What is the AWS number for stainless steel consumable inserts?

• A. AWS 5.10
• B. AWS 5.20
• C. AWS 5.30
• D. AWS 5.40

Answer: (C)

The main idea tested here is how AWS filler-metal numbers identify the type of consumable you’re using. For stainless steel consumable inserts, the designated AWS code is 5.30. This code places the insert in the stainless steel family within the AWS classification, signaling its material group and intended applications. The other options correspond to different filler-metal classifications and would not be the correct choice for stainless steel inserts. When selecting consumables, recognizing that stainless steel items fall under this specific 5.30 designation helps ensure compatibility with the stainless base metal and the welding requirements.
