General requirements
The most important operational feature of all boiler steel is the stability of its indicators of heat capacity, thermal conductivity and density in a given temperature range (usually - not less than 350...400 ° C). For example, physical properties of one of the best boiler-type steels in this class - 15KhMF steel - correspond to the standards of the following table:
| Operating temperature, °С | Modulus of elasticity, GPa | Thermal conductivity, deg-1 | Thermal conductivity, W/mK | Density, kg/m3 |
| 20 | 214 | - | - | 7800 |
| 100 | 208 | 0,00112 | 41,58 | |
| 200 | 201 | 0,00117 | 40,3 | |
| 300 | 194 | 0,00125 | 38,6 | |
| 400 | 187 | 0,00130 | 36,9 | |
| 500 | 177 | 0,00135 | 32,7 | |
| 600 | 169 | 0,00137 | 34,0 |
Thus, for boiler steel of this type the acceptable temperature range of application is 20...600°C. Evek GmbH offers to buy boiler steel at an affordable price in a wide range. We provide delivery of products to any point of the continent. The price is optimal.
Technical characteristic
Boiler steel differs from common steel in its increased plasticity characteristics and less tendency to harden after plastic deformation and rolling. This allows without the introduction of intermediate annealing to produce from sheet metal by drawing or bending rather complex parts of steam and hot water boilers. Tightness is also ensured by the absence of cracking during heating as well as after caulking of joints.
Thermophysical features
Given that welding is often used in the assembly of boilers, all grades of boiler steel must have an increased ability to weld. An important feature of boiler steel - the temperature of the beginning of scale formation (it does not matter only for structures that are permanently cooled by water).
Ultrasonic inspection
Given the risks of leaks in boilers and other steam installations, all profiles of boiler plate steel are subjected to ultrasonic inspection of the continuity of the steel sheet. For poor-quality melts may have pores, which are formed when cooling the material that has been hot-rolled.
