Details
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).
