Annealing, quenching and heat treatment of bearing steel

Are you interested in annealing, quenching and other types of heat treatment of bearing steels from the supplier company AvecGlob? Here you will find interesting information on this topic.

Thermal treatment of bearing steels typically involves heating, keeping heat, and cooling at different rates and intensities. All these processes are related to each other and can not be interrupted.

Heating methods for quenching

For the heating of bearing steels, flaming and electric heating furnaces are used. When the rolling bearing steel is heated, intensive carbon burning takes place, which is unacceptable from the point of view of maintaining the required level of bearing performance. Thus, the rolling-bearing steel must normally be in a controlled or protective atmosphere, and for heating decarburization, heating technologies in salt melts or vacuum heating can be used.

The heating temperature is one of the important parameters of the heat treatment process. The heating temperature, during annealing, quenching and other types of heat treatment, varies, but usually the steel is heated to a temperature above the phase transition in order to obtain the necessary structure, which is then kept for a certain time at a given temperature.

When using high-energy heating and surface heat treatment, rapid heating is accompanied by a lack of holding time, while the cooling process is conducted at a controlled rate.

Supplier — AvekGlob company — offers at a reasonable price from the manufacturer a diverse range of bearing steels that meet the technical requirements of the relevant domestic and foreign standards. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Annealing

The total annealing provides for slow cooling, but for normalization — the process of equalizing the hardness along the cross section of the finished product — the cooling rate is increased. To different brands of bearing steel, different requirements for hardness are applied, which determines the normalization regime.

Other types of heat treatment

The process of heat treatment of bearing steel can be divided into general heat treatment, surface heat treatment, local heat treatment and chemical-thermal treatment. Depending on the heating medium, heating temperature and cooling methods, each category can be divided into several different heat treatment processes.

Supplier — AvekGlob Company — offers to purchase various grades of bearing steels that comply with the technical standards and requirements of GOST, DIN EN or ASTM. 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.
