SY/T 7390-2017Age-hardened nickel-based alloys for oil and gas drilling and production equipment (English PDF)

SY/T 7390-2017 is the English-translated version of 石油天然气钻采设备时效硬化镍基合金.

SY/T 7390-2017 — This standard specifies the technical requirements for age-hardening nickel-based alloys for drilling and oil production equipment in the oil and gas industry, and supplements the existing provisions in GB/T 22513 to meet the requirements of GB/T 22513 pressure-bearing parts and pressure-control parts.

The age hardening nickel-based alloy does not suffer from material embrittlement due to excessive harmful phases, thereby ensuring that the minimum requirements for metallurgical quality are met. This standard does not apply to nickel-based materials for downhole equipment.
