UNS S43036 430Ti Stainless Steel

UNS S43036 "430Ti" material is essentially equivalent to type 439 (UNS S43035) material. It is used for heat exchanger tube, etc. ["430Ti" may also refer to UNS K91800, ASTM F256, a controlled expansion alloy for glass-to-metal sealing. Allegheny Ludlum no longer produces the K91800 material.]
GENERAL PROPERTIES
Allegheny Ludlum Stainless steel Type 439, a titanium
stabilized, 18 percent chromium alloy, also known as
ASTM XM-8 and by the UNS designation S43035, is a
ferritic Stainless steel designed to resist corrosion in a
variety of oxidizing environments from fresh water to
boiling acids.  It may be used in either the annealed,
cold formed or as-welded condition in many applications
where other Stainless steel alloys such as Type 304,
Type 410, Type 409 and Type 430 are used.  Type 439
may also be used in many oxidizing environments
where Type 304 is considered adequate in terms of
general corrosion resistance but is subject to chloride
stress corrosion cracking.
The composition of Type 439 Stainless steel has been
balanced to provide a completely ferritic structure at all
temperatures, to avoid the loss of ductility after welding
and to provide resistance to intergranular corrosion.
Similar ferritic Stainless steels such as Type 430 and
Type 434 are susceptible to brittle martensite formation
after welding and to intergranular corrosion sensitivity in
the as-welded condition.  Type 439 does not require
annealing after welding to restore ductility or to provide
intergranular corrosion resistance.
Excellent resistance to stress corrosion cracking, good
weldability, high thermal conductivity and low thermal
expansion characteristics make Type 439 stainless
steel an ideal consideration for many applications.  For
shell and tube heat exchangers where carbon steel
shells are used with Type 439 tubes, the close match of
thermal expansion coefficients may possibly eliminate
the need for an expansion joint in the heat exchanger.
Type 439 has a low cobalt content, compared to Type
304, making it an attractive consideration for nuclear
applications.
When aplication temperatures are too high for Type 409,
Type 439 provides good oxidation and corrosion resis-
tance for many automotive exhaust system compo-
nents and residential furnace primary heat exchangers.
Allegheny Ludlum currently supplies only an improved
formability version of this alloy, known as AL 439HPTM.
This is especially beneficial for the severe tube bending
required for automotive exhaust manifolds.
STRUCTURE
Type 439 Stainless steel has a ferritic, body-centered
cubic crystal structure at all temperatures below the
melting point.  Angular titanium carbonitride particles
occur randomly in the ferritic matrix.
Specifications
Type 439 Stainless steel (as XM-8 or UNS S43035) is
listed in a number of codes and specifications.  Among
these are:
Pipe and
Tubing
Flat Rolled
Products
Bar Products
ASTM-A268 ASTM-A240 ASTM-A479
ASME-SA268 ASME-SA240 ASME-SA479
ASTM-A803
ASME Boiler & Pressure Vessel Code
Section VIII Division I
Unfired Pressure Vessels
Welded Type 439 tubing is assigned the same allow-
able stresses as welded Type 430 tubing in ASME
Section 8, Division 1, Table UHA 23.  Similarly, allow-
able stresses are the same for both alloys in the bar
and seamless tube product forms.
Availability
AL 439 HP™ Stainless steel is available as sheet and
strip coil in the annealed condition with widths to 48"
and thicknesses to 0.125".  Tube or pipe products using
AL 439 HP™ steel are available from tube/pipe manu-
facturers.
