SS 321 and SS 321H Seamless Tubing is a type of seamless stainless steel. It is stabilized by the addition of titanium in it. Titanium does not allow the formation of chromium carbide in it. If the industrial product is made using this alloy then it adds several features to the product like amazing resistance against intergranular corrosion, and also provides resistance against high temperature. Moreover, it also provides it with higher stress rupture properties and higher creep properties. This alloy contains a higher percentage of carbon in comparison to than other alloys. Also, alloy could be used for absolute phosphoric acid at low-temperature range and diluted acids at high temperatures. This material is the best choice because it can be used for a temperature up to 900 degrees Celsius.

SS 321 Seamless Tubing is preferred in many companies and industries which includes paper and pulp industries, petrochemical industries, chemical industries, water processing industries, oil refineries, gas-related industries, food processing industries, dairy industries, marine industries, onshore and offshore industries and many more.
SS 321H Seamless Tubing both are made of austenitic stainless steel. They possess several benefits, where the first one is resistance to higher temperatures, excellent intergranular corrosion resistance has low-temperature toughness, resists oxidation at higher temperatures. Also has higher stress rupture properties and higher creep properties. Moreover, the addition of titanium in it prevents the chances of chromium carbide precipitation in it. Also, it can be welded and bent very easily that adds to its benefits. These tubing’s are provided in different sizes and shapes as per the need of customers. The SS 321H Seamless Tubing differs from 321 as it contains higher carbon percentage in comparison to the other one. Some tests performed for better quality products include corrosion resistance test, pitting test, temperature resistance tests, and material testing according to standard procedures and so on. The packaging is also done properly so that the product should not be damaged.
