The study of metal alloys is a significant part of materials science. Of all the metallic alloys in use today, the alloys of iron (steel, stainless steel, cast iron, tool steel, alloy steels) make up the largest proportion both by quantity and commercial value.

Iron alloyed with various proportions of carbon gives low, mid and high carbon steels. An iron-carbon alloy is only considered steel, if the carbon level is between 0.01% and 2.00%. For the steels, the hardness and tensile strength of the steel is related to the amount of carbon present, with increasing carbon levels also leading to lower ductility and toughness. Heat treatment processes such as quenching and tempering can significantly change these properties, however. Cast Iron is defined as an iron–carbon alloy with more than 2.00%, but less than 6.67% carbon. Stainless steel is defined as a regular steel alloy with greater than 10% by weight alloying content of Chromium. Nickel and Molybdenum are typically also found in stainless steels.


The research on the material and production process of mechanical parts in various fields is the reason why our products remain excellent.

Unfortunately, our research is only used to improve the quality of our products. You can enjoy the service of our products, but we do not disclose the detailed research.

Yes, we will initiate a new research topic if the results of our existing studies also do not meet your needs.

We have complete testing equipment to do the testing

When enough tests have been conducted, we will try to conduct market testing
