Stainless Steel 321H Bolts comprise metal alloys containing at least 10% chromium content. The contents of chromium and nickel are the two elements that give these fasteners more resistance to corrosion compared with other grades of alloys. The designation "H" stands for "High." It means high carbon content, and it is what makes the bolts stronger and resistant to wear impacts found in other bolting grades. It is the higher carbon content that lends improved mechanical properties that allow bolts to sustain heavy loads under heinous conditions.

The main benefit of using Grade 321H Stainless Steel Bolts is that they exhibit excellent resistance to corrosion. It's because the content level of chromium and nickel in these bolts is high enough to withstand rusting in damp conditions, saltwater, and other liquids and substances that cause corrosion. This makes the bolts quite useful for applications in marine environments and those that require a great deal of resistance against corrosion. Moreover, high values of tensile strength and ductility for such fasteners guarantee that they will safely tolerate large loads without breaking and easily deforming.
