2205 Stainless Steel Vs 304

We still use 304 stainless steel which scores at a 20 but only in interior applications or in environments at least 5 miles from saltwater.

2205 stainless steel vs 304. Although 2205 has good high temperature oxidation resistance this grade like other duplex stainless steels suffers from embrittlement if held for even short times at temperatures above 300 o c. With carbide tooling positive rake angle and c 5 and c 6 grades for. On the other hand 2205 scores at a 34 making it fully corrosion resistant to salt water contaminants. In short 2205 stainless steel is going to be more durable longer lasting and safer in the long.

2205 is annealed at 1020 1100 o c followed by rapid cooling. 304 stainless steel is the most versatile and widely used austenitic stainless steel in the world due to its corrosion resistance. Ss 304 ss 316 ss 301 ss 904l and 303 etc the special advantages of duplex 2205 stainless steel are strength about twice that of austenitic stainless steel and excellent resistance to chloride scc and pitting corrosion. 304 316l 2205 ultimate tensile mpa 515 515 700 0 2 proof strength 205 205 570 hardness brinell max 200 200 290 differences to machine and cut.

The difference between 2205 duplex stainless steel and 304 316 duplex 2205 stainless steel is a type of stainless steel which is different from austenitic 304 316 stainless steel has better mechanical properties chemical properties and higher prices. Cutting speed is about 20 slower on 2205. If embrittled this can only be rectified by a full solution annealing treatment. 2 type 2205 code plus two duplex stainless steel quenching.

304 stainless is also cheaper in cost compared to 316 another reason for its popularity and widespread use. This treatment applies for both full solution annealing and stress relief annealing. 2205 has been a practical solution to chloride stress corrosion cracking problems experienced with 304 304l or 316 316l stainless. Clamping products such as glass clamps and spigots.

2205 is a duplex austenitic ferritic stainless steel containing about 40 50 ferrite in the annealed condition. Grade 2205 stainless steel has as a ferritic autentistic microstructure consisting of 50 ferrite and 50 austenite hence the term duplex. Machining of 2205 is harder than 304 or 316 and you will use more consumables. Compared with the conventional 300 series stainless steel e g.
