10KH14AG15 steel is used: for the manufacture of non magnetic parts that work in slightly aggressive environments; household articles and parts of washing machines; the various parts and structures, welded by spot welding; the various parts of aviation.

Note

Steel corrosion resistant austenitic class.
Substitute cold-rolled steel grades 12H18N9 and 17H18N9 for strong and light structures connected by spot welding.

Weldability	without restrictions. It is recommended that RDS standard electrodes. Well welded in shielding gas without the additive and with the additive wire, the basic structure or composition of the type Х18Н9. Not allowed contact welding with low alloy or carbon steel due to the formation of brittle structures in the core of the point. Additional treatment of welded joints is not required.
The temperature of forging	Start - 1160 °C, the end - 850 °C.
