STAINLESS STEEL 321 & 321 H BOLT is austenitic stainless steel. Titanium, on the other hand, helps to stabilize this stainless steel. The titanium component makes it more resistant to oxidation and corrosion. It can withstand temperatures of up to 1500 degrees Fahrenheit. Carbide precipitation is likely to occur at these high temperatures, but the inclusion of titanium prevents it.
The STAINLESS STEEL 321 & 321 H BOLT cannot be hardened sufficiently by heating, but it can be done by cold working. This also provides excellent welding capabilities. They are also very ductile and simple to fabricate. It can withstand harsh environments, but it is not suitable for chlorine-bound environments.
STAINLESS STEEL 321 & 321 H BOLT has high tensile strength and can withstand harsh environments such as aqueous environments. These bolts are widely used in applications requiring high strength because they can carry the weight while also preventing corrosion pitting and cracking.
The main distinction between 321 and 321 H stainless steel bolts is the amount of carbon in them. The carbon content of 321 bolts is approximately 0.08 percent, while the carbon content of 321 H is approximately 0.04 percent to 0.10 percent. Other elements such as manganese, silicon, phosphorus, sulfur, chromium, and nitrogen are also present.
