Low Chrome Grinding Forging

production Description

 

Low chromium grinding forging is a kind of wear-resistant material, ‌ is mainly used in cement grinding silo, ‌ metallurgical mine second stage grinding and other occasions. ‌ It is made by forging process, ‌ inherits the cost advantage of low chromium alloy, ‌ and by forging process to further enhance its durability, ‌ especially suitable for the need to withstand greater impact and wear working environment. ‌ In the production process, ‌ the high quality raw materials and advanced technology are used, ‌ to ensure the quality of the products, ‌ not only sold all over the country, ‌ and some exports.

Our advantage

 

The advantages of low chromium forging are mainly reflected in wear resistance, ‌ impact resistance, ‌ cost effectiveness and application range. ‌

Wear resistance and impact resistance: ‌ low chromium wear forging shows good performance in wear resistance and impact resistance, ‌ although in the comparison of low and medium chromium steel forging and casting steel forging, ‌ low and medium chromium steel forging is slightly better in wear resistance and impact resistance, ‌ but low chromium wear forging still has higher hardness and strength, ‌ can withstand medium degree of wear and impact.

Cost benefit: ‌ compared with high chromium steel, ‌ low chromium steel is cheaper, ‌, which makes low chromium grinding in some wear resistance requirements are not particularly high occasions have been widely used. ‌ The low cost not only reduces the initial investment, ‌ but also reduces the frequency of maintenance and replacement over the long term, ‌ thereby further reducing operating costs.

Application: ‌ low chromium grinding is suitable for some wear resistance and impact resistance, ‌ but do not need very high wear resistance of the working environment, ‌ such as general grinding, ‌ cement, ‌ electric power and other industries of ball mill manufacturing, ‌ and tractor track, ‌ cement mill liner, etc.

To sum up, ‌ low chromium grind forging is the preferred material in many industrial applications because of its good wear resistance, ‌ impact resistance, ‌ cost effectiveness and wide application range.
