Vision Alloys produces Duplex S31803 Fasteners in all grades of duplex, to customer specification.ALLOY 31803 is a chromium nickel molybdenum austenitic and ferritic grade. It has improved resistance to stress corossion cracking, piiting, crevice corrossion and high strengths in comparison to other stainless steel grades. It has very good oxidation resiatnce at high temperatures. However, it is prone to embrittlement at 475 Degree celcious if exposed for more than 2 hours. It is widely used in brewing , power generating equipments and wide varierty of marine and oil and gas applicants. If we do not have your Duplex S31803 Fasteners in stock (Inch or Metric) we can have these manufactured to your specification.


S31803 Duplex Stainless Steel Fasteners


Vision Alloys is one of the most astonishing manufacturers and suppliers of metal equipment and products. These products are highly used for industrial applications. UNS S31803 fasteners are used for a vast range of applications. We usually offer all types of fasteners in various sizes, shapes, and dimensions. The application of these fasteners depends upon the S31803 material and the usage and temperature where these fasteners are getting installed.

Duplex S31803 fasteners are made from austenitic and ferritic microstructures. The grade has excellent quality and characteristics as it includes high amounts of chromium, nickel, and molybdenum content which provides excellent resistance from pitting and forging. Outstanding chemical and mechanical properties offer superior efficiency and strength to the S31803 duplex stainless steel.
