Technological properties

Name The value
Welding defects Welding defects of castings after cutting is usually carried out without heating. Welding defects of manual welding is done with electrodes type e-27Х15Н35В3Г2Б2Т (GOST 10052) brand LPS-7. After welding and repair of defects by welding is recommended the use of heat treatment.
