The Duplex Stainless steel UNS S31803 bolts are used as two-phase alloy and are most widely used for bolts. This is mostly used because of its yield strength and demonstration of good fatigue strength. These bolts are durable in long-lasting temperatures and places where the high strength of durability is required.


Specifications and sizes-

These bolts are specified as ASME SA-182 (F51), SA-240, SA-798, SA-790, SA-815, ASTM A182 (F51), A240, A276, A479, A789, A790, A815, A928, A988 and SAE J405. Along with these, there are some additional standards of AFNOR Z3 Cr Ni 22.05 AZ and DIN standard of WNr 1.4462. All these standards make them a good standard in their quality.


And the size of Duplex Stainless steel UNS S31803 bolts varies from 3mm to 200 mm while their length ranges from M02 to M30. And they are tested in quality by the standards of IS, BS, and ASTM. And to ensure this quality of products packaging also plays an important role in bolts manufacturing. And for this development of and a process of all the staffs is also an important factor.
