Duplex – stronger than steel!
In Marinething's range you will find boat accessories in stainless and acid-resistant steel as well as in Duplex. We have high quality standards and we only sell the best on the market.
What is Duplex?
Duplex steel belongs to the group stainless- and acid resistant steel and it has very high strength. It is comparable to steel in the higher strength classes. There are five duplex groups; from lean to hyper. What gives duplex steel its character is the balance between austenitic and ferritic two-phase structures (ratio 50:50). Duplex therefore consists of more chromium than the pure austenitic steel and of lower nickel contents than other nickel-based products. This contributes to the duplex steel's high strength and it gives the steel its stability. It is corrosion resistant and has excellent mechanical properties. Products such as screws, washers, chains, etc. become particularly durable when they are manufactured in duplex steel.
Duplex is available in the following standards:
AFNOR Z 5 CNDU 21.08
AISI/ASTM 318 LN
BS 318 S 13
SS 2377
UNS S 31803
AFNOR = Association française de normalisation
AISI = American Iron and Steel Institute
ASTM = American Society for Testing and Materials
BS = British Standards
SS = Swedish Standard
UNE = Spanish Standards
UNS = Unified Numbering System
