Wear resistance can be achieved in cast iron in two basic ways. Firstly a normal grey iron can have small additions of copper, molybdenum, vanadium or chrome added. These are usually up to 1% and can increase the hardness from a base of about 150 Brinell up to 200 to 300 Brinell by promoting the formation of pearlite in the casting, particularly if the carbon and silicon levels are controlled to the lower end of the desired range. If these hardness’s are sufficient, this method has the advantage that the resultant alloy is still machinable.
The second method involves the use of chrome and nickel in much higher quantities, the chrome content being as high as 28% to create a structure that includes a high proportion of primary carbides. Although a lot of chrome iron castings are supplied in the as cast state, these alloys are heat treatable, which promotes the growth of secondary carbides, and can attain hardness’s as high as 700 Brinell.
Tempering can be used to increase the toughness. This second method is, unfortunately, only machinable using special techniques and cutting processes which usually results in castings that are cast to size. Where fixings are required it is possible to cast in threaded bars or blocks of steel that can be drilled and tapped after the casting is made to give fixing and location points.

|Many iron castings can be used without heat treatment (as-cast) but, when needed, can be heat treated to enhance overall properties or localised properties such as surface hardness|
|The chemical analysis of cast iron castings can also be modified to provide improved special properties such as corrosion resistance, oxidation resistance, wear or abrasion resistance|

"High quality and excellent customer service first, realistic development, striving for excellence" has always been the business philosophy of Wuxi Yongjie Machinery Casting Co., Ltd. (Yongjie).
Founded in 1998, premises now cover an area of 26,000 square meters with a production area of 20,000 square meters, with ample room for expansion of production facilities.
The company has developed a strong technical force, with an existing team of fifteen professional casting engineers and technical management (10 personnel achieving high levels of college education).
Yongjie specializes in producing wear-resistant casting. The company's main products are: precision casting of various types of valves, pumps, impeller and construction machinery parts. All types of EPC liner, mixing blades, grate, plate and other wear-resistant, heat-resistant castings. The high product quality, reliability of materials and stable performance are praised by many national and international customers.
The company in 2011 passed the ISO9001: 2008 quality system certification.
To meet the needs of additional overseas customers the company increased the original production line casting in 2009. A further successful EPC production line was also commenced at the end of 2010 which has resulted in an annual output of 10,000 tons of production capacity.
Our production facility is equipped with advanced production testing equipment and an automatic casting machine imported from Japan that has reduced the labor intensity for workers. A direct reading spectrometer to ensure the quality of the products imported from Germany ensures the quality of the products meets requirements.
These improvements in our capacity has enabled us to provide high quality service to customers in China, Spain, Australia, Russia, Kazakhstan, Vietnam, Indonesia, Pakistan, Mongolia, Kyrgyzstan, Tajikistan and so on.
Yonjie’s ongoing objectives are to strengthen management, provide a safe working place for employees and provide staff training and development. We appreciate that these are prerequisites to focus our efforts to cast first-class products, and jointly create the Yongjie brand!
