Technical characteristics of boiler steel

Boiler steels are designed for the manufacture of critical parts and units of boiler units. Since they function at elevated temperatures, as well as in constant contact with hot water and steam, boiler steels are required:

1. - increased heat resistance and long-term strength (increased creep resistance);
2. - ductility under conditions of prolonged loading, mostly - tensile stress;
3. - resistance to scale formation;
4. - anti-adhesion ability;
5. - resistance to different types of corrosion;
6. - fatigue strength, under repeated - short-term and long-term external loads;
7. - stability of mechanical characteristics at continuous operation temperatures.

Grade selection

Selection of boiler steel grade depends on conditions of its subsequent application. For steam pipeline material the requirements of GOST 8731-88 and GOST 8738-88 are followed, and for steam boiler parts - GOST 5520-92 standards.

Technical characteristics of spring steels

The main operational quality is considered their high elasticity. This parameter increases with increasing carbon percentage, therefore all spring steels contain at least 0.5...0.55% C. Technical requirements for the steels under review are regulated by State Standard GOST 14979-90, and manufactured springs - by GOST 13764-86 standards. Requirements to spring steels are as follows:

1. - high fatigue strength under repeated-transient loads and vibrations;
2. - relaxation resistance;
3. - the ability to quickly restore its original shape after removal of external load;
4. - dimensional stability at elevated temperatures (up to 300°C);
5. - wear resistance.

The spring steels can be alloyed and unalloyed. The former are used in more demanding operating conditions.
