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.
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.
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).
The addition of copper to this grade gives it better corrosion resistance than conventional chromium-nickel stainless steels, especially against sulfuric, phosphoric and acetic acids. However, the use of hydrochloric acid is limited.
It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 ¨C 1500¡ãF (427 ¨C 816¡ãC).?
Stainless steel 904L / 1.4539 material can be used to make hot and cold rolled sheet and strip, semi-finished products, bars, rolled wire and profiles, as well as seamless and welded pipes for pressure applications.
The alloy has good oxidation resistance and creep strength to 1500¡ãF (816¡ãC). It also possesses good low temperature toughness.
Alloy 904L outperforms other austenitic stainless steels due to the higher degree of alloying of nickel and molybdenum.
Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 ¨C 0.10) version of the alloy.
The high chromium content promotes and maintains a passive film that protects the material in many corrosive environments.
When selecting stainless steels that must withstand corrosive environments, austenitic stainless steels are often used.
The high amounts of nickel and chromium in austenitic stainless steels provide excellent mechanical properties, as well as excellent corrosion resistance.
