Outokumpu 1.4521
Type 18Cr-2Mo-Ti stainless steel: EN 1.4521, AISI 444
Applications
- Boilers, water heaters and heat exchangers are typical applications for grade 1.4521. Also storage tanks and tubes are suitable applications.
- This grade may also be used in pipes for tap water and in other use for drinking-water contexts.
- High chromium content and addition of molybdenum makes this grade an alternative for "acid-proof" austenitic grades for some selected applications.
Welding
- Conventional welding methods and filler materials applied to austenitic 300-series can be used. Heat input in welding should been kept in a minimum level.
- Shielding gases should be based on Ar/He and not to contain hydrogen, nitrogen or carbon dioxide, respectively.
- Generally welded structures show lower ductility compared to that of base material.
Fabrication
- Grade 1.4521 can be formed using typical forming processes like folding, bending, drawing, etc.
- It has higher minimum proof strength than standard austenitic stainless steel grade 1.4301 / AISI 304 in combination with lower work hardening behavior.
- Due to the stabilization, the r-value is higher compared to the non-stabilized ferritic stainless steel such as 1.4016.
- These characteristics means excellent deep-drawability.
Corrosion resistance
- Outokumpu produces grade 1.4521 with a typical chromium content of 18 wt-% and molybdenum content of 2 wt-%.
- Resistance to localized corrosion is close to grade 1.4404 / AISI 316 "acid-proof" austenitic.
- Grade 1.4521 is not susceptible to chloride induced stress corrosion cracking.
- In chloride containing solutions pitting and crevice corrosion is possible depending on various parameters like chloride concentration, temperature, pH value, redox potential, crevice geometry and others.
- The best material performance is reached usually with the help of adequate design, correct post-weld treatment and regular cleaning during use (if applicable)
