ferromanganese is combination of manganese oxide and iron oxide
ferromanganese is combination of manganese oxide and iron oxide, which are divided into three groups: high carbon ferromanganese, medium carbon ferromanganese and low carbon ferromanganese. manganese is a hard metal with a silver color. most of extracted manganese from mines is used for metallurgical use and welding in the form of lumps and micronized powder, and the rest is widely used in the chemical, electronic, and industrial varnish industries. due to the fact that the highest consumption of manganese and ferromanganese in the welding industry is granulation in grades with carbon of about 1.5% (medium carbon) and 0.8% (low carbon), khorasan powder metallurgy company routinely produces two grades in granulation suitable for the welding industry and based on the customer's request. also, in the case of customer order, high-carbon ferromanganese is also included in the company's product list.
among the characteristics of this metal, it can be mentioned that if a certain amount of that is added (depending on the type of electrode coating or welding powder and the manufacturer's formulation), risk of breaking can be reduced and strength and resistance can be increased. in general, manganese is one of the five main alloying elements in steels, and increasing it, in addition to increasing the weld resistance to cracking, improves the quality and better deoxygenation of the weld core.
