Characteristics of Titanium (JIS H4650 Pure Titanium Class 2)
· Strength of titanium is comparable to low-carbon steel, yet the specific gravity is 60% of steel.
· It can be used in low to high temperatures.
· It has better chemical resistance than that of stainless steel.

■Typical Physical Properties of Titanium

Item	Unit	Data
Purity	%	99.5 or More
Tensile Strength	N/mm2	340~510
Yield Stress	N/mm2	215 or More
Operating Temp.	°C	-200~350

■Chemical Resistance of Titanium

Chemical Solution	Concentration (%)	Temperature (°C)	Titanium	EN 1.4401 Equiv.
Hydrochloric Acid	10	30	◎	×
Sulfuric Acid	20	30	○	×
Sodium Hydroxide	50	120	◎	○

◎: Corrosion resistant enough for use.
○: Corrosive but usable depending on conditions.
×: Unusable due to insufficient corrosion resistance.
