AISI 310
Austenitic and heat resistant stainless steel delivered in the solution annealed condition.
Similar to AISI 314 / 1.4841, but with higher ductility. Good creep rupture strength which is controlled by the carbon content. Very good resistance to high-temperature corrosion.
The grade can be easily welded. It is used for high temperature applications, up to 1100°C, in oxidating atmospheres. The grade can also be used with a slightly oxidating atmosphere in conjunction with other demanding conditions, such as nitriding, cementation and sulphur containing industries. In these demanding environments it is used with a temperature reduction. Sulphur contents higher than 2g/m3 decrease the maximum temperature to 950°C.
310S can be used at cryogenic temperatures. The grade has excellent toughness and low magnetic permeability.
It has good machining characteristics and is readily fabricated.
