Types of alloy bars can be classified based on alloy percentage and alloy type.

• Chrome alloy steel

• Vanadium alloy steel

• Tungsten alloy steel

• Manganese alloy steel

• Cobalt alloy steel

• Nickel alloy steel

• Molybdenum alloy steel

__________________________

Chrome alloy steel

To make this type of alloy rebar, a high percentage of chromium is poured into molten iron. One of the properties of chromium alloy is its rust resistance. The higher the percentage of chromium in the structure of the rebar, the more resistant it will be to rust. Chrome-plated alloy bars are used in many different industries, due to their rust-proof properties, these types of bars have gained a lot of sales. M040, 70CR2 and CK45 are among the chrome bars. These types of rebars are used in sensitive industrial projects that require the durability and strength of the rebar as well as high tensile strength.

Vanadium alloy steel

In some alloy bars, 0.15 to 0.2% vanadium is used. Vanadium is an element that prevents the enlargement of steel grains and creates a fine-grained texture that has a very good formability. Also, its high percentage in the rebar structure will cause unparalleled resistance and strength.

Tungsten alloy steel

Tungsten has the ability to increase hardness and resistance in rebar. Magnets that never lose their magnetism are made of tungsten steel. Among the other products in which this rod is used, we can refer to the blade, sharpening pen, drill, etc.

Manganese alloy steel

Manganese prevents the formation of austenite particles in alloy rebar and increases its ductility. Sometimes they use a kind of heat treatment called quenching to increase the hardness and strength of steel. The addition of manganese eliminates the mandatory quenching period and strengthens the alloy bar.

Cobalt alloy steel

Cobalt element in alloy bars does not change its hardness at very high and critical temperatures. In order to increase the hardness and resistance of the cobalt bar, some tungsten is added to it.

Nickel alloy steel

Nickel increases the strength and ductility of the rebar. Also, prevention of rust and corrosion of rods is one of the properties of nickel rods. Due to its elasticity and the ability to be wired in addition to its high hardness, nickel bars are the most widely used products among industries.

Molybdenum alloy steel

By adding 0.2 to 0.5% of molybdenum in alloy bars, the resistance to corrosion, the increase in tensile force and the toughness of the bar are multiplied.
