1.Chemical composition:Si,Fe,Al,Ca,P,S
2.Type;High,Medium,low,Micro Carbon
3.Brand:FeCr67C6.0,FeCr55C600,etc
4.Size: The quality of each piece should not be more than 15kg and its size
range is less than 20mm×20mm. the amount of debris whose size is less than
20mm×20mm should not exceed 5% of the total quality of this batch of
products.
5.Properties: Chrome is mainly used to improve the antioxidation and
corrosion resistance of steel to make the surface of steel after it is oxidized to
form strong adhension oxide film. Then it stops being oxidized or decelerates
being oxidized. Micro-carbon ferro chrome is applied to making stainless
steel, acid-resistant steel and heat resistant steel.
6.Package:1Metric Ton per big bag (polypropylene knitted bag).
7.Chemical Compositions(GB/T3649-1987)
8.Advantages:
(1)Iimprove the hardness,strength,elasticity and permeability of steel
(2)Lower the hysteresis loss of the transformer.
(3)To prevent the formation of carbides.
(4)Promote the precipitation and nodulization of graphite .
