With the addition of nitrogen as a strengthening agent, the alloy can be dual certified as Alloy 317 (UNS S31700).
Alloy 317L is non-magnetic in the annealed condition.
It cannot be hardened by heat treatment;?however?the material will harden due to cold working.
This grade has surpassed its original intent and overlapped into many industries proving useful owing to its high level of molybdenum amount other elements, which allows 31254 to be used successfully in various applications such as Flue gas desulfurization and Chemical environments.
Stainless steel grade 254 SMO? is a very high end austenitic stainless steel.
It is designed with a combination of impact toughness resistance to chloride stress corrosion cracking, and pitting and crevice corrosion with strength that is twice that of the stainless steel 300 series.
For certain applications, grade 254 SMO has been reported to be a cost-effective substitute for high nickel and titanium alloys.
It is known to possess excellent workability as well.
Alloy 254 SMO is a high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content.
It has high nickel (24%), molybdenum (6.3%), nitrogen and chromium contents that give it excellent resistance to chloride stress corrosion cracking, chloride pitting, and exceptional general corrosion resistance.
AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.
AL6XN has greater tensile strength than common austentitic stainlesses, while retaining high ductility and impact strength.
It was developed for enhanced creep resistance and for higher strength at temperatures above 1000¡ãF (537¡ãC).
Chromium, molybdenum, nickel and nitrogen all contribute to overall resistance to corrosion by various media
In most instances, the carbon content of the plate enables dual certification.
Chromium is the principal agent for conferring corrosion resistance in neutral or oxidizing environments.
Alloy 347 stainless steel plate cannot be hardened by heat treatment, only by cold working.
Chromium, molybdenum and nitrogen increase resistance to pitting corrosion. Nickel imparts the austenitic structure.
It can be easily welded and processed by standard shop fabrication practices.
?The low carbon content of Alloy 317L enables it to be welded without intergranular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition.
Alloy 347 stainless steel plate exhibits good general corrosion resistance that is comparable to 304.
UNS S31254 is often referred to as a ¡°6% Moly¡± grade due to the molybdenum content.
Moly family has the ability to withstand high temperatures and maintain strength under volatile conditions.
316 stainless steel has more carbon in it than 316L. This is easy to remember, as the L stands for “low.”
316L is very similar to 316 in almost every way.?
316L, however, is a better choice for a project that requires a lot of welding because 316 is more susceptible to weld decay than 316L (corrosion within the weld).
316 can be annealed to resist weld decay.
316L also is a great stainless steel for high-temperature, high-corrosion uses, which is why it’s so popular for use in construction and marine projects.
904L grade stainless steel is unlike any other steel. Due to its extra amounts of chromium, molybdenum, nickel and copper, 904L steel features superior resistance to corrosion, rust and acids.
Alloy 347 (UNS S34700) is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321 (UNS S32100).
