Austenitic stainless steel grades 304 and 316 are two of the most popular SS Stud Bolt Materials utilised by Indian stainless steel stud bolt manufacturers. Due to the high concentration of chromium, molybdenum, and nickel in their alloy, both of these two kinds of stainless steel stud bolts have good mechanical characteristics. These three substances make up the majority of the alloying material in stainless steel stud bolts.
Table of Content
The stainless steel 304 stud bolts' ability to resist corrosion is comparable to that of stainless steel of the 316 grade. Chromium provides resistance to oxidation corrosion by forming a passivated oxide layer that self-heals in the presence of moisture and oxygen in the atmosphere in the alloy of both 304 and 316 SS Stud Bolts. The buyer can modify the carbon content of the Stud Bolts For Stainless Steel Flanges as needed. If the content is higher, the nomenclature will be changed to 316H for stainless steel with a high carbon content from 304L for stainless steel with a low carbon content.
Compared to the higher carbon variant of the stainless steel 304 stud bolts, the low carbon version exhibits improved intergranular corrosion resistance.
