Product Description

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). 7.chemical compositions(gb/t3649-1987) (gb/t5683-1987) type brand chemical compositions(%) cr c si p s scope ? ? ? ? ? ? ? ? = = micro-carbon ferro chromium fecr69c0.03 63~75 0.03 1 0.03 0.25 0.03 0.025 fecr55c3 60 52 1.5 2 0.04 fecr69c0.06 63~75 0.06 1 fecr55c6 60 52 1.5 2 0.04 0.06 0.03 fecr69c0.10 63~75 0.1 1 0.03 0.25 fecr55c10 60 52 1.5 2 0.04 0.06 0.03 fecr69c0.15 63~75 0.15 1 0.03 0.025 fecr55c15 60 52 1.5 2 0.04 0.06 0.03 low-carbon ferro chromium fecr69c0.25 63~75 0.25 1.5 0.03 0.025 fecr55c15 60 52 2 3 0.04 0.06 0.03 0.05 fecr69c0.50 63~75 0.5 1.5 0.03 0.025 fecr55c50 60 52 2 3 0.04 0.06 0.03 0.05 medium-carbon ferro chromium fecr69c1.0 63~75 1 1.5 0.03 0.025 fecr55c100 60 52 2.5 3 0.04 0.06 0.03 0.05 fecr69c2.0 63~75 2 1.5 0.03 0.025 fecr55c200 60 52 2.5 3 0.04 0.06 0.03 0.05 fecr69c4.0 63~75 4 1.5 0.03 0.025 fecr55c400 60 52 2.5 3 0.04 0.06 0.03 0.05 medium-carbon ferro chromium fecr67c6.0 62~72 6 3 0.03 0.04 0.06 fecr55c600 60 52 5 0.04 0.06 fecr67c9.5 62~72 9.5 0.03 fecr55c1000 60 52 10 5 0.04 0.06
