Carbon steel and alloy steel nuts for elevating fastening solutions
When it comes to high-pressure and high-temperature environments, precision and durability are paramount. Enter ASTM A194, the standard encompassing carbon, alloy, and stainless steel nuts designed to excel in demanding conditions. Let’s delve into the specifications and applications of these nuts:
Bolts and nuts with Teflon coating
ASTM A194 Overview:
Nominal Size Considerations: For nuts with nominal sizes equal to or less than 1 inch, UNC series 2B fit is recommended. For nuts exceeding 1 inch in nominal size, UNC series 2B fit or 8UN series 2B fit is advised. Among these, the ASTM A194 Grade 2H high-strength nuts stand out as a common choice in the market.
Variants and Applications:
ASTM A194 Grade 2: Suitable for high-temperature and high-pressure environments.
ASTM A194 Grade 2H: Designed for high-temperature and high-pressure environments, often subjected to quenching and tempering treatments.
ASTM A194 Grade 2HM: Similar to Grade 2H nuts but recommended for use in corrosive environments.
ASTM A194 Grade 4: Heat-treated molybdenum steel nuts, ideal for extreme temperature and pressure conditions.
ASTM A194 Grade 7: Heat-treated chromium-molybdenum steel nuts, suitable for extreme temperature and pressure conditions. Also applicable in low-temperature environments, meeting minimum Charpy impact requirements as per ASTM standards.
ASTM A194 Grade 7L: Heat-treated chromium-molybdenum steel nuts, designed for extreme temperature and pressure conditions. Recommended for use in low-temperature environments, meeting minimum Charpy impact requirements as per ASTM standards.
ASTM A194 Grade 7M: Similar to Grade 7L nuts, recommended for use in corrosive environments.
ASTM A194 Grade 8/8M: Stainless steel nuts, recommended for use in corrosive environments.
Each variant within the ASTM A194 standard is meticulously engineered to meet specific performance requirements, ensuring reliability and longevity in critical applications. From high-strength nuts capable of withstanding intense pressures to corrosion-resistant options tailored for challenging environments, ASTM A194 nuts provide versatile solutions for diverse industrial needs.
