Effect of some impurities on the properties of steel 18Kh2N4VA
- 96 Downloads
Structural steel 18Kh2N4VA is susceptible to temper brittleness to a considerable extent.
The presence of antimony, tin, and arsenic in steel 18Kh2N4VA, separately and together, increases the susceptibility of the steel to embrittlement, while copper has practically no effect.
For steel containing several impurities the total effect is determined by adding the effects of each separately.
In structural steel intended for critical machine parts and subject to heating in the process of operation it is necessary to determine the concentration of harmful impurities, especially antimony and tin.
