Duplex Steel Pipe

Duplex Steel Pipe

Duplex Pipe was originally developed in Sweden back in the 1940’s . Duplex Pipes were originally created to combat corrosion problems caused by chloride-bearing cooling waters and other aggressive chemical process fluids.
Called Duplex Pipe because of its mixed microstructure with about equal proportions of ferrite and austenite, duplex stainless steels are a family of grades, which range in corrosion performance depending on their alloy content. The chemical composition based on high contents of Cr and Mo, improves intergranular and pitting corrosion resistance, respectively. Additions of nitrogen can promote structural hardening by interstitial solid solution mechanism, which raises the yield strength and ultimate strength values without impairing toughness. Moreover, the two-phase microstructure guarantees higher resistance to pitting and stress corrosion cracking in comparison with conventional stainless steels.

The first-generation grades were alloys of chromium, nickel and molybdenum and while they provided good performance characteristics, welds had low toughness due to excessive ferrite, which limited the use of Duplex pipe steel to a few specific applications.

Properties

High temperature metals or high temp alloys consist of Inconel/Incoloy, Nickel and Superalloys.

Machining

Inconel metals are difficult metals to shape and machine using traditional techniques due to rapid work hardening. After the first machining pass, work hardening tends to plastically deform either the workpiece or the tool on subsequent passes. For this reason, age-hardened Inconels such as 718 are machined using an aggressive but slow cut with a hard tool, minimizing the number of passes required. Alternatively, the majority of the machining can be performed with the workpiece in a solutionized form, with only the final steps being performed after age-hardening. External threads are machined using a lathe to "single point" the threads, or by rolling the threads using a screw machine. Holes with internal threads are made by welding or brazing threaded inserts made of stainless steel. Cutting of plate is often done with a waterjet cutter. Internal threads can also be cut by single point method on lathe, or by threadmilling on a machining center.

Joining

Welding inconel alloys is difficult due to cracking and microstructural segregation of alloying elements in the heat affected zone. However, several alloys have been designed to overcome these problems.

 

Inconel Fittings have an excellent mechanical properties and provide good resistance to oxidation. We offer inconel 625 rod, inconel 601 rod, inconel 800 rod, inconel 825 rod and inconel 600 rod. These pipes find extensive application in furnace muffles, electronic components, heat treating equipment, steam generator tubing, heat exchangers, etc.

Beryllium Copper Round Bar

Beryllium Copper Round Bar

Approx. Rs 2,500 / Kilogram


We are offering Beryllium Copper Round Bar to our clients. One of the highest strength copper-based alloys available on the market today is beryllium copper, also known as spring copper or beryllium bronze. The commercial grades of beryllium copper contain 0.4 to 2.0 percent beryllium. The small ratio of beryllium to copper creates a family of high copper alloys with strength as high as alloy steel. The first of the two families, C17200 and C17300, includes high strength with moderate conductivity, while the second family, C17500 and C17510, offers high conductivity with moderate strength. The principle characteristics of these alloys are their excellent response to precipitation-hardening treatments, excellent thermal conductivity, and resistance to stress relaxation.
