The test report is delivered on time and with good quality、 and you can enjoy the report delivery service. On the Baijian platform、 customers can complete the inspection process online from ordering services、 submitting commission information、 and finally paying the inspection fee、 without leaving the house. Next、 I will briefly introduce the testing standards and process of Baijia.net for vanadium iron material testing
Vanadium iron is an iron alloy obtained by reducing vanadium pentoxide with carbon in an electric furnace、 or by reducing vanadium pentoxide with electric furnace silicothermic method.
. Widely used as an additive for smelting vanadium containing alloy steel and alloy cast iron、 as well as for manufacturing permanent magnets. The vanadium iron produced in China includes varieties such as V401 and V402、 which contain about 40% vanadium
Mainly used for smelting alloy steel. Approximately 90% of the vanadium consumed in the world is used in the steel industry. Vanadium in ordinary low alloy steel mainly refines the grain size、 increases the strength of the steel、 and suppresses its aging effect; In alloy structural steel、 grain refinement increases the strength and toughness of the steel; Used in conjunction with chromium or manganese in spring steel to increase the elastic limit of the steel and improve its quality; In tool steel、 the main goal is to refine the structure and grain size of the steel、 increase its tempering stability、 enhance its secondary hardening effect、 improve its wear resistance、 and extend the service life of the tool; Vanadium also plays a beneficial role in heat-resistant and hydrogen resistant steels; The addition of vanadium in cast iron promotes the formation of pearlite due to the formation of carbides、 stabilizes the cementite、 and the shape of graphite particles is fine and uniform、 refining the grain size of the matrix、 thereby improving the hardness、 tensile strength、 and wear resistance of the casting
