Common Applications Of 2205
As they contain the next chromium content material than commonplace 3xx grades, their Pitting Resistance Equivalent Number (PREN) is higher, indicating increased resistance to pitting corrosion. Grade 2205 chrome steel exhibits glorious corrosion resistance, much greater than that of grade 316. It resists localized corrosion sorts like intergranular, crevice and pitting. This grade is immune to chloride stress corrosion cracking (SCC) at temperatures of a hundred and fifty°C.
Grade 2205 stainless steels are apt replacements to austenitic grades, especially in untimely failure environments and marine environments. Ferritic Stainless grades resist corrosion and oxidation, while remaining immune to stress and cracking.
It is probably the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless-steel grades. It demonstrates good fatigue power, as well as outstanding resistance to stress-corrosion cracking, crevice, pitting, erosion and basic corrosion in extreme environments. Sanmac® 2205 is a 22% Cr duplex chrome steel with improved machinability as standard.
The excessive chromium, molybdenum and nitrogen contents leads to a Pitting Resistance Equivalent number (PREN) of 33-34. Duplex Alloy 2205 is a two-part, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel.
What is alloy2205?
They are all fully magnetic all the time. The best known duplex grade, 2205, resists corrosion even better than 316 because it contains 22% of chromium and 3% of molybdenum. Both are magnetic, because both are ferritic.
- As a duplex stainless-steel, it combines the desirable aspect of properties of both austenitic and ferritic grades.
- In addition to the improved corrosion resistance in contrast with the 300 series stainless steels duplex steels even have higher power.
- Both the low nickel content material and the high power (enabling thinner sections for use) give vital price benefits.
- Alloy 2205 is a 22% Cr duplex stainless steel, provided in the solution annealed condition.

Is 2205 stainless steel magnetic?
Grade 2205 for High Corrosion Resistance and Strength. Combining many of the beneficial properties of both ferritic and austenitic steels, 2205 is the most widely used duplex stainless steel grade. Its high chromium and molybdenum content gives the stainless steel excellent corrosion resistance.
ASTM A240 304L Stainless steel plate 
Both the low nickel content material and the high strength (enabling thinner sections for use) give vital value benefits. In addition to the improved corrosion resistance in contrast with the 300 sequence stainless steels duplex steels even have larger strength.
Combining lots of the useful properties of both ferritic and austenitic steels, 2205 is the most extensively used duplex stainless-steel grade. Its high chromium and molybdenum content gives the stainless-steel excellent corrosion resistance. The microstructure offers resistance to emphasize corrosion cracking and ensures high strength. As with all corrosion-resistant alloys, duplex stainless steels can undergo corrosion when uncovered to suitably corrosive circumstances.
