P-T OPERATING GUIDELINES
|
 |
1- Usually satisfactory to use
without reference to Montero. Technical examination is normally
unnecessary.
2- Must refer to Montero for advice. A technical
examination is recommended
3- Area not recommended.
The P-T diagram helps the user or designer
who often knows the operating temperature and pressure to
carry out an initial selection of a suitable material . The
P-T diagram cannot guarantee the suitability of a material
for an application
