  • Packing

Alloy 321 (UNS S32100) is titanium stabilized austenitic stainless steel plate with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 - 1500°F (427 - 816°C). The alloy resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness.

Alloy 321H (UNS S 32109) stainless steel plate is the higher carbon (0.04 - 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000oF (537°C). In most instances, the carbon content of the plate enables dual certification.

Alloy 321 stainless steel plate cannot be hardened by heat treatment, only by cold working. It can be easily welded and processed by standard shop fabrication practices.

General Properties :

Austenitic Stainless Steel 321 (UNS S32100) / 321H (UNS S32109) is Titanium stabilized Austenitic Stainless Steel Plate / Sheet with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C). The 321 / 321H Alloy Plate & Sheets resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness.

Stainless Steel Grade 321 / 321H Plates & Sheets is the higher carbon (0.04 – 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000oF (537°C). In most instances, the carbon content of the plate enables dual certification.

SS 321 / SS 321H Stainless Steel Plate & Sheets cannot be hardened by heat treatment, only by cold working. It can be easily welded and processed by standard shop fabrication practices.

Fabrication Data :

ASTM A240 Grade 321 /321H Stainless Steel Plate & Sheet can be easily welded and processed by standard shop fabrication practices.

Cold Forming :

The alloy is quite ductile and forms easily.

Machining :

The cold work hardening rate of SS 321 / SS 321H Stainless Steel Plate / Sheet makes it less machinable than 410 stainless steel, but similar to 304.

Welding :

SS 321 / SS 321H Stainless Steel Plate can be readily welded by most standard processes. A post weld heat treatment is not necessary. Excellent weldability by all standard fusion methods, both with and without filler metals. AS 1554.6 pre-qualify welding of SS 321 / SS 321H with Grade 347 rods or electrodes; high silicon version of 347 is also pre-qualified for welding of 321 / 321H.

Possible Alternative Grades

Grade

Why it might be chosen instead of 321

304L

The requirement is for resistance to intergranular corrosion, not for high temperature strength

3CR12

Only mild “high temperature” environment is present up to about 600oC.

304H

Only mild “high temperature” environment is present up to about 800oC.

310

The temp3erature of the operating environment is up to about 1100oC – too high for 321 or 321H.
