PH13-8Mo钢在3.5%NaCl水溶液中应力腐蚀性能研究

STRESS CORROSION CRACKING OF PH13-8 Mo STEEL IN 3.5% NaCl AQUEOUS SOLUTION

研究了PH13 8Mo钢在 3 .5 %NaCl水溶液中的应力腐蚀敏感性。研究表明 ,PH13 8Mo钢具有较好的抗应力腐蚀性能 ,其应力腐蚀断口形貌为穿晶型 。

The sensitivity of PH13-8Mo steel to stress corrosion cracking (SCC) in 3.5%NaCl aqueous solution was studied. The results indicated that the steel was relatively resistant to SCC. The cracking mode was transgranular cracking with secondary cracks.
