Description
ALLOY-926
Alloy 926 contains a high concentration of molybdenum and nitrogen, which makes it highly resistant to pitting and crevice corrosion in service. Copper increases its resistance to sulfuric acid, and nitrogen increases its overall strength. Also known as austenitic stainless steel, Alloy 926 is a special stainless steel that was developed on the basis of Alloy 904 L, which has been in use for a long time and is well-known in the industry (1.4539). Alloy 926 has a molybdenum concentration that is 6.5 percent higher than Alloy 904 L, which is a significant difference. In other words, Alloy 926 has higher corrosion resistance than other alloys, and it also provides better protection against pitting corrosion and crevice corrosion. This has the additional benefit of alleviating the stress corrosion that is caused by pitting corrosion. This stainless steel can be found in alloy 926, which has 0.2 percent nitrogen added to it, as well as other alloys.This stainless steel is a super-austenitic stainless steel that contains 25 percent nickel, 20 percent copper, and 6.2 percent molybdenum in every piece.
It has been designed to be extremely strong and corrosion resistant, resulting in a structure that is extremely stable.
The 25% nickel and 1% copper additions combined with chromium molybdenum improve the behaviour of the steel in many corrosive solutions encountered for example in chemical and petrochemical processes. The alloy behaves particularly well in sulphuric acid solutions and is well adapted for pollution control equipments (scrubbers...) The alloy is also seawater resistant and has extensively been used in offshore industry. The fully austenitic microstructure produced by the 25% nickel addition explains its high toughness at temperatures as low as -200°C (-328°F).
