Principal Design Features
C-276 is a wrought corrosion-resistant alloy. A prime advantage of this alloy is that it generally does not require solution heat treatment after welding. It resists the formation of grain boundary precipitates that would degrade corrosion resistance.
Types
HASTELLOY C276
HASTELLOY C-276 alloy is a nickel-molybdenum-chromium wrought alloy that is generally considered a versatile corrosion-resistance alloy. HASTELLOY C-276 alloy has excellent resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, and seawater and brine solutions. It is used in flue gas desulfurization systems because of its excellent resistance to sulfur compounds and chloride ions encounted in most scrubbers.
HASTELLOY C22
The C-22 alloy exhibits superior weldability and is used as overalloy filler wire and weld overlay consumables to improve resistance to corrosion C-22 alloy has exceptional resistance to a wide variety of chemical process environments including strong oxidizers such as ferric and cupric chlorides, chlorine, hot contaminated solutions (organic and inorganic), formic and acetic acids, acetic anhydride, and seawater and brine solutions
HASTELLOY C2000
The technical objective during the design of HASTELLOY C-2000 alloy* was even greater versatility, as compared with the traditional Ni-Cr-Mo alloys. This was accomplished by use of a high chromium content (23 wt.%), a high molybdenum content (16 wt.%), and a small but effective addition of copper (1.6 wt.%)

Duplex 2205 (S31803)
Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. At temperatures above 300°C, the brittle micro-constituents of this grade undergo precipitation, and at temperatures below -50°C the micro-constituents undergo ductile-to-brittle transition; hence this grade of stainless steel is not suitable for use at these temperatures.
Duplex S32750
Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.

Principal Design Features
This is the most commonly used and widely available grade of unalloyed titanium. The grade combines excellent corrosion resistance and weldability with good strength, ductility and formability. Beta Transus (F +/- 25) 1675.
Types
Titanium Gr.2
With moderate strength and excellent corrosion resistance and formability, Grade 2 titanium represents the most widely used form of titanium. Compared to the other grades of commercially pure titanium, Grade 2 titanium is slightly weaker than Grade 3, but stronger than Grade 1 and equally resistant to corrosion. These properties account for Grade 2 titanium's versatility in regard to its applications.
