Description
CP Grade 2 Titanium ,TP270C, TP340C, TP340H, TB340
Commercially pure titanium grades feature an excellent strength-to-density ratio and good corrosion resistance. This makes them suitable for the manufacture of components in weight-saving structures with reduced mass forces, and also for components requiring high corrosion resistance. In addition, thermal stresses in titanium structures are lower than in other metallic materials, due to the low thermal expansion of titanium. The materials are also widely used in the medical sector because of their outstanding biocompatibility.
TP340, JIS Pure Titanium Plate, 340 ~ 510 MPa
TP340 is pure titanium.Titanium is over 99%
All other elements are metals that account for less than 1%.
Whether it is hot rolling or cold rolling,
According to the manufacturing rolling, it is TP340H for hot and TP340C for cold.
TP340 is pure titanium for industrial use
It has good corrosion resistance, especially sea water resistance
, and is used in chemical, petroleum, and pulp paper manufacturing equipment.
Titanium features
light weight — specific gravity of 4.51, approximately 60% of iron (Fe)
Strong — no difference in strength from steel and
biocompatible — extremely low ion elution, very low metal ion allergy
Corrosion resistance to seawater
— optimal for use in seawater environments due to seawater resistance to seawater and processability — equal to steel in processability
Non-magnetic — Non magnetic
low thermal expansion — thermal expansion coefficient of 8.40, equivalent to glass or concrete
Compared to Al: 23.9 and ordinary steel 11.6,
you can see how low it is.
※ Thermal expansion coefficient When the temperature (heat) rises by 1 ℃, it refers to the
ratio between the expanded size and the size before expansion. There are linear expansion coefficient and volume (volume) expansion coefficient.
The coefficient of thermal expansion decreases as the amount of carbon increases and the amount of alloy increases.
