Abstract

Abstract:

Influences of straightening process and thermal treatment on the tension properties of 690 alloy tube used in steam generators were investigated. The following influence rules have been revealed. Straightening can significantly increase the room temperature yield strength of the tube, but has little effect on tensile strength. Straightening pressure has a great influence on yield strength, while straightening speed has less impact. A higher straightening pressure makes a larger increment of yield strength. Tension property of the tube after straightening can be predicted according to the test results. The process of straightening has been shown to be stable.

Key words: 690 alloy heat exchange tube, straightening process, room temperature tension property, thermal treatment
