After several years of development, Sichuan Liaofu Special Steel Industry Co., Ltd mainly produce die steel, alloy steel,high speed steel and Valve steel.
These highly alloy MN-NI CR MO N magnetic and non mannetic steels are used for inlet and exhaust vavles for IC engines,which function unders
conditions of severe heat and corrosion stress.The steels are known to retain their properies at elevated temperatures.
The material 1.4871 belongs to the material group "Valve Steels". The steel material "1.4871" has three alternative names. We also have the chemical analysis of 1.4871 available for you below.
The material "1.4871" contains Chrome, Manganese, Nickel, Nitrogen, Phosphorus, Silicon and Sulfur
Engine Valve Steel has different standards
Our factory mainly produce below vavle steel grades:
