摘要:

根据化肥厂中不锈钢水冷器损坏情况,分析了导致不锈钢水冷器应力腐蚀开裂的诸因素,指出循环冷却水中氯离子的含量并不是应力腐蚀开裂的决定性因素,水冷器的出水温度是重要因素。

关键词: 不锈钢, 循环冷却水, 腐蚀开裂

Abstract:

Based on the damages of stainless water coolers in chemical fertilizer plants, the influential factors of the stress corrosion cracks are analyzed. The effluent water temperature of the water cooler is an important factor.

Key words: stainless steel, circulating cooling water, corrosion cracks
