear, we will continue to form a new hardening layer. But in the low-stress working conditions, work hardening performance can not play, wear resistance is insufficient to meet production needs. For high chromium cast iron, he said high hardness, is considered the most wear-resistant material, but due to the low yield strength, easy to break. Although not as good as alloy steel toughness of high manganese steel, high chromium cast iron hardness is better, but at a moderate impact, resistant to abrasive wear of the effect is obvious.

Chang Lei company used steel as the material, and through advanced heat treatment process to give Metso Crusher alloy steel hammer. Its temperature is tempered martensite, the tempered martensite with good toughness; the same time, it contains more alloying elements chromium, molybdenum, vanadium, nitrogen, etc., it has a good wear resistance; in non strong impact working conditions, its life compared with traditional high manganese steel has been effectively improved.

Alloy development has a hundred years of history, began extensive use of alloy steels used in about half of the 19th century industry. At that time, production and use of increasing amounts of steel, machinery manufacturing and processing need to solve the problem of cutting steel, in 1868 invented the British Maxi Te component 2.5% Mn-7% W from hard steel. With the development of business and transport, in 1870 with a chrome steel (1.5 ~ 2.0% Cr) built on the Mississippi River bridge span of 158.5 meters in the United States; the processing means difficulties, some industrial countries use nickel steel (3.5% Ni ) construction of large-span bridges. Alloy With economic progress and science and technology continues to evolve, applications are expanding stretch, widely used in construction, chemical, military, cement and other industries.
