Ferro Chrome

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 .            (5)Perfect the performance and nature of casting iron.          (GB/T5683-1987)TypeBrandChemical Compositions(%)CrCSiPS　ScopeⅠⅡ　ⅠⅡⅠⅡⅠⅡ　≥≤Micro-carbonFeCr69C0.0363~75　　0.031　0.03　0.25　　Ferro chromiumFeCr55C3　60521.520.040.03　　FeCr69C0.0663~75　　0.061　　0.025　　FeCr55C6　60521.520.040.060.03　　FeCr69C0.1063~75　　0.11　0.03　0.25　　FeCr55C10　60521.520.040.060.03　　FeCr69C0.1563~75　　0.151　0.03　0.025　　FeCr55C15　60521.520.040.060.03　Low-carbonFeCr69C0.2563~75　　0.251.5　0.03　0.025　　Ferro chromiumFeCr55C15　6052230.040.060.030.05　　FeCr69C0.5063~75　　0.51.5　0.03　0.025　　　FeCr55C50　6052230.040.060.030.05　Medium-carbon Ferro chromiumFeCr69C1.063~75　　11.5　0.03　0.025　　FeCr55C100　60522.530.040.060.030.05　FeCr69C2.063~75　　21.5　0.03　0.025　　FeCr55C200　60522.530.040.060.030.05　FeCr69C4.063~75　　41.5　0.03　0.025　　FeCr55C400　60522.530.040.060.030.05　Medium-carbon Ferro chromiumFeCr67C6.062~72　　63　0.03　0.040.06　FeCr55C600　605250.040.06　FeCr67C9.562~72　　9.5　0.03　　FeCr55C1000　60521050.040.06
