Stainless Steel 19-9DL

Soak at 1800-2150 F, air cool. For stress relieving, heat to 1200 F (649 C), hold for 60 minutes and air cool.

Applications include a wide variety of jet engine components including casings, manifolds, buckets and fasteners. Generally employed in applications where resistance to intergranular corrosion is not a great concern.

This alloy can be successfully formed using most common practices. If severe forming is employed the material should be stress relief annealed immediately after forming at 1200-1300 F.

Soak thoroughly at 2150 F prior to working, air cool forgings. Given sufficient hammer strength, this material can be forged down to 1250 F.

This material will not respond to hardening by thermal treatment.

This alloy is austenitic and will not respond to heat treatment.

This material can be successfully forged, headed and upset.

Experienced machinists compare the characteristics of this material to those of 316 stainless. Constant feeds, slow speeds and ample sulphurized lubricants are necessary for optimum results. The material will produce tough, "gummy" chips. The use of chip breakers or curlers will effectively deal with this problem.

This alloy is primarily an austenitic stainless steel which combines fine grain and stability in a wide range of temperatures with good resistance to both corrosion and brittle failure.

This alloy can be successfully welded using all commonly employed techniques. When required, filler metal should be of matching chemistry for optimum performance.
