GOST 7350-77, GOST 5582-84, GOST 4986-78, GOST 5945-75, GOST 18143-72, GOST 9940-81 and GOST 9941-81 steel 12X18H10T and GOST 7350-77, GOST 5945-75, GOST 18143-72 steel 12X18H9T must stand against intergranular corrosion test methods and AM AMU GOST 6032-89 with duration of exposure in the test solution, respectively 24 and 8 hour Tests are provoked by heating at 650°C for 1 h.

In continuous operation became stable against oxidation in air and in the atmosphere of the combustion products at temperatures up to 900°C and when working in conditions of thermal cycles to 800°C.

Steel 12X18H10T and 12X18H9T have sufficiently high heat resistance at 600-800°C.
Technological parameters 12X18H10T

Steel 12X18H10T and 12X18H9T have good workability during hot plastic deformation. However, during hot processing should take into account the specific chemical composition of the melt, having in mind the content of 8-ferrite. Special precautions should be taken during the deformation of cast metal. To avoid uncorrectable defects - flaws recommended ingots of steels 12KH18N10T and 12X18H9T when the content is 20% of 8-ferrite and more to heat no higher than 1240-1250°C, when the content of 16-19 %-not above 1255°C and when the content up to 16% to 1270°C. Temperature range for the pressure treatment of the deformed metal is 1180-850°C. the Rate of heating and cooling is not limited.
In both cold steel allow a high degree of plastic deformation.
To remove stress and improve durability of welded joints in addition to quenching the welded structure is subjected to a stabilizing annealing at 850-900°C.
