Varestraint Test for Hot Crack Susceptibility of Chromium-Molybdenum Low Alloy Steels
スポンサーリンク
概要
- 論文の詳細を見る
The Trans-Varestraint Cracking test was done with 1.25Cr-0.5Mo, 2.25Cr-1Mo, 3Cr-1Mo and 5Cr-0.5Mo low alloy steels whose carbon was varied from 0.05 to 0.2% and impurities as sulphur and phosphor were less than 0.01%. As a result, the susceptibility to the solidification cracking was increased with an increase of chromium alloying element and a decrease of carbon content. Therefore, it is predicted that special attention for the solidification cracking should be paid for the welding of low carbon 5Cr-0.5Mo and 3Cr-1Mo steels.
