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.
Nickel 201 is the low-carbon version of Nickel 200. Because of its low carbon content, Nickel 201 is not subject to embrittlement by intergranularly precipitated carbon or graphite when exposed to temperatures of 315 to 760℃ for prolonged time if carbonaceous materials are not in contact with it. Therefore, it is a substitute for Nickel 200 in Applications above 315℃.
