Alpha Overseas is well known in the industry for its production and distribution of SS 321/321H Olet Fittings. Fittings can be made from SS 321/ 321H grades since they highly resist intergranular corrosion. Due to their superior mechanical qualities, our Olet Fittings are beneficial at high temperatures. It has many advantageous qualities, which eliminate the corrosion strain. The SS 321/ 321H has exceptional toughness and exhibits creep and rupture qualities. We are a reputable company that produces and exports a large selection of SS 321 / 321H Olet Fittings resistant to stress corrosion cracking from polythionic acid. Today, virtually entirely for service within the sensitizing temperature range, stainless steel 321 Olet fittings are employed (450 ℃ -850 ℃). Jet engine parts frequently use stainless steel 321H Olet fittings because they have exceptional oxidation resistance at high temperatures. We can offer the majority of projects, whether for stock items or specially produced products like Stainless Steel 321 Olet Fittings, thanks to our extensive inventory and superior processing capabilities.

Titanium has a larger affinity for carbon than chromium in Stainless Steel 321H Olet Fittings. Therefore titanium carbide precipitates within the grains instead of forming at the grain boundaries. Stainless Steel 321 Welding Olet Fittings may be more difficult to form than other austenitic grades if specific alloying components are present. Excellent weldability may be achieved with stainless steel 321H socket weld Olet fittings using all common fusion techniques, both with and without filler metals. Stainless Steel 321 Threading Olet Fittings are used in various crucial applications and sectors due to their characteristics and properties. Because it is relatively pliable and forms quickly, stainless steel 321H flexible Olet fittings have a very high corrosion resistance thanks to the chromium remaining in the solution. Even in low concentrations, sulfuric acid service and chloride solutions harm the performance of stainless steel 321 nipple Olet fittings.
SS 321/ 321H resists stress corrosion cracking from polythionic acid in hydrocarbon service. Our products are created with a quality that gives our customers reason to continue doing business with us. Heat cannot be used to harden the material SS 321/ 321H. Therefore, cold processes are needed.
