Especially, the main characteristics of the three national standard specification are introduced for Austenitic manganese steel castings, cast grinding balls and abrasion resistant white iron castings.

Effect of chromium alloying and complex modification on structures and properties of white cast iron;

An approach to improving anti-wear property of white cast iron;

The microstructure and mechanical properties of a new type wear-resistant white cast iron with the boride as wear-resistant phase were investigated.

Structure and corrosion behavior of the high silicon cast iron in several different environments have been tested by means of weight-loss analysis and metallograph,and compare the corrosion resistant of high silicon cast iron with common gray iron and white iron.

According to their matrix structure, the white irons are divided into ferrite white iron, ferrite-austenite white iron, austenite white iron, pearlite white iron and martensite white iron.

By adjusting composition and adopting step quenching process,the hardenability of the medium chromium white iron was improved,its wear resistance is equivalent to that of the Ni-hard IV,and higher than Ni-hard I by20%～30%.

A review and analysis on the casting market of China, a analysis and compare on some guide lines among the China and some countries of casting production, and a prospect and forecast for develop space of the casting market and the casting export of China in the future have been made,In the paper based on the research task and synthetic data.
