Size  :1220*2440*1mm

Grade :  AISI   321 

Chemical Properties

321 stainless steel is a titanium-stabilized austenitic stainless steel (similar to 304 but with added titanium to prevent chromium carbide precipitation). It offers excellent high-temperature resistance and intergranular corrosion resistance.

 Typical Chemical Composition (%):

Element Composition

Chromium (Cr) 17.0 – 19.0

Nickel (Ni) 9.0 – 12.0

Carbon (C) ≤ 0.08

Manganese (Mn) ≤ 2.0

Silicon (Si) ≤ 1.0

Phosphorus (P) ≤ 0.045

Sulfur (S) ≤ 0.03

Titanium (Ti) ≥ 5×C (min. 0.4%)

Iron (Fe) Balance

Key Features

✔ High-temperature stability (up to 800-900°C)

✔ Resists carbide precipitation (sensitization) during welding

✔ Good oxidation & corrosion resistance (better than 304 in some environments)

 Applications

Due to its heat resistance and weldability, 321 stainless steel is widely used in:

Aerospace & Jet Engine Components (exhaust systems, combustion chambers)

Chemical & Petrochemical Equipment (heat exchangers, pressure vessels)

 High-Temperature Pipelines & Boilers (thermal stability)

 Automotive Exhaust Systems (manifolds, catalytic converters)

 Food Processing & Pharmaceutical Equipment (where welding is required)

 Heat Treatment & Furnace Parts (due to oxidation resistance)
