This specification has been declared "NONCURRENT" by the Aerospace Materials Division, SAE, as of March, 2008. It is recommended, therefore, that this specification not be specified for new designs. "NONCURRENT" refers to those specifications which have previously been widely used and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs. Similar but not necessarily identical products are covered in AWS A5.9 ER316L. However, it is provided for information only and does not constitute authority to substitute this specification for the "NONCURRENT" specification. This specification covers a corrosion and heat resistant steel in the form of welding wire. This wire has been used typically as bare wire filler metal for gas-tungsten-arc or gas-metal-arc welding of corrosion and heat resistant steels and alloys, but usage is not limited to such applications. The relatively high ferrite content promotes weldability by combatting microfissuring and minimizing cracking in heavy sections but limits use of the wire to applications not operating in the sigma-forming temperature range.
