The Asme SA194 Grade 8m's improved mechanical features are just a few advantages. For instance, the ASTM A194 Grade 8m Class 2 Nuts are renowned for their low maintenance requirements, rigid construction, long lifespan, and ease of use. Products made from A194 Gr 8m Material must adhere to strict requirements that prevent radioactive and mercury contamination.
Table of Content
The ASTM A194 Grade 8m Nuts have a Brinell hardness value of 223 BHN, a yield strength of 240 Mpa, elongation in 4D of 30%, reduction of 40%, and a tensile strength of approximately 550 Mpa. The A194 Grade 8m Nuts are utilised in various industries because of their strong performance and good mechanical and physical qualities.
For instance, SA194 Grade 8m Standard Fasteners are used in sea water equipment, power generation, gas processing, petrochemicals, specialty chemicals, and burner pipes and flues in aircraft exhaust fastenersonline, offshore oil drilling companies, and power generation. The SA 194 Gr 8m Fasteners are employed in applications for heat exchangers, pharmaceuticals, and pharmaceutical equipment.
