Inconel 625 bar is a heat resistant nickel based superalloy. The high strength of these bars makes them a difficult prospect for machines. Bars of this grade have a machinability rating of 17% and a hardness of 29 HRC.
Compared to Alloy 718, Alloy 625 has higher corrosion resistance in high temperature environments.
Due to the solid solution effect of refractory metals, it has excellent toughness and strength in the temperature range from low temperature to 2000¡ãC (1093¡ãC). This Inconel grade can withstand stress cracking up to 1200¡ãC (649¡ãC) and is resistant to oxidation and oxidation up to 2000¡ãC.
Incoloy 800 was produced as early as the 1950s, but at that time, nickel was not widely used, so it was really only used in special cases when producing certain steels. This grade has high temperature strength and resistance to carburization, oxidation and other high temperature corrosion.
Incoloy Alloy 800H/800HT round bar has excellent resistance to carburizing, oxidation and nitriding. They are not prone to embrittlement even after extended operation at temperatures up to 12000F to 16000F.
DIN 1.4876 Rounds can work over a range of temperatures and pressures and exhibit excellent mechanical properties. These components have a minimum tensile strength of 600mpa and a minimum yield strength of 275mpa. ASTM B408 Incoloy 800 Precision Ground Rods are designed to have a uniform cross section. The strips are dimensionally and geometrically accurate.
Nickel 800 cold rolled bars run on the die shortly after the hot rolling process, allowing the bars to exhibit exceptional strength and excellent surface finish. Alloy 800 Bright Bar is an aesthetically appealing grade that can be produced in different finishes and sizes.
Like many other nickel alloys, it is ductile and easy to form and weld. This alloy is used in most industrial environments where corrosive chemical environments exist and other alloys fail.
Nimonic 80 a (Alloy 80A) is one of the most popular superalloys specified for gas turbines. Nimonic 80A fasteners are often specified because of their ability to withstand very high temperatures. This makes Nimonic bolts and nuts ideal for use in aircraft parts and custom-designed gas turbine components, from turbine blade mounting to exhaust nozzles on jet engines, where Nimonic fasteners are exposed to very high levels of pressure and heat.
Monel 400 is resistant to steam and sea water as well as highly corrosive solutions such as sulfuric, hydrochloric and hydrofluoric acids after degassing. It has excellent solderability and can withstand very high pressure and weight. The alloy has excellent mechanical properties at sub-zero temperatures, with a melting point of 2370¡ã – 2460¡ã F, and the product can be used at temperatures up to 1000¡ã C.
Alloy C-276 is one of the most versatile corrosion-resistant alloys available today.
Alloy C276 is a nickel, chromium and molybdenum alloy. Hastelloy C276 is designed for excellent corrosion and oxidation resistance in a variety of environments. These alloys also show resistance to pitting and crevice corrosion.
Carbon Steel ASTM A105 Flanges Made of carbon or mild steel material. Carbon, manganese, phosphorus, sulfur and iron may be included in the material composition.
304 is chromium-nickel austenitic stainless steel. Better corrosion resistance than Type 302. High ductility, excellent drawing, forming and spinning properties. Inherently non-magnetic, it becomes slightly magnetic when cold worked. Low carbon content means less precipitation of carbides in the heat affected zone during welding and less susceptibility to intergranular corrosion.
Hastelloy C-276 alloy has excellent resistance to a variety of chemical process environments, including strong oxidizing agents (such as ferric chloride and cupric chloride), hot fouling media (organic and inorganic), chlorine, formic and acetic acid, acetic anhydride, and Seawater and brine solutions.
It can be used in flue gas desulfurization systems due to its excellent resistance to sulfur compounds and chloride ions in most scrubbers.
Alloy C-276 has excellent resistance to pitting and stress corrosion cracking. It is also one of the few materials that can withstand the corrosive effects of wet chlorine, hypochlorite and chlorine dioxide.
The alloy is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.
HASTELLOY(r) C276 can be formed by cold working using conventional techniques.
HASTELLOY(r) C276 is solution heat treated at 1121¡ãC (2050¡ãF) and then rapidly quenched. In the case of forging or hot forming, parts should be solution heat treated prior to use.
Welding of this alloy is similar to that of the C-22 alloy. Gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW) are commonly used to weld C-276 alloys.
It is recommended that the alloy be welded in the solution annealed condition with C-276 filler metal.
Austenitic stainless steels are susceptible to stress corrosion cracking (SCC) in halide environments. Although type 316 alloys are more resistant to SCC than 18Cr-8 Ni alloys due to their molybdenum content, they are still susceptible. Conditions that produce SCC are: (1) the presence of halide ions (usually chloride ions), (2) residual tensile stress, and (3) temperatures in excess of about 120¡ãF (49¡ãC).
Fully austenitic welds are more prone to cracking during welding. For this reason, Type 316 and Type 316L “matching” filler metals are formulated to cure with a small amount of ferrite in the microstructure to minimize cracking susceptibility.
Unlike other types of steel such as 304 and 306, the 316l stainless steel alloy can be used in a variety of applications where high corrosion resistance is required. For example, specialists in the chemical and pharmaceutical industries use it to make surgical tools and medical implants.
