![]() 304L 30403 1.4307 Good at general corrosion resistance to acidic as well as caustic material with low carbon and improved performance. Commonly known names UNS ENĪttributes 304 S30400 1.4301 Good at general corrosion resistance to acidic as well as caustic material. What are the most commonly used stainless steel for pharmaceutical industry and its attributes. Step 5.3: Drop develops red color and remains for a longer time for SS 316 Step 5.2: Drop develops red color and disappears immediately for SS 304 Step 5.1: Drop develops black color and remains as it is for SS 202 Step 5: Remove the battery after drop develops color Step 4: Place 9V current –ve pole of battery on electrolyte solution and touch another part on the stainless steel part Step 3: Put one drop of electrolyte solution on the test metal Step 2: Ensure that the test metal is clean, dry, and surface free from grease Molybdenum detection electrolyte kit, ii. The stepwise procedure of the Molybdenum Spot Test is described as follows: Molybdenum Spot Test procedure for identification of SS 202, SS 304, and SS 316 The Molybdenum Spot Test is a beneficial non-destructive method for quickly identifying Stainless Steel (SS) 202, SS 304, and SS 316. Using the stainless steel identifying by Molybdenum Spot Test, we can quickly identify the inferior quality of stainless steel. We cannot understand the difference in Stainless Steel grades based on the appearance, whether it is Stainless Steel (SS) 202, SS 304, or SS 316. Whereas SS 202 and SS 304 have comparative less corrosion resistance It is not reactive, additive, or absorptive hence, it will not alter the safety-identity-strength-quality-or-purity of the drug product and have more corrosion resistance. ![]() In the pharmaceutical industry, the majorly used grade of Stainless Steel is SS316 or SS 316L. 211.65 Equipment construction, it says that… When we refer to 21 CFR, PART 211, Subpart D – Equipment, Sec. The drug product should not have any additional component except defined in the approved formulation. The main reason behind the usage of this metal is that it is compatible with most manufacturing processes. Quick and easy identification of Stainless Steel SS 202, SS 304 and SS 316 using electrolyte detection of MolybdenumĪ non-destructive method for quick and reliable identification of SS (Stainless Steel)Įquipment used in the pharmaceutical industry are majorly made up of specific grades of Stainless Steel.
