Which is the best stainless steel for intergranular corrosion?
Alloy 347 (S34700) is stabilized stainless steel plate which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). Alloy 347 stainless steel plate is stabilized by the addition of columbium and tantalum.See all results for this questionWhat kind of acid can be used in 347 stainless steel?The alloy can be used in nitric solutions, most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10% diluted solutions at elevated temperatures. Alloy 347 stainless steel plate resists polythionic acid stress corrosion cracking in hydrocarbon service.See all results for this questionWhat are Stainless Steel Surcharges? - Rolled Alloys, Inc.The actual surcharge for a particular alloy/product form/size combination is adjusted based on the percentage of the element the alloy contains, and the anticipated production yield. Remember from above that typically the mill will need to melt at least 15% more weight than will be shipped as finished product.

Surface treatment and maintenance are required to protect iron from its tendency to rust. From the need to prevent this loss to rust came the developments of rust-free steel and stainless steel. To prevent rust, at least 10.5 percent chromium is used to form a fine oxidation (passive) film on the surface of the steel.Stainless Steels Welding Guide - Lincoln ElectricTo achieve this, Type 308 is used for Type 302 and 304 and Type 347 for Type 321. The others should be welded with matching filler. Type 347 can also be welded with Type 308H filler. These filler materials are available as coated electrodes, solid bare wire and cored wire.

Heat Treatment Annealing. Annealing is accomplished by heating in the range of 1800/2050°F (982/1121°C). Typically, the alloy is annealed at the lower end of this range to preserve the fine grain size that is required for medical applications. Hardening. This alloy cannot be hardened by heat treatment. It must be hardened by cold working. WorkabilityStainless Steel Cladding and Weld Overlaysheat treatment, which is usually required to re store the cladding to the solution-annealedcondi tion and to bring the backing material into the correct heat-treatment condition. Table 2 lists typical mill heat treatments. The cladding thickness is normally specified as a percentage of the total thickness of the com posite plate.Stainless Steel AL 17-4 Precipitationrequires a simple heat treatment; a one step process conducted at a temperature in the range 900°F (482°C) to 1150°F (621°C) depending on the combination of strength and toughness desired. A wide range of prop-erties can be produced by this one step heat treatment. Heat treatment in the 900°F (482°C) range produces

The intent is for titanium or columbium carbides to form leaving chromium in solution. However, some chromium can still be precipitated when the alloy is heated in the 700 °F to 1500 °F range. The next level of defense is to thermally stabilize the chemically stabilized alloy.

Long term creep strength is also higher. "H" grades are primarily available in plate and pipe. Applicable grades are most commonly 304H and 316H, but high carbon versions of 309, 310, 321, 347 and 348 are specified in ASTM A240/A240M.
