Sachiya Steel International is one of the Leading Manufacture And Exporter of Duplex S31803 Wire, which is also alloyed with tungsten and / or copper. Duplex S31803 Wire takes its name from its two-phase microstructure of ferrite and austenite in approx. equal proportions. Duplex S31803 Coil Wire contains over 20 % chromium and approximately 5 % nickel, and it is part of the group of stainless steels. In Duplex S31803 Coiled Wire, the minimum chromium, molybdenum and nitrogen content has been increased compared to other material.
Duplex S31803 Wire acquires their optimum properties with a balanced ferrite – austenite ratio of approximately 50 / 50. Compared to the austenitic stainless steels, Duplex S31803 Wire contain less nickel (approx. 4 % to 8 %), which results in very good value for money. Duplex S32205 Wire may be used in the temperature range between –40 Degree C and 280 Degree C. The typical composition of Duplex S32205 Wire is illustrated with 25 % chromium, 7 % nickel, 4 % molybdenum and 0.25 % nitrogen.
Duplex S32205 Wire is also distinguished by its increased resistance to pitting, crevice and stress corrosion cracking, and an additional increase in its mechanical strength values. Duplex S32205 Wire is currently the most widespread variants and is distinguished by outstanding application properties and by high availability in all the relevant product forms.
