Kencotube is one of the leading manufacturing house & trader for high quality Duplex Steel Fasteners, which are generally more demanding to machine than conventional austenitic stainless steel, due to the higher hardness. Even when the ductility is adequate, higher forces are required to form Duplex Stainless Steel Fasteners, 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. Meanwhile, the latter can be done in special cases at about 500 Degree C – 550 Degree C. Duplex Steel Bolts is a lean stainless steel that generally offers a similar corrosion resistance as ASTM 316L, but has advantages in oxidizing media such as nitric acid solutions due to its low molybdenum content.
The metallurgy of Duplex Steel Stud Bolts 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. Duplex Steel Screws are highly alloyed and have a corrosion resistance comparable to high performance austenitic steels. Manganese, silicon, or aluminum is added in these Duplex Steel grades during the steelmaking process to remove dissolved oxygen, sulfur and phosphorus from the melt. Typical applications for Duplex Steel Washers are desalination plants, seawater systems, flue-gas cleaning, umbilicals, storage tanks and pressure vessels. We also offer these steel in best prices to our clients.
