Why the nitrided ferrochrome and low carbon ferrochrome look different

Brief Introduction to Ferro Chrome

Ferro chrome (FeCr) is a ferroalloy which includes iron and chromium. Depending on the application, ferrochrome contains between 50 and 70% chromium. It comes from the reduction of chromite, a mineral composed mainly of chrome oxide and iron oxide and mined as chrome ore. Ferrochrome is the most important intermediate raw material for the production of stainless steel and uses the majority of the world's chrome supply.

Benefits of Ferro Chrome

Improve Antioxidant Properties

Adding ferro chrome during the steel making process can effectively increase the antioxidant capacity of steel. The chromium element in ferrochrome can effectively protect steel and slow down its oxidation rate to increase the oxidation resistance of steel. This helps increase the service life of the steel.

Improve Corrosion Resistance

In the steel making process, adding a certain amount of ferro chrome according to the proportion of the element content in the molten steel can effectively improve the corrosion resistance of the steel. The chromium element in ferro chrome can effectively adhere to the surface of steel and provide a protective layer to resist corrosion.

Improve Hardness and Wear Resistance

Ferro chrome is now commonly added to the steel making process, mainly because ferro chrome can effectively improve the hardness and wear resistance of steel. In addition, ferro chrome can also purify impurities in steel and improve the hardness of steel.

Types of Ferro Chrome

There are three main types of ferro chrome:

1. Low Carbon Ferrochrome
Low carbon ferrochrome (LC FeCr), with a carbon content of less than 0.5%, is an iron alloy used to regulate the proportion of chromium in steel production without adding carbon and other unwanted ingredients. It is also used by the high temperature alloy industry. The most commonly used process for manufacturing low carbon ferrochrome is metal thermal reduction, known as the two-phase (Perrin) or single-phase process. To obtain the required low carbon content in LC FeCr, carbothermal processes cannot be used.

2. Medium Carbon Ferrochrome
Medium carbon ferrochrome (MC FeCr) has a carbon content between 0.5-4% and is used in the foundry industry and in steel mills with limited refining capacity but requiring low silicon content. MC FeCr can be produced by silothermal reduction of chromite ores and concentrates or by decarburization of HC FeCr in an oxygen-blown converter. The silothermal method is more economical and therefore more important for today's production of medium carbon ferrochromium. This may be due to the lower demand for MC FeCr compared to the higher demand for HC FeCr. LC FeCr can be produced by the same process.

3. Charge Chrome and High Carbon Ferrochrome
The carbon content of charge chromium and high-carbon ferrochrome (HC FeCr) both ranges from 4% to 9%, with the main difference between the two being the chromium and silicon content. Chromium charge typically contains 45-56% chromium and 3-7% silicon, while high carbon ferrochrome typically contains 60-70% chromium and 1-3% silicon. HC FeCr can be produced by the blast furnace method, electric furnace method, or plasma furnace method. The most common modern production method of high-carbon ferrochrome is smelting in submersible arc furnaces. The basic principle of electric furnace smelting HC FeCr is to use carbon to reduce chromium and iron oxides.

Role of High Carbon Ferro Chrome in Stainless Steel Production

High Carbon Ferro Chrome plays a vital role in the production of stainless steel, contributing to the essential properties and characteristics of alloy. Here are its main roles:

Enhancing Corrosion Resistance

Adding high carbon ferrochrome to stainless steel helps form a thin protective layer of chromium oxide on the surface. This oxide layer, also known as the "passivation layer," acts as a barrier to prevent the underlying steel from reacting with the environment, such as air, moisture, and various corrosive substances.

Increasing Strength and Hardness

High carbon ferrochrome adds hardness and strength to stainless steel. The carbon content in the alloy helps increase the overall hardness of the steel, making it suitable for applications requiring durability and wear resistance.

Improving Heat Resistance

High-carbon ferrochrome also enhances stainless steel's ability to withstand high temperatures. This makes it ideal for applications in high temperature environments such as exhaust systems, industrial ovens and jet engines.

Promoting Machinability

The presence of high carbon ferrochrome in stainless steel can improve its machinability, making it easier to shape and form the desired product.

Affecting Magnetic Properties

Depending on the specific composition of the stainless steel alloy, the addition of high carbon ferrochrome can affect its magnetic properties. Some stainless steel grades may exhibit magnetic properties, while other grades may be non-magnetic.

Variety of Stainless Steel Grades

Different grades of stainless steel are produced by varying the percentages of high carbon ferrochrome and other elements in the alloy.

Cost-Effectiveness

High carbon ferrochrome is a cost-effective way to introduce chromium into stainless steel production. Chrome is a key alloying element that determines the corrosion resistance of stainless steel, and high-carbon ferrochrome provides a cost-effective source of this important ingredient.

Safety Tips for Dealing with Ferro Chrome

Care should be taken when handling this Ferro Chrome to prevent eye contact with this material or accidental inhalation or ingestion. Under certain conditions, this material can also catch fire. Therefore, adequate protective measures need to be taken to avoid such accidents. The dangers this alloy may pose and the protective measures that need to be taken are discussed in detail below.

Personal Protection

Exposure to ferrochrome can cause certain health problems, such as skin irritation, causing swelling and redness of the eyes, causing coughing and respiratory irritation. Therefore, adequate protective measures such as filtering respirators, OSHA-approved safety goggles or safety glasses, protective gloves, and protective clothing are required when handling this material in industrial settings. Smoking, drinking, or eating near storage facilities is strictly prohibited as this may result in fire or accidental ingestion.

Accidental Leakage Measures

Chemical spills should be cleaned up immediately and spills should be stored in suitable containers. It's best to moisten spills as this will prevent dust from rising. The scattering and spread of Ferro Chrome alloy dust should be avoided. Storage sections need to be equipped with appropriate ventilation equipment.

Fire Hazard

Ferrochrome dust particles can explode and burn. Therefore, it is recommended not to have any open flames near ferrochrome powder. It is also necessary to prevent the spread of dust. Fireproof electrical equipment is required when handling this chemical.

Storage and Packaging

The chemical can be stored in the following containment systems: Octo-Box containers, Steel or fiber drums, Multiple paper bags, Bulk bags, Pails.
