Nextgen Steel & Alloys is a reputed firm in the market to supply SS 321/321H Buttweld Fittings. Our fittings are widely accepted as a result of top-class quality. These buttweld fittings are connections between components in the system. It is a wide variety of components mostly used as bends, reducers, cross, elbows, stub ends, etc., in different types depending on form, size, length, dimensions and other specifications. Applications of these fittings are in industries like Off-Shore Oil Drilling Aircraft exhaust manifolds Petrochemicals Specialty Chemicals Sea Water Equipment Pharmaceuticals Expansion joints Heat Exchangers Condensers Power Gas etc.
Nextgen Steel & Alloys supply durable and strong SS 321 Buttweld Fittings unaffected when exposed to pitting and crevice corrosion in humid chloride surroundings and prevent stress corrosion cracking. It is also capable of sustain chlorides in clean water at ambient temperatures. These fittings exhibit excellent resistivity in aqueous corrosive circumstances. These fittings are non-magnetic and frequently used in super-heater and after burner components, compensators and expansion bellows.
SS 321H Buttweld Fittings are improved with higher temperature strength and enhanced weldability that uses standard fusion methods. Thus these fittings are strong, rigid, and mostly used in high thermal levels applications such as aircraft exhaust stacks and manifolds, jet engine parts and weld equipment.
SS 321 is basic austenitic steel of Nickel-Chromium stabilized by the adding together of Titanium. It exhibits better strength, excellent resistance to scaling and phase stability and resistance to consequent aqueous corrosion. SS 321H is an austenitic general purpose steel stable against carbide precipitation. It is only hardened using a cold working technique, and in the annealed condition, it is non-magnetic. Titanium suppresses chromium carbide precipitation to reduce intergranular corrosion.
Nextgen Steel & Alloys has considerable manufacturing experience in SS 321/321H Buttweld Fittings of national and global quality. We offer excellent and fast service with technical help for consumers. Our technical team helps to choose proper specifications to fit in the system. Our fittings are formed by excellent material using relevant processes. Our upgraded techniques have minimized errors during production. It is also further tested for defects as well as all specified parameters are tested during quality evaluation. We distribute quality certified fittings with fast delivery.
