Alloy 200 contains nickel as well as molybdenum, copper, chromium and various other elements. This chemistry provides unique properties and strength to operate efficiently in high temperature applications. It has excellent resistance to oxidation and corrosive environments.
One of the significant advantages of coiled tubing over straight tubing is that it can be handled in extra-long lengths, largely due to its shape allowing for long stretches on export without the constraints of traditional container length limitations. This extra length can be extended theoretically indefinitely, as far as welding conditions allow, thus meeting the requirement for extra-long seamless connections for specific engineering needs.
Alloy 625 tubing is suitable for use in the oil and gas industry, chemical processing equipment, and marine applications, especially those requiring high temperature, corrosion resistance, and high strength.
Alloy 400 has excellent resistance to corrosion by many reducing media such as sulfuric and hydrochloric acids. It is generally more resistant to corrosion by oxidizing media than higher copper alloys. Alloy 400 resists pitting and stress corrosion cracking in most fresh and industrial waters.
Alloy 825 has excellent resistance to chloride-ion-induced stress corrosion cracking, reducing environments containing phosphoric and sulfuric acids, oxidizing environments containing nitric acid and nitrates, and pitting, crevice corrosion and intergranular corrosion
Alloy 625 has excellent strength at temperatures up to 816℃. At higher temperatures, its strength is generally lower than that of other solid solution strengthened alloys.
Alloy 601 has good resistance to heat and corrosion, especially outstanding to oxidation at elevated temperatures up to 1200℃. It also has high strength, good fabricability and good resistance to aqueous corrosion.
UNS N08800 has good rupture and creep strength and excellent resistance to oxidation, carburization and sulfidation at temperatures up to 816℃. It also resists general corrosion by many aqueous media. For Applications requiring higher stress rupture and creep properties, especially at temperatures above 816℃, UNS N08810 and UNS N08811 are recommended. UNS N08800 is readily formed, welded and machined.
Alloy K500 / UNS N05500 combines Alloy 400’s excellent corrosion resistance with greater strength and hardness as a result of adding aluminum and titanium and proper heat treatment to cause precipitation hardening.
Through more than ten years of research and development, the production of MTSCO Alloy technology and efficiency of various materials have been greatly improved. The enterprise has passed the national quality management system certification of weapons and equipment, obtained more than 24 authorized patents, participated in the revision of 9 national standards and 3 industry standards.
Alloy B has excellent resistance to reducing environments like sulfuric acid at moderate concentrations and other nonoxidizing acids. It also resists stress corrosion cracking induced by chlorides.
Alloy 718 is an age-hardenable nickel-chromium alloy that combines corrosion resistance with high strength and good fabricability. It has high creep-rupture strength at temperatures up to 700℃. Its excellent relaxation resistance contributes to its application in springs.
