Are you interested in the sheet, Haynes 188® alloy tape (2.4683, Alloy 188) from the supplier — AvecGlob company? Here you will find the necessary information on this topic

Company Avecglobal sells sheet metal (sheet, tape) made of Haynes 188® alloy (at an affordable price, other names — 2.4683, Alloy 188) at an affordable price. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Composition and application

Haynes 188® (2.4683, Alloy 188) is an alloy with an increased content of cobalt, nickel, chromium and tungsten. Alloys of cobalt have an inherent advantage over the classes of nickel base at high-temperature creep.

Haynes 188® is also distinguished by its high resistance to sulfur-containing atmospheres, as well as its long-term resistance to oxidation, which is completely preserved up to temperatures of 1095 ° C. Haynes® Alloy 188 is not a hardenable alloy, but it can be subjected to cold plastic deformation to achieve higher tensile strength and higher yield strength. The alloy is characterized by good deformability in the cold state.

The main areas of use of this alloy are the production of lubricating stations and devices, guides for heating equipment, plafonds, gas turbine rotors and diaphragm valve nozzles.

Fields of application Haynes 188® (2.4683, Alloy 188) — military and commercial aerospace industry, processing of reactive media, surface gas turbines and nuclear equipment.

The chemical composition of the alloy meeting the technical requirements of the UNS R30188 standard is presented in the table:

Element Cr Ni Co W La B C Fe Mn Si P S
Minimum percentage 20.0 20.0 - 13.0 0.02 - 0.05 - - 0.2 - -
