More info. The material is used in the pressure section of a solenoid valve. This is a 3-piece assembly which is EB or laser and TIG welded. I realize that free machining grades are not recommended for welding but we have been successfully doing this for better than 10 years and proof...
I'm looking for a ferritic stainless steel for a magnetic application which has better corrosion resistance than 430FR. I ran a salt spray test per RTCA/DO-160D and surface corrosion appeared within 24 hours. This is not acceptable to our customer. Any information would be appreciated.
