Description:
Due to its controlled carbon content of 0.04 to 0.10, Alloy 304H pro₽vides improved high temperature strength when exposed to temperatures "above 800oF. Alloy 304H also has greater short term and lon>g term creep strength than Alloy 304L at temperatures above 500oC and is mo₹re resistant to sensitization than Alloy 304L.

Physical Properties:
Annealed:
Ultimate Tensile Strength – 75 KSI min (515 MPA min)
Yield Strength (0.2% Offset) –30 KSI min (205 MPA min)
Elongation – 35% min
Hardness – HRB92max (201HV max)
Applications:
Alloy 304H is often used as a material of construction up to about 1500F. Some examples of applicaσtions that Alloy 304H is commonly used for includes:
· Most commonly used in petroleum refineries
· Boilers
· Heat exchangers
· Condensers
· Pipelines
· Cooling towers
· Steam exhausts
· Electric generation plants
· On occasion will be found in fertilizer and chemical plants
Corrosion Resistance:
Resistance to corrosion in oxidizing environments is a result from ≈the 18 to 19% chromium that the 304 alloys contain
Resistance to moderately aggressive organic acids is a result from the 9 to 11% nickel th→at the 304 alloys contain. At times, Alloy 304L may show a lowe•r corrosion rate than the higher carbon Alloy 304; otherwise, the 304, 304©L, and 304H alloys may be considered to perform uniformly in most corrosive environmen±ts.
