High-Temperature ASTM A453 Grade 651 fine full thread stud bolt
STM A453 - Standard Specification for High-Temperature Bolting,
with Expansion Coefficients Comparable to Austentitic Stainless
Steels
This specification covers 5 grades of bolting with twelve classes
of yield strength ranging from 50 to 120 ksi [345 to 827 Mpa] for
used in high temperature service such as fasteners for pressure
bessel and valve flanges. The specification is expressed in both
inch-pound units and in SI units. BoltPort primarily stocks and
supply A453 Grade 660 Boltings for high temperature service. We
stock round bar in Grade 660, Grade 651 & Grade 665 for quick
manufacturing these bolts. These bolts are solution annealed and
age hardened to provide maximum efficiency in their applications.
We offer Rupture Test Facility for sufficient quantity order. ASTM
