Stainless Steel 347 Fasteners

ASME SA194 347H High Temperature Fastener Manufacturer in India

Buyers for numerous industrial applications highly demand fasteners. Nitron Alloys Overseas is a respected manufacturer known for providing an extraordinary range of Stainless Steel 347 / 347H Fasteners. The material used for the manufacturing of these Fasteners is made sure of having the desired quality and is procured from a trusted source. We deal with a massive customer base while offering these Fasteners at economical rates accompanied by magnificent service policies.

Stainless Steel 347 / 347H are the grades of austenitic stainless steel having different carbon content. Stainless Steel 347H contain more carbon content in it than Stainless Steel The Fasteners made out of these grades are perfectly suitable for high-temperature applications as a result of columbium content in it. It also has an excellent combination of columbium and tantalum that make it able to prevent intergranular corrosion. Our Fasteners provide increased resistance to corrosion, especially in a highly corrosive atmosphere. The material is primarily non-magnetic but develops magnetic properties when heat treated.


Nitron Alloys Overseas has an excellent workforce that, through dedication and efforts, has set new standards of quality of SS 347 / 347H Fasteners . We focus on making our Fasteners dimensionally accurate. The high quality of these Fasteners allows them to sustain through impact loadings and crucial working conditions. Our skilled workforce use highly automated machinery and tools to meet the desired dimensional requirements of the customers. A team consists of field experts, and knowledgeable engineers supervise the entire process and ensure that the standard operating procedure is getting followed. We also have a hi-tech storage facility that allows us to maintain an extra stock of these Fasteners. This stock helps us to complete urgent requirements.


Nitron Alloys Overseas follows strict quality considerations and checks every Stainless Steel 347 / 347H Fastener under different quality tests during the whole production process. These tests define the usability of the Fasteners along with the service life. Nitron Alloys Overseas is serving a large customer base by making Stainless Steel 347 / 347H Fasteners available at minimal prices. We have always given priority to the customer's satisfaction and have never delayed the orders on the same path.
