ASTM A194 Grade 8CA specifies premium austenitic stainless steel nuts[cite: 1, 2]. These nuts are manufactured to exacting standards, ensuring high-quality performance in demanding environments. The material is formulated with a controlled chromium content of 17.00% to 19.00% and nickel content of 9.00% to 12.00% to provide excellent baseline corrosion resistance and structural stability[cite: 2].
To ensure optimal ductility and material integrity, Grade 8CA nuts are supplied in a Carbide Solution Treated condition[cite: 1, 2]. This specific heat treatment dissolves precipitated carbides, ensuring that the austenitic stainless steel maintains its corrosion resistance and meets strict mechanical requirements, such as a minimum hardness of 60 HRB[cite: 1, 2].
ASTM A194 Grade 8CA is a reliable standard for austenitic stainless steel fastening components[cite: 1, 2].
