| Abstract: | Hydrogen\|induced stress corrosion is one of the main failure modes for drill stem elements. It was examply stated that the macro and micro features of hydrogen\|induced stress corrosion and factors affecting on it for drill stem elements in hydrogen\|producing environment.The measures to prevent drill stem elements from hydrogen\|induced stress corrosion have been put forward. |
