3. The largest of the three common stainless steel groups, and the type most often encountered by welders, is the

A. austenitic group
B. ferritic group
C. martensitic group
D. chromium-martensitic group



Answer :

Final answer:

The largest stainless steel group encountered by welders is the austenitic group, known for its non-magnetic properties and high corrosion resistance.


Explanation:

The largest of the three common stainless steel groups encountered by welders is the austenitic group. Austenitic stainless steels are non-magnetic and have high corrosion resistance, making them suitable for various applications such as kitchen equipment and piping.

These steels contain high levels of chromium and nickel, which provide their corrosion-resistant properties. An example of an austenitic stainless steel is 304 stainless steel, which is commonly used in household appliances and industrial equipment.
