fasteners. We have made it simple for our clients to obtain their required grades at the same
measures. Stainless steel 347 and 347H grades are manufactured at a rapid speed in an industry
where quality is essential for every client.
347 Stainless Steel Fasteners are meticulously tested by a team of specialists to ensure that they
are safe to perform and use in the absence of any flaws. It contains a low carbon content material
that improves weldability and reduces the possibility of concentrated resistance to corrosion
throughout the weld.

Properties of SS 347/347H Fasteners:
- 1) SS 347 Fasteners are commonly used because they are easily formable in a broad range of sizes and
diameters. However, for our client's specific requirements, we offer this capability in stainless
steel 347H washers and their relevant grades.
- 2) Pitting resistance to corrosion is one of the advantages of Stainless Steel UNS S34700 Fasteners.
When high temperatures are present, 347H SS Fasteners are highly recommended for usage because they
have stress and creep-rupture properties.
- 3) SS 347 / 347H Fasteners are becoming the next requirement in food processing and petroleum
refinery equipment due to their incredible ability to retain after a long and rigorous procedure.
Aerospace and electrical instruments are two significant areas where SS 347H Fasteners are in great
demand.
