Stainless Steel Alloy 321H

Type 321H is an austenitic titanium-stabilized stainless steel renowned for its general corrosion resistance. This type of Type 321 stainless steel with a higher carbon content offers numerous advantages, including:

Excellent oxidation resistance up to 1500°F (816°C).

Excellent low-temperature tenacity

Comparable resistance to corrosion and machinability to Type 304

Easily welded by the majority of common methods

Very plastic and easy to shape

Due to the Type 321H's characteristics and qualities, it is utilized in a variety of industries and vital applications, including:

Expansion joints

Processing of chemicals and petrochemicals

Pharmaceutical manufacturing

Treatment of waste with thermal oxidizers

Food processing equipment and storage facilities for aerospace purposes

To acquire the Type 321H designation, a stainless steel must have the following chemical composition. Importantly, Type 321H contains significantly more carbon than Type 321:

Fe equilibrium Cr 17-19%

Ni 9-12% \sC 0.04-0.10%

Si 18-20%

Mn 2% max

P 0.045% max

S 0.03% max N 0.10% max

Ti 0.70% max

SSM's Type 321H metals fulfill the most prestigious international specifications, including ASTM, ASME, and AMS.
