Specifications

(Ferro chromium)
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).

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 .
   (5)Perfect the performance and nature of casting iron.
