Ranflex Metals 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.
