Penn Stailess now stocks 303 grade stainless steel (UNS S30300) in plate, round bar, square bar, hex bar, and rolled flat bar. Alloy 303 is a non-magnetic, austenitic stainless steel that is not hardenable by heat treatment.
321 stainless is a titanium stabilized grade commonly used for service in the 1000-1600F temperature range. For service temperatures up to about 1600F, a stabilizing treatment at 1550-1650F, air cool, may be used to provide optimum resistance to intergranular corrosion and to polythionic acid stress corrosion cracking.
321 Stainless Steel 321 stainless steel stockholders and suppliers, delivering to the whole of the UK. This grade is a titanium stabilised austenitic stainless. The addition of titanium to 321 stainless helps improve its welding properties and the elevated temperature properties of the steel. This stainless steel offers excellent oxidation
321 Stainless Steel Sheet, Coil, Plate & Bar - AMS 5510, 5645. 321 is a titanium stabilized austenitic chromium-nickel stainless steel which was developed to provide an 18-8 type alloy with improved intergranular-corrosion resistance. This material is stabilized against chromium carbide formation by the addition of titanium.
Pitting/Crevice Corrosion. The resistance of the stabilized Type 321 alloy to pitting and crevice corrosion in the presence of chloride ion is similar to that of Type 304 or Type 304L stainless steels because of similar chromium content.
347 Stainless Steel Sheet, Coil and Bar - AMS 5512, 5646. This material is stabilized against chromium carbide formation by the addition of columbium and tantalum. Since these elements have a stronger affinity for carbon than chromium, columbium-tantalum carbides precipitate within the grains instead of forming at the grain boundaries.
Both AISI 316 stainless steel and AISI 321 stainless steel are iron alloys. They have a very high 96% of their average alloy composition in common. There are 33 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
AISI 321 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 321 is the AISI designation for this material. S32100 is the UNS number. Additionally, the British Standard (BS) designation is 321S12. The properties of AISI 321 stainless steel include two common variations.

Coefficient of Thermal Expansion Data A Coefficient of Thermal Expansion, typically represented by the symbol , is a measure of the change in length of a material in response to a change in its temperature. Within small temperature changes, the change in the length of a material is proportional to its change in temperature.

for the thermal linear expansion and its instantaneous and mean coefficient of seven of the 300 series and two of the 400 series of AISI stainless steela, which were selected primarily because of their current technological and com-
industry. For example, in thermal-cracking stills in the petroleum industry, some plants have standardized on Type 304 stainless steel, whereas, other plants with similar equipment and operating conditions use chromium-molybdenum steels with lower alloy contents. Naturally, the latter materials will not last as long as
Linear thermal expansion coefficient is defined as material's fractional change in length divided by the change in temperature. Coefficient of linear thermal expansion is designated by the symbol (alpha). The SI unit of thermal expansion coefficient is (C)-1 and U.S. customary unit is (F)-1.
reduction of mechanical properties of ferritic stainless steels under fire conditions is largely unknown. In the present work, an experimental research programme was carried out to investigate the mechanical properties of various ferritic stainless steels at temperatures up to 1000C.
The ability of stainless steel to maintain clean surfaces often allows better heat transfer than other metals having higher thermal conductivity. Magnetic Permeability The stabilized Alloys 321 and 347 are generally non-magnetic in the annealed condition with magnetic permeability values typically less than 1.02 at 200H.
321 is similar to 304, but uses titanium as a stabiliser. They differ in that they are resistant to intergranular corrosion after heating to temperatures in the carbide precipitation range. Applications include aircraft exhaust manifolds, furnace parts, heat exchangers, furnace parts etc.
Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 8001500F (427816C).
Stainless steels are used at temperatures up to 1700 F for 304 and 316 and up to 2000 F for the high temperature stainless grade 309(S) and up to 2100 F for 310(S). Stainless steel is used extensively in heat exchangers, super-heaters, boilers, feed water heaters, valves and main steam lines as well as aircraft and aerospace applications.
Alloy 321 is a general purpose austenitic stainless steel with a face centered cubic structure. It is essentially non-magnetic in the annealed condition and can only be hardened by cold working. Titanium is added to supress grain boundary Chromium Carbide precipitation and reduce susceptibilty to intergranular corrosion.
Background. Grade 321 is the grade of choice for applications in the temperature range of up to about 900 C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.

The vast majority of failures reported to Rolled Alloys, involving breaking or deformation in service, are due to restraint of thermal expansion. For successful design and installation of high temperature equipment it is critical to take thermal expansion into account, and to be able to calculate the amount of expansion to be expected.
