Grade 8M is a bolt class manufactured from AISI 316 or equivalent stainless steel according to the ASTM A194 standard, offering high corrosion resistance. It provides long-lasting and reliable connections, particularly in environments containing chlorine, acids, and salts.
Grade 8 is manufactured from AISI 304 stainless steel; Grade 8M, providing higher corrosion resistance AISI 316 or 316L It is made of stainless steel. Therefore, Grade 8M is more resistant in seawater, chemical substances, or acidic environments.
It is used in areas with aggressive conditions such as high temperature, high humidity, salt water, or chemical vapors, particularly in the food, pharmaceutical, chemical, marine, and energy industries. A longer service life can be achieved with special coatings such as PTFE or Geomet.
