Machineability and Weldability

In its half-hard condition, 260 Brass has a machinability rating of 30 as compared to 360 brass rated at 100. 260 Brass has the highest ductility in the yellow brass series. Welding is not recommended, although 260 Brass has low to fair soldering and brazing capabilities. 260 Brass has poor butt-welding characteristics.

Material Overview

Characteristics: Monel is a high tensile strength nickel-copper alloy that was discovered in 1905. It was found to be highly resistant to atmospheric corrosion, salt water, and various acid and alkaline solutions. Alloy 400 can be magnetic depending upon composition and previous work history. Alloy K-500 has added aluminum and titanium for age hardening. It is totally nonmagnetic and spark resistant.

Uses: K-500 is used for gyroscope application and anchor cable aboard minesweepers. It is also used for propeller shafts on a wide variety of vessels and exhibits high fatigue strength in seawater. There is also application in chemical process applications for handling of organic acids, caustic and dry chlorine.

Monel 400 is used for marine engineering, chemical and hydrocarbon processing equipment, valves, pumps, shafts, fittings, fasteners, and heat exchangers.

Hastelloy® C-276

 

UNS Number N10276

Other common names: Alloy C276, Hastelloy C, Inconel® C-276

Hastelloy C276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high nickel and molybdenum contents make the nickel Steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition.

Although there are several variations of the Hastelloy nickel alloy, Hastelloy C-276 is by far the most widely used.

Alloy C-276 is widely used in the most severe environments such as chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and recovery of sour natural gas.

 

Corrosion Resistant Hastelloy C276

Considered one of the most versatile corrosion resistant alloys available, Hastelloy C-276 exhibits excellent resistance in a wide variety of chemical process environments including those with ferric and cupric chlorides, hot contaminated organic and inorganic media, chlorine, formic and acetic acids, acetic anhydride, seawater, brine and hypochlorite and chlorine dioxide solutions. In addition, alloy C-276 resists formation of grain boundary precipitates in the weld heat affected zone making it useful for most chemical processes in the as-welded condition. This alloy has excellent resistance to pitting and stress corrosion cracking.

 

What are the characteristics of Hastelloy C276?

  • Excellent corrosion resistance in reducing environments
  • Exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides
  • High nickel and molybdenum contents providing good corrosion resistance in reducing environments
  • Low carbon content which minimizes grain-boundary carbide precipitation during welding to maintain resistance to corrosion in heat-affected zones of welded joints
  • Resistance to localized corrosion such as pitting and stress-corrosion cracking
  • One of few materials to withstand the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide

History of Titanium

Originally named gregorite, after the British chemist, Reverend William Gregor who discovered it in 1791, titanium was independently discovered by the German chemist M.H. Klaproth in 1793. He named it Titanium after the Titans of Greek mythology; “the incarnation of natural strength.” In 1797 he discovered that his titanium was the same as Gregor’s newly found element. However, the element was not successfully isolated until 1910.

Titanium is the 22nd element on the periodic table. Its atomic weight is 47.867amu. It is a low density element (4510 kg/m3); approximately 60% less dense than that that of Steel. It is nonmagnetic, and transfers heat well. Its melting point (1993 K [3020 degrees F and 1650 degrees C]) is also higher than that of Steel. Titanium has high passivity; therefore it exhibits high levels of corrosion resistance to most mineral acids and chlorides. It is also nontoxic and biologically compatible with human tissue and bone, making it an ideal material for medical implant products.

Rutile and ilmenite, the 2 primary minerals which contain titanium, make up 24% of the earth’s crust, thus making titanium the ninth most abundant element on the planet. However, it occurs in nature only in chemical combinations; the most common of which are oxygen and iron.

Plain weave wire mesh is woven by alternating the shute wire over and under the warp wire, creating a wire mesh. 

Twill weave wire mesh is woven by passing the shute wire over and under two warp wires, creating a sturdier weave. This weave allows for the use of heavier wires, producing a stronger wire mesh.

Plain Dutch weave wire mesh is woven using two sizes of wire. Smaller wires, as small as micron size, are used in the shute direction and are woven with a larger warp wire. The smaller wires are woven tightly together, providing a tight mesh for filtering. The larger wire provides strength to the mesh.

Twill Dutch weave wire mesh combines Dutch and twill weaving to provide a fine mesh filtering cloth. Shute wires are passed over and under two warp wires, providing a tight, fine filter with tapered openings.
