Chromium Metal – The most corrosion-resistant high-temperature alloy additive

Chromium metal is the core foundational component of various superalloys. Its outstanding corrosion resistance and high-temperature resistance endow the alloys with stable adaptability under extreme working conditions — even in harsh environments such as high temperature, high pressure, or corrosive media, chromium-containing superalloys can still maintain structural integrity and stable performance. They widely support the reliable operation of key fields including aerospace engines, high-end petrochemical equipment, and core components of precision manufacturing, serving as the core support for material solutions in extreme environments.

Our company

We are deeply involved in the chromium materials industry

We are part of the DELIKE GOURP. The quality of chromium metal is determined by the process as well as the raw material, and we rely on DELIKECHEM advantage of producing chromium oxide green to control the quality of chromium metal from the source in a long chain.

Chromium

is a brittle metal that cannot be used alone as a structural material due to its inherent brittleness. Instead, it is frequently smelted with metals such as iron, cobalt, nickel, tungsten, titanium, aluminum, and copper to form alloys—these specialized engineering alloys inherit chromium’s strengths, boasting excellent heat resistance, high mechanical strength, and superior wear resistance, making them indispensable for demanding industrial applications.

Chromium in the high-temperature alloy matrix a very important role is the formation of Cr2O3-type oxide film, so that high-temperature alloy parts have good oxidation and corrosion resistance. At present we found 15 kinds of deformation of high temperature alloy oxidation weight gain and chromium content of the relationship between the view, although the alloy’s matrix is different, other alloying elements of the difference is also very large, but still can see, chromium on the oxidation resistance of the improvement of the role of obvious, and the higher the content of chromium, the better the antioxidant properties. The same chromium content continues to increase, the maximum corrosion depth of the alloy in the thermal corrosion environment continues to reduce, and the thermal corrosion resistance continues to improve.
