Overview
GH903 is a kind of high temperature alloy. Its basic components include nickel, iron and cobalt, which are strengthened by precipitation of titanium, niobium and aluminum. The alloy has a low thermal expansion coefficient and an almost constant elastic modulus over a wide temperature range. GH903 alloy has high strength, good thermal fatigue performance, excellent welding performance and high pressure hydrogen embrittlement resistance. It is suitable for manufacturing turbine casing, sealing ring and other components of aviation and aerospace engines working below 650 °C. It is one of the important materials to realize engine clearance control technology. The main products provided by the alloy include bars and ring parts.

GH903 High hardness stainless steel with localized corrosion resistance Physical properties : Excellent
Mechanical properties of GH903 : 597 MPa ( small value of mechanical properties tested at 83 degrees )
The processing equipment is susceptible to corrosive environments and loading cycles, and the characteristics of GH903 are very suitable for such applications.
GH903 has excellent corrosion resistance in chloride, low concentration NaOH aqueous solution and high pressure water.
GH903 ( hardened alloy ) : martensitic stainless steel with many uses. Because of containing Ni, it is more tolerant than Cr heat-resistant stainless steel, and has low temperature strength. Therefore, the high elongation ability is very good, and the carbonization resistance is very large. Heat treatment is not hardened, non-magnetic, good strength, less elastic, and often uses a thickness of 6.7T ~ 1.8T.
Its overall tensile properties are better than GH903 in most media.
In various industrial applications in acidic media, especially in acid containing halides, GH903 is far superior to other non-bulging steels, and in some cases can be comparable to soft magnetic alloys and titanium.
GH903 cobalt-based alloy also has good carburization resistance in other chemical media, as well as high temperature tensile and rust resistance media, including sulfuric acid, phosphoric acid, acid gas, seawater, salt and organic acid.
Delivery status of GH903 duplex stainless steel : Generally delivered in a heat treatment state, and the type of heat treatment is indicated in the contract.
Urea precipitation hardening alloy GH903 is an austenitic stainless steel specially developed for urea production, which limits the relatively low content of Cr, Ni and Mo.
GH903 invar steel has strong crevice corrosion resistance. Inconel800 electrothermal alloy is used in petrochemical industry, electromechanical hardware, ship and power plant.
Due to the different ( Al + Ti ) content of the three, the environment in which the three super stainless steels are used is different. The specific performance is as follows : GH903 will exert various properties at subzero, room temperature and high elongation of 984 degrees.
GH903 precision alloy with SCC resistance is a chromium-nickel alloy with high temperature tensile properties of Japanese JIS standard seawater resistance series.
