What are Duplex Steel 31803 Round Bars?

Duplex Steel 31803 Round Bars are a type of round bar made of UNS S31803 grade duplex stainless steel that exhibits both the characteristics of austenitic as well as ferritic stainless steel. It consists of about 22% of chromium, 5-6% of nickel, and 3% of molybdenum. It has a structure that imparts greater strength, greater resistance to chloride stress corrosion, and greater toughness compared to regular stainless steels. It is best for industries that require both high mechanical strength and greater resistance to corrosion.

Meta Aerospace stands as one of the leading Duplex Steel 31803 Round Bars Manufacturers based on our quality assurance, on-time delivery, and customer satisfaction. We manufacture our round bars through state-of-the-art production processes to ensure uniformity, close tolerance, and superior surface quality. All these bars pass rigorous quality inspections to meet international standards including ASTM A276, ASTM A479, and UNS S31803 specifications.

A key benefit of Duplex Steel 31803 Round Bars is their elevated yield strength of nearly twice that of austenitic grades of stainless steel. It makes it possible for designers to minimize section thickness without weakening the structure, resulting in both weight savings and cost benefits. It also possesses superior resistance to localized types of corrosion, including pitting, crevice corrosion, and stress corrosion cracking. Its thermal conductivity is greater, and thermal expansion less, in comparison to austenitic grades, resulting in it having better dimensional stability.

Uses and Applications Duplex Steel 31803 Round Bars?

These bars play a critical role in the aerospace sector because of their high temperature oxidation resistance and strength.

• In chemical processing applications, these bars are utilized in the production of heat exchangers, pressure vessels, and reactor tanks as a result of their superior acid corrosion resistance and resistance to chloride attack.
• The aerospace industry depends upon Titanium Grade 5 for airframes, engines, and hydraulic components where strength and lightness are very crucial in performance and in fuel efficiency.
• In the marine sector, Duplex Steel 31803 Round Bars find application in shipbuilding, offshore rigs, and seawater desalination plants where resistance to seawater corrosion is essential.
• The medical profession utilizes these bars in orthopedic implants, dental devices, and surgical devices due to their biocompatibility and non-reaction in contact with human tissue.
• In nuclear and fossil-fuel based power generation, Titanium Grade 5 is utilized in condenser tubes and in coolers on account of its erosion resistance as well as resistance to corrosion.
• In the case of the oil and gas industry, Titanium Grade 5 is essential for offshore platforms and equipment that demand high strength and resistance to corrosion in extreme conditions.
