Laboratory exams reveal good resistance to stress corrosion cracking of Sandvik SAF 2205™. The diagram signifies the temperature-chloride range within which Sandvik SAF 2205 and the standard steels ASTM TP304L and ASTM TP316L have low susceptibility to stress corrosion cracking. Most common austenitic kind steels don’t stay magnetic after the answer heating process.
Duplex is a grade of metal which accommodates austenite and ferrite elements in mixtures. Duplex grade is extremely corrosion resistant and pitting resistant. Duplex 1.4462 Sheet is very tough enough strange ferritic chrome steel sheets.
Results from these exams are presented in determine 7. The diagram signifies the temperature-chloride range inside which Sandvik SAF 2205™ and the standard steels ASTM 304L and ASTM 316L can be utilized with out danger of stress corrosion cracking.

Our stainless production range
- Duplex stainless steels are far less susceptible to this sort of corrosion.
- Laboratory tests have shown the good resistance to emphasize corrosion cracking of Sandvik SAF 2205™.
- The diagram signifies the temperature-chloride vary within which Sandvik SAF 2205™ and the standard steels ASTM 304L and ASTM 316L can be utilized without danger of stress corrosion cracking.
- Results from these checks are presented in determine 7.
This mixture of properties can imply some compromise when compared with pure austenitic and pure ferritic grades. Sandvik SAF 2205™ possesses higher energy and better corrosion resistance than ordinary austenitic stainless steels. It, therefore, additionally possesses higher fatigue strength beneath corrosive conditions than such steels. The normal austenitic steels of the ASTM 304L and ASTM 316L types are susceptible to stress corrosion cracking (SCC) in chloride- bearing solutions at temperatures above 60 °C (a hundred and forty °F).
Testing based on ASTM A262 PRE (Strauss test) constitutes no drawback for welded joints in Sandvik SAF 2205™, which move without reservation. Testing according to ASTM A262 PRE (Strauss´ take a look at) presents no problems for welded joints in Sandvik SAF 2205™, which cross with out reservations. 1.4462 Duplex Plate is one of the most used stainless steel alloys right now. It has a middle vary of mechanical properties of stainless steel alloys which makes it utilized in many applications.
The impact power of welded Sandvik SAF 2205™ is also good, regardless of the influence power values in the as-welded condition being slightly decrease than for weld-free material. Tests show that the impact energy of material, welded by the use of gas-shielded arc welding, is good in each the weld metallic and the warmth-affected zone right down to -50°C (-58°F). At this temperature, the influence strength is a minimal of 27 J (20 ft lb). Resistance to stress corrosion cracking (SCC) in neutral chloride options with an oxygen content material of about 8 ppm.
Duplex 1.4462 Hardness
The results of laboratory checks, to determine the important temperature for the initiation of pitting (CPT) at different chloride contents are proven in Figure 6. The chosen testing situations have yielded outcomes that match nicely with practical experience. Thus, Sandvik SAF 2205™ can be used at considerably larger temperatures and chloride contents than ASTM TP304 and ASTM TP316 without pitting. Sandvik SAF 2205™ is, due to this fact, much more serviceable in chloride-bearing environments than commonplace austenitic steels.
