Advantages of Commercially Pure Titanium and Titanium Alloy- SCALE STEEL.

​1. Good Corrosion Resistance- The corrosion [SCALE STEEL]resistance of titanium alloy is much better than that of stainless steel when working in humid atmosphere and seawater medium.  Resistance to pitting corrosion, acid corrosion, stress corrosion is particularly strong;  Excellent corrosion resistance to alkali, chloride, chlorine organic articles, nitric acid, sulfuric acid and so on.  But titanium has poor corrosion resistance to reducing oxygen and chromite medium.  
 
2. Low Temperature Performance is Good- Titanium alloy can keep its mechanical properties at low temperature and ultra low temperature.  Titanium alloys with good low temperature performance and very low clearance elements, [SCALE STEEL]such as TA7, can maintain certain plasticity at -253℃.  Therefore, titanium alloy is also an important low temperature structural material.  
 
3. Chemical Activity- Titanium has high chemical activity, and has strong chemical reaction with O, N, H, CO, CO2, water vapor and ammonia in the atmosphere.  When the carbon content is greater than 0.2%, hard TiC will be formed in titanium alloy.  When the temperature is higher, TiN hard surface layer can be formed by the interaction with N. Above 600℃, titanium absorbs oxygen to form a hard layer with high hardness.  When hydrogen content increases, embrittlement layer will also be formed.  [SCALE STEEL]The depth of hard brittle surface produced by gas absorption can reach 0.1 ~ 0.15mm, and the hardening degree is 20% ~ 30%.  Titanium chemical affinity is also large, easy to friction surface adhesion phenomenon.  
 
4. Small Thermal Conductivity Elasticity- The thermal conductivity of titanium λ=15.24W/ (m.K) is about 1/4 of nickel, 1/5 of iron, 1/14 of aluminum, and the thermal conductivity of various titanium alloys is about 50% lower than that of titanium. The elastic modulus of titanium alloy is about 1/2 of steel, so its rigidity is poor, easy deformation, should not make slender rod and thin wall parts, cutting the processing surface of the[SCALE STEEL] springback is very large, about 2 ~ 3 times of stainless steel, resulting in severe friction, adhesion, adhesion wear of the tool surface.
