Specific standards
Food grade stainless steel
Various containers and foods for storing food
The processing machinery shall be austenitic or ferritic stainless steel (1Cr18Ni9Ti, 0Cr19Ni9, 1Cr18Ni9, 1Cr17Ni2). Martensite stainless steel (0Cr13, 1Cr13, 2Cr13, 3Cr13) can also be selected for the abrasive tools and drilling tools for processing.
Specific physical and chemical indicators are as follows:
Project Austenitic stainless steel Ferritic martensitic stainless steel
Lead (calculated by Pb), mg/L in 4% acetic acid immersion solution ≤ 1.0 1.0.
Chromium (calculated by Cr), mg/L in 4% acetic acid immersion solution ≤ 0.5
Nickel (calculated by Ni), mg/L in 4% acetic acid immersion solution ≤ 3.0 1.0.
Cadmium (calculated by Cd), mg/L in 4% acetic acid solution ≤ 0.02 0.02.
Arsenic (as As), mg/L in 4% acetic acid solution ≤ 0.04 0.04.
Note: The soaking conditions are boiling for 30min and then room temperature for 24h.
