Duplex Steel Fasteners
ACE ALLOYS LLP is one of the leading manufacturing house & trader for high quality Duplex Steel Fasteners , which has shown excellent machining properties. Even when the ductility is adequate, higher forces are required to form the material, for example in tube bending.
The heat treatment in Duplex Steel Nuts should be followed by subsequent rapid cooling in water or air, where this treatment applies for both solution annealing and stress relieving and the latter can in special cases be done at 500 Degree C – 550 Degree C. These are generally more demanding to machine than conventional austenitic stainless steel, due to the higher hardness.
Duplex Steel Bolts offered by ACE ALLOYS generally offer an excellent corrosion resistance, but has advantages in oxidizing media such as nitric acid solutions due to its low molybdenum content. It is an excellent duplex stainless steel with nitrogen added for improved welding properties. The metallurgy of Duplex Steel Washers from ACE ALLOYS is much more complex than for austenitic or ferritic steels, where this factor means that they are more difficult to produce at the mill and to fabricate. They are highly alloyed and have a corrosion resistance comparable to high performance austenitic like 254 SMO.
Typical applications for Duplex Steel Stud Bolts are desalination plants, seawater systems, flue - gas cleaning, umbilicals, storage tanks and pressure vessels. ACE ALLOYS also offer these Duplex Stainless Steel Fasteners in different sizes, shapes and designs as per customers’ specifications at affordable rates.
