astm a193 b8 class 2 is a standard material specification for austentic stainless steel corrosion resistant fastener which is used for high temperature and high temperature and for special application purpose such as pressure vessels bolting and pressure piping. astm a193 grade b8 class 2 has a higher tensile and yield strength than other steel grades such as astm a193 grade b5 and astm a193 grade b7.

b8 class 2 bolts is a high-strength bolts are typically used in standard temperature and pressure level applications such as general-use construction projects. a193 b8 class 2 is a strain hardened and carbide solution treated stainless steel 304. It has a minimum tensile strength of 125ksi and yield strength of 100ksi and maximum hardness of 35 HRC.  b8 class 2 is also quenched and tempered at 800 F leading to its strength. It has carbon of 0.28-0.55%, phosphorus of 0.030% max and sulfur of 0.050% max.

a193 b8 cl2 is an automotive specification. Both specifications are heat treated and tempered at 800° F, which creates a very strong part but increases brittleness more than comparative specifications. sa193 b8 cl2 is typically used for threaded bolts in demanding applications such as automotive suspensions for large trucks and tractors.
