摘要
研究了建筑用不锈钢FV520B在35℃恒温条件下,在盐酸腐蚀介质(10wt%)和硫酸腐蚀介质(10wt%)中均匀浸泡腐蚀的耐腐蚀性。结果表明,FV520B钢在相同的腐蚀时间下,在盐酸腐蚀介质比硫酸腐蚀介质中的腐蚀程度更严重;在同等的腐蚀条件下,母材的腐蚀速率要比焊接接头的腐蚀速率大。
The corrosion resistance of FV520B steel, which were used in building, were studied in corrosive medium of hydrochloric acid（10wt%） and sulfuric acid（10wt%） at 35 ℃. The results show that the corrosion degree of FV520B steel in hydrochloric acid is more serious than that in sulfuric acid at the same corrosion time. The corrosion rate of parent metal is faster than welding joint under the same corrosion condition.
