DC Engineering is a dedicated manufacturer of 2205 duplex Studs with decades of experience, a quality control system, and advanced tools utilised in the manufacturing of these stud bolts. We manufacture 2205 duplex steel stud bolts in accordance with national and international standards and norms.
UNS S31803 Duplex Studs are high steel grade and have high fatigue resistance and corrosion resistance in most of the high temperature atmosphere. We have different kinds of fasteners such as Duplex hex head fasteners, duplex hex bolt, duplex threaded rod. Duplex washers, and many more.
The applications that employ Duplex 1.4462 Grade Coated Studs are oil and gas industries, marine industries, chemical industries, paper and pulp industries, etc. WE have lean duplex and standard duplex in the wide range of duplex steel grade selections. Duplex 2205 stud bolts are identified with specific properties that suit different environments. The chemical composition of duplex 2205 material makes chromium, nickel, and molybdenum within the composition. Duplex 2205 stud bolts are economically effective and less than other duplex grades and have high demand in the market. Duplex 2205 stud bolts play an excellent role against corrosion resistance and strength that is obtained from ferric steel types and austenitic steel type grades. Duplex 205 hex bolts offer far better strength than regular stainless steel after pressure hardening. This grade of stud bolts is generally considered as flexible, and can be used because of a better elongation rate than any other grades of steel. Feel free to contact us.
