NiMo28 alloy steel is a nickel-chromium-molybdenum Hastelloy alloy with good high-temperature stability. NiMo28 alloy steel is an Hastelloy grade, that resists the formation of grain-boundary precipitates in weld heat-affected zones. NiMo28 alloy steel also has excellent resistance to stress-corrosion cracking and to oxidizing atmospheres. NiMo28 alloy steel is also used in a varity of chemical process environments.

NiMo28 alloy steel Heat Treatment :
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
NiMo28 alloy steel Characteristic :
1.control iron and chromium in the lowest content, prevent the generation of β phase Ni4Mo
2.The excellent corrosion resistance to reduction environment.Sulfuric acid anti medium concentration
3 excellent non oxidative acid corrosion
4.very good resistance to chloride ion reduction to stress corrosion cracking (SCC)
5.Capacity of excellent resistance to various organic acid corrosion
