ASTM A307 A193 A574 A276 A105 Bolt
ASTM A307 A193 A574 A276 A105 Bolt
ASTM A307 A193, A574, A276, and A105 are all different specifications for bolts used in various applications. Here is a brief overview of each:
1.ASTM A307: This specification covers carbon steel bolts and studs ranging from 1/4 inch to 4 inches in diameter. These bolts are typically used in general structural applications, such as building construction.
2.ASTM A193: This specification covers alloy steel and stainless steel bolts and studs for high-temperature or high-pressure service. The bolts are available in various grades, with each grade indicating the minimum tensile strength and other properties.
3.ASTM A574: This specification covers alloy steel socket-head cap screws, which are commonly used in machinery, especially in high-stress applications.
4.ASTM A276: This specification covers stainless steel bars and shapes used in a variety of applications, including bolts, screws, and other fasteners.
5.ASTM A105: This specification covers forged carbon steel piping components, including bolts, for use in pressure systems at ambient and high-temperature service conditions.
