Silicon manganese is an alloy of Iron, Silicon & Manganese. It has higher Silicon content in comparison to Ferro Manganese. Silicon reduces the solubility of carbon in manganese alloys, so carbon contents are inversely proportional to silicon content. It is a more potent deoxidizer of steel compared to Ferro manganese. Deoxidization with Mnsi results in cleaner steel than using Ferro Silicon. More than half of the Silico Manganese produced globally is produced in China Product: Ferro Silicon-Manganese. Products: Silicon manganese alloy Content: Mn: 60.0- 70.0%, C: 3.50% Max. P: 0.250% Max. S: 0.04% Max, Si: 14-18% Size :5 -- 60mm: 90% min, 60 -- 80mm:max 10%, more than 80 mm: 0% Packing :1 ton bag, supply free sample; 1kg
