AISI 444 Round Bars

Jayant Impex Pvt Ltd, India, Maharashtra, Khopoli, Mumbai are leading AISI 444 Round Bars supplier, exporter, trader, wholesaler, stockiest.

*AISI 444 contains molybdenum alloying and rather high 18 % chromium content & the grade has excellent corrosion properties. Corrosion resistance is comparable to the austenitic grade 4401 / 4404 in various applications. As a result of molybdenum alloying, strength values for 1.4521 are higher compared to grade 1.4509.

*Stabilization is made using both titanium and niobium. As a result of niobium alloying, a fully stabilized microstructure can be achieved with lower titanium levels, which improves the surface properties. Elongation to fracture values up to 30% (A80) can be achieved.

*These properties make grade 1.4521 an ideal material for heat exchangers, boilers and water heaters. This grade may also be used in pipes for tap water and in other applications within drinking-water environments. 1.4521 grade is, for example, approved for use of drinking water applications by German (DVGW) and Swiss (SVGW) authorities. Another application having similar requirements is in solar water heaters.

*Corrosion resistance properties of AISI 444:

Grade 1. 4521 is Molybdenum  alloyed ferritc steel, and because of this, resistance to localized corrosion is close to grade 1.4404 / AISI 316 “acid-proof” austenitic. 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. Optimal material performance is usually achieved through efficient design, correct post-weld treatment and regular cleaning during use (if applicable).

The nickel-free ferritic grades have excellent resistances to chloride induced stress corrosion cracking.

*Formability properties of AISI 444:

Can be readily cold-formed by all standard processes. It is particularly suitable for deep drawing.  The deep drawability of Outokumpu 4521 is comparable to that of deep drawing quality carbon steels.

AISI 444 has a lower work hardening rate than standard austenitic grades. This characteristic makes the grade 444 less suitable for applications involving stretch forming.  For the same reason, 444 is more easily cold formed and machined. The forces needed in cold-forming and machining are similar to those needed for low-alloyed carbon steels.

Normally, 444 is not prone to the “ridging and roping” surface defect in deep drawing.

*Welding properties of AISI 444:

4521 produced by Outokumpu has low C and N contents. It is also stabilized with titanium and niobium which reduces or prevents the sensitation and formation of martensite. The stabilization gives this ferritic steel better weldability than many of the previously presented ferritic steels. The weldability is mainly limited by grain growth in the HAZ (heat affected zone), so the heat input must be kept to a minimum. Austenitic fillers are mostly used.
