Alloy 410 HT is the basic, general purpose, heat treated version of Type 410. It is a martensitic type, used for general purpose, where corrosion is not severe. Alloy 410 contains a minimum of 11.5% chromium which is just sufficient enough to demonstrate corrosion resistance properties in mild atmospheres, steam, and many mild chemical environments.

DIN: 2.4660

Corrosion Resistance:

Good corrosion resistance to atmospheric corrosion, potable water, and to mildly corrosive environments
Its exposure to everyday activities (sports, food preparation) is generally satisfactory when proper cleaning is performed after exposure to use
Good corrosion resistance to low concentrations of mild organic and mineral acids

Welding Characteristics

Readily welded by all standard methods
To reduce the risk of cracking, it is suggested to pre-heat the work piece to 350 to 400oF (177 to 204oC)
Post weld annealing is recommended to retain maximum ductility

Heat Treatment

The proper hot work range is 2000 to 2200oF (1093 to 1204oC)
Do not work this material below 1650oF (899oC)
