About Stainless Steel 321 Pipe & Tube
Stainless steel 321/321H is a more stable variant of 304 stainless steel. This alloy is tempered with titanium, in addition to the 18/8 chromium-nickel ratio, providing the alloy with additional resistance to intergranular corrosion caused by heat treatment. It is suitable for use in the temperature range of 430 to 816°C. These alloys possess excellent mechanical strength and are corrosion-resistant even when immersed in water. Heavy welding machines and constantly changing surroundings are the most common uses. The addition of titanium, while enhancing strength, adversely affects the machinability of Type 321. The metals can only be welded using specific welding methods. Type 321 alloy has excellent formability and does not need to be connected after welding, thereby extending this limit. This grade can withstand temperatures as low as cryogenic. It is preferred over 304 when stronger creep and tear resistance is required. Both varieties, however, are prone to stress corrosion cracking.
321H stainless steel is a high-carbon variant of 321. Although it has the same machinability as 321, heat treatment cannot harden it. High carbon levels improve tolerance to high temperatures. Consequently, 321H is preferable when 321 cannot manage temperatures, particularly over 538°C. Furthermore, the inclusion of niobium improves intergranular corrosion resistance. 321H offers some acid corrosion resistance in a variety of conditions. Even though its resistance is strong at low temperatures, it can endure a 10% acid solution at high temperatures. The main exceptions are chlorine and sulfuric solutions, which it does not work well, regardless of temperature. Due to their almost similar chemical composition and features, 321 and 321H may be dual certified.
