Bolts are a kind of a fastening device used along with nuts to hold various materials together. Depending on the use of the device, these astm a276 bolts could be supplied in various conditions. For instance, these bolts could be supplied in condition A or what is known as annealing. Annealing bolts not only improves its ductility but also reduces its hardness, while also improving the electrical properties of the alloy. Astm a276 stainless steel bolts supplied in condition H must be tempered and hardened at a certain temperature.

The use of hardening and tempering aids in adjusting the ratio of hardness to toughness, which may be useful in applications. Often, the alloy of bolts is heated to an austenite forming temperature and following which the cooling gives it a martensitic microstructure. Cold worked or condition B ASTM A276 Grade Type 304L bolts are severely cold worked. And so the resultant bolt has better dimensional control in addition to an improved finish, with a reduction in contamination problems.

Under this specification, all the ASTM A276 Type 316 bolts are required to undergo a mechanical test. The mechanical test is used to confirm several properties of the ASTM A276 Type 403 including its tensile and yield strength, as well as elongation, and Brinell hardness.
