Product origin:

BaoTi group

Executive standard:

Plate: AMS 4911h, mil-t-9046j, ASTM b265, ASME sb265, dms1592f, gb/t 3621

Main ingredients:

Titanium (TI) residue, nitrogen (n) ≤ 0.05, carbon (c) ≤ 0.08, hydrogen (H) ≤ 0.015, iron (FE) ≤ 0.40, oxygen (o) ≤ 0.20, aluminum (AL) (5.5-6.75), vanadium (V) 3.5-4.5

Physical properties:

1. Small deformation coefficient: This is a remarkable feature of TC4 titanium alloy machining, and the deformation coefficient is less than or close to 1. The sliding friction distance of chips on the rake face is greatly increased, which accelerates tool wear. 2. High cutting temperature: because the thermal conductivity of titanium alloy is very small (only equivalent to 1/5 ~ 1/7 of No. 45 steel), the contact length between chip and rake face is very short, and the heat generated during cutting is not easy to be transmitted, which is concentrated in a small range near the cutting area and cutting edge, and the cutting temperature is very high. Under the same cutting conditions, the cutting temperature can be more than twice as high as when cutting 45 steel. 3. The cutting force per unit area is large: the main cutting force is about 20% smaller than that when cutting steel. Due to the extremely short contact length between the chip and the rake face, the cutting force per unit contact area is greatly increased, which is easy to cause edge collapse. four

Mechanical properties:

Tensile strength: σ B ≥ 895mpa, yield strength σ b≥828Mpa σ： Elongation: δ ≥10%。

Corrosion resistance:

Although titanium alloys are very active, have low equilibrium potential and have a great tendency of thermodynamic corrosion in media, they are actually very stable in many media, such as oxidizing, neutral and weak reducing media. This is because titanium has a great affinity with oxygen. In air or oxygen-containing medium, a dense, adhesive and inert oxide film is formed on the surface of titanium, which protects the titanium matrix from corrosion. Even due to mechanical wear, it will soon self heal or regenerate.
