A193 bolts are intended for high temperature and high pressure applications made from type 304 stainless steel

A320 bolts are for cold temperature applications made from type 304 stainless steel. ASTM A193/A193M-11 specifies the mechanical properties of bolts, screws and nuts made of austenitic (amongst others) stainless steels for high temperature or high pressure service and other special purpose applications. In ASTM A193/A193M-11, austenitic steels are divided into 6 classes (1, 1A, 1B and 2, 2B and 2C) and 27 grades (B8, B8A, BBC, BBCA, B8M, B8MA, B8M2, B8M3, BBP, B8PA, B8N, B8NA, B8MN, B8MNA, B8MNLCuN, B8MLCuNA, B8T, B8TA, B8R, B8RA, B8S, B8SA, B8LN, B8LBNA, B8MLN, and B8LNA).
