High hardness and uniformity; hardness uniformity; high tensile strength, no shrinkage, cast iron profiles offer, easy to wear, Stomata, slag, trachoma and other defects, superior mechanical properties, which is a significant feature is a c

Ductile iron profiles effectively improve the mechanical properties of cast iron, in particular, improve the plasticity and toughness, resulting in higher strength than carbon steel. Ductile iron profiles are obtained by ballification of gr

Graphite shape The most representative of the graphite shape is spherical. The quality of the nodular cast iron is generally assessed by the rate of spheroidization. Graphite more rounded, small, more uniform distribution of the metal matri

Ductile iron pieces of inspection, including visual inspection, ultrasonic testing and magnetic test. Special inspection should pay attention to the surface pores and the surface of the difference between the trachoma, in general, the inner

According to the use of different purposes, has designed and manufactured a variety of thermometer. The design is based on the results of the use of solid, liquid and gas is affected by temperature and thermal expansion and contraction phen

Automatic drainage valve for compressed air storage tanks or other gas pressure vessels to exclude water or harmful liquids. Automatic drainage valve is mainly made up of valve body, valve cover, valve core, spring, adjusting bolt, drainage hole, through

The formation of chromium, aluminum and silicon elements, at high temperature can promote the formation of a dense metal surface oxide film, to prevent further oxidation, is to improve the oxidation resistance of steel and high temperature gas corrosion o

Alloy steel with high strength and good chemical stability at high temperature. It includes two types of anti oxidation steel (or high temperature resistant steel) and hot steel. Anti oxidation steel generally requires good chemical stability, but the loa

Heat resistant cast iron can be used at high temperature, its anti oxidation or anti growth performance in line with the requirements of the use of cast iron.
