Weldability Good weldability. Welding methods: RDS and ADS under gas protection. Recommended heating and subsequent heat treatment.
Features of heat treatment Casting of stabilized steel foundry quenched in order to: a) prevent the tendency to intergranular corrosion (products can operate in temperatures up to 350 °C); b) to increase resistance against General corrosion; C) to eliminate the revealed tendency to intergranular corrosion; g) to prevent the tendency to stab corrosion; d) to eliminate residual stress (products simple configuration); e) to increase the plasticity of the material. The quenching products should be carried out on mode: heating to 1050-1100 °C, items material thickness up to 10 mm cooling on air, more than 10 mm in water. The holding time at the heating for hardening to products with a wall thickness up to 10 mm - 30 min, over 10 mm - 20 min + 1 min per 1 mm maximum thickness. For more austenization 12H18N9TL steel quenching should be carried out 1100 °C. When working in environments that cause stress corrosion cracking, castings should be subjected to stabilizing annealing regime: heating up to 870-900 °C, exposure time of 2-3 h, cooling in air.
Defect welding Welding defects of castings after cutting is usually carried out without heating. Welding defects of manual welding is done with electrodes type e-08Х19Н10Г2Б (GOST 10052) brand DH-15. After welding and repair of defects by welding is applied heat treatment.
