具体标准

各种存放食品的容器和食品加工机械应选用奥氏体或铁素体型不锈钢(1Cr18Ni9Ti,0Cr19Ni9, 1Cr18Ni9,1Cr17Ni2)。对于加工部分的磨具钻具也可以选用马氏体型不锈钢( 0Cr13,1Cr13,2Cr13,3Cr13) 。食品级不锈钢

具体的理化指标如下:

项 目 奥氏体型不锈钢铁素体 马氏体型不锈钢

铅(以Pb计),mg/L 4%乙酸浸泡液中 ≤ 1.0 1.0 。

铬(以Cr计),mg/L 4%乙酸浸泡液中 ≤ 0.5

镍(以Ni计),mg/L 4%乙酸浸泡液中 ≤ 3.0 1.0 。

镉(以Cd计),mg/L 4%乙酸溶液中 ≤ 0.02 0.02 。

砷(以As计),mg/L 4%乙酸溶液中 ≤ 0.04 0.04 。

注:浸泡条件均为煮沸30min,再室温24h。
