Description
The use of ferromanganese
1. The use and characteristics of micro-carbon ferromanganese This product is not only suitable for low-carbon alloy structural steel, especially for high-quality steel, and does not need to change the original steelmaking process, can optimize alloys, improve steel The inherent quality of steelmaking alloys reduces the cost of steelmaking alloys, which has obvious economic benefits.
2. Uses of low carbon ferromanganese and medium carbon ferromanganese: This product is the main raw material for the production of stainless steel, high temperature heat-resistant steel, structural steel, tool steel and other special steels and welding electrodes. Low carbon ferromanganese
