Stamps and purpose of special steels

Are you interested in the brands and purpose of special steels containing nickel from the supplier company AvecGlob? Here you will find interesting information on this topic /

Changes in the chemical composition

Nickel-containing steels are used for the manufacture of various products, from gears to fasteners. In the composition of steels containing nickel, its presence in the chemical composition is not less than 3.5%. The addition of nickel to structural steel leads to an increase in strength without proportionality of a large decrease in ductility.

When nickel is added to the steel as a dopant, the viscosity of the steel increases. At the same time, the strength indicators are increasing, which is used to manufacture products that operate under alternating and shock loads. The addition of nickel in steel reduces the distortion of the shape of the product after heat treatment.

Properties

The critical temperature of steel decreases when nickel is added to it. Because of the lowering of the critical temperature, steel becomes better for any type of heat treatment.

The strength of steel is increased due to alloying of nickel in steel. Strength is the ability of a material to withstand the effects of external forces without destroying or deforming. Consequently, nickel-containing steels are characterized by increased strength.

Supplier — AvekGlob company — offers at a reasonable price from the manufacturer a wide range of special steels containing nickel. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Operational characteristics

Special steels containing nickel can not form carbides. This is a structural disadvantage of such steels, which is especially important for heat treatment in open furnaces when part of the carbon burns out. Therefore, heat treatment of nickel-containing special steels is not performed in reducing atmospheres.

The use of nickel increases corrosion in steel, so in a pure form such steels are not used — additives are used such elements as chromium, molybdenum, vanadium, tungsten, titanium, etc. The abrasion resistance of steel is increased when nickel is added to it in the form of an alloy. Nickel also increases the elastic limit of steel.

Use of special steels containing nickel

The steels in question are used for:

the manufacture of containers for the storage of liquefied gases and for other applications with a low temperature;

production of massive forgings, blades of turbines, screws with high permissible stresses, bolts and nuts;

manufacture of shafts, gears, cardan gears, as well as various machine-building tools.

Supplier — AvekGlob Company — offers to purchase various brands of special steels that contain an increased percentage of nickel. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
