1. A study was made of the following methods of milling of ferrochromium: in a vibratory ball mill under alcohol and acetone and in a planetary mill. The most effective was milling for 30 min in the planetary mill, which comminuted 90% of ferrochromium to a particle size of less that 200. 2. The optimum conditions for the production of TiC-Kh12M-steel materials (50, 40, 35, and 30% TiC) with chromium added to the steel in the form of ferrochromium powder were found to be a pressing pressure of 3 tons/cm2, a vacuum sintering temperature of 1430-1470C, and a sintering time of 1 h. The optimum conditions for the heat treatment (annealing, quenching, and tempering) of these materials were determined. 3. Some of the key properties of the materials were investigated. It was established that the properties of TiC -Kh12M-steel materials alloyed with chromium in the form of ferrochromium are virtually identical with those of the same materials containing additions of pure chromium powder. Ferrochromium, however, being cheaper and more readily available than chromium powder, should be used as a starting material in the manufacture of titanium-carbide-steel alloys.
What else can I help you with?
Is chromium added to steel to make stainless steel?
Yes, chromium is added to steel to make stainless steel. The addition of chromium helps to improve the steel's corrosion resistance and gives it a shiny, reflective surface. Typically, stainless steel contains at least 10.5% chromium.
What is the composition of stainless steel?
material ss 306 grade is there or not
What is the main component of stainless steel?
In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of to the steel 12% chromium that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film.
Which metal requires chromium for its production?
Stainless steel requires chromium for its production. Chromium increases the corrosion resistance of stainless steel by forming a protective oxide layer on its surface.
How is chromium important to ordinary steel?
Chromium is added to ordinary steel to improve its corrosion resistance, hardness, and strength. The formation of a thin oxide layer on the surface of steel, due to the presence of chromium, helps to protect it from rust and other forms of corrosion. This makes chromium an important alloying element in stainless steel production.
Is chromium added to steel to make stainless steel?
Yes, chromium is added to steel to make stainless steel. The addition of chromium helps to improve the steel's corrosion resistance and gives it a shiny, reflective surface. Typically, stainless steel contains at least 10.5% chromium.
It takes 11 times as much selenium to add to a certain batch of steel as it does Chromium If there are 108 pounds of selenium and Chromium together in a batch of this steel how many pounds of Seleni?
98.1828 pounds of addition should be selenium.
What is the composition of stainless steel?
material ss 306 grade is there or not
Why is stainless steel more resistant to a chemical charge then regular steel?
The addition of small amounts of certain elements to the alloy, in particular the metal chromium.
What is the main component of stainless steel?

What metal is added to stop stainless steel rusting?
The most rust resistant stainless steels contain nickel and chromium in addition to iron.

How do you make chrome steel?
Chrome steel is made by combining iron, chromium, and carbon in specific proportions. The mixture is melted together in a furnace and then cast into desired shapes. The addition of chromium increases the steel's hardness, resistance to corrosion, and ability to maintain sharp edges, making it suitable for use in tools, bearings, and other industrial applications.
What element can convert steel into stainless steel?
chromium
What does chromium look like at room temperature?
The appearance of chromium is as a steel.
How does steel become stainless steel?
Oversimplifying it significantly, surface alloying with chromium. Some grades only have the chromium in the surface, other grades the chromium is throughout the material.
