2507 is used for oil and gas industry equipment, offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, and injection and ballast water systems.
2507 is used for Chemical process industries, heat exchangers, vessels, and piping, desalination plants, high pressure RO-plant and seawater piping, mechanical and structural components, high strength, corrosion-resistant parts.
This type of steel is excellently resistant to shearing as a result of stress corrosion, high thermal conductivity and a low thermal expansion coefficient.
The high chromium, molybdenum, and nickel levels provide excellent resistance to pitting, crevice, and general corrosion.
Super Duplex stainless steel offers the same advantages as its Duplex counterpart. The main difference between the two is that Super Duplex has a higher chromium and molybdenum content, resulting in increased corrosion resistance.
It is widely used in offshore oil and gas exploration/production and in heat exchangers in petrochemical/chemical processing.
Super Duplex SAF 2507 is a really strong material with great corrosion resistance.
2507 has good weldability and workability, and it’s widely used in desalination equipment, chemical process pressure vessels, piping and heat exchangers.
Super Duplex 2507 has more than twice the strength of conventional austenitic stainless steels in the annealed condition. Type: Seamless, Welded WT: SCH5-SCH80S
S32750 is used for marine applications, flue gas scrubbing equipment, and pulp & paper mill equipment.
Super Duplex 2507 cannot be strengthened by heat treating. Annealing is performed at 1920¡ãF – 2060¡ãF (1049¡ãC – 1127¡ãC), followed by rapid cooling.
Alloy 600 is non-magnetic, has excellent mechanical properties and a combination of high strength and good workability and is readily weldable.
It is resistant to a wide range of corrosive media. The chromium content gives better resistance than Alloy 200 and 201 under oxidizing conditions, at the same time the high nickel gives good resistance to reducing conditions.
It is virtually immune to chlorine ion stress corrosion cracking. Demonstrates adequate resistance to organic acids such as acetic, formic and stearic. Excellent resistance to high purity water used in primary and secondary circuits of pressurized nuclear reactors.
It has little or no attack occurs at room and elevated temperatures in dry gases, such as chlorine or hydrogen chloride. At temperatures up to 550C in these media, this alloy has been shown to be one of the most resistant of the common alloys.
At elevated temperatures the annealed and solution annealed alloy shows good resistance to scaling and has high strength. The alloy also resists ammonia bearing atmospheres, as well as nitrogen and carburizing gases.
Under alternating oxidizing and reducing conditions the alloy may suffer from selective oxidation.
It is usually used in Thermocouple sheaths. Ethylene dichloride (EDC) cracking tubes.
Nickel Alloy 600, also sold under the brand name Inconel 600.
This alloy also displays good heat resistance and freedom from aging or stress corrosion throughout the annealed to heavily cold worked condition range.
Its high nickel content, a minimum of Ni 72%, combined with its chromium content, provides users of Nickel Alloy 600 a number of benefits such as good oxidation resistance at high temperatures and corrosion resistance to both organic and inorganic compounds.
The nickel content also provides excellent resistance to alkaline solutions.
Because of its versatility, and because it is the standard engineering material for applications which require resistance to corrosion and heat, a number of different critical industries use Nickel Alloy 600 in their applications. It is an superior choice for Nuclear reactor vessels and heat exchanger tubing and Chemical processing equipment. Alloy 600 can be provided in the lower strength, annealed condition, or strengthened through the pilger process.
Stress-relieving is performed after cold working to reduce residual stress and prevent distortion. Annealing is performed at 1700¡ãF – 1900¡ãF (927¡ãC – 1038¡ãC) to restore full softness.
Inconel 600 is a nickel-chromium alloy with good oxidation resistance at higher temperatures, with good resistance in carburizing and chloride containing environments.
Alloy 600 has good hot and cold workability in the annealed condition. Hot-working should be done above 1600¡ãF (871¡ãC) to ensure adequate ductility, while cold work should be performed below 1200¡ãF (649¡ãC).
The nickel content gives it excellent resistance to chloride-ion stress-corrosion cracking and also provides excellent resistance to alkaline solutions.
In strong oxidizing solutions like hot, concentrated nitric acid, 600 has poor resistance.
Alloy 625 has excellent weldability and is frequently used to weld AL-6XN? alloy. Matching filler metals are also used to join dissimilar metals.
Alloy 625 is a nickel-chromium alloy known and used for corrosion and oxidation resistance, and its high strength and fabricability.
