18-8: Used in products that require general atmospheric corrosion resistance, such as chemical and food-processing equipment. Some chemical environments may require special corrosion resistant materials and precautions. MATERIAL: 18-8: A cap screw made from one of the following austenitic alloys: 303, 303Se, 304, XM7, all of which are characterized as having a chromium content of 17-19% and nickel content of 8-10%. HEAT TREATMENT: The austenitic alloys develop their strength through work hardening during the fastener manufacturing process, as seen from the hardness properties below. The only heat treatment normally available on austenitic stainless alloys is annealing, which is done at approximately 1900°F to a dead soft condition and is not normally thermally reversible. HARDNESS: 1/4 through 5/8 in. diameter: Rockwell B95 - C32 | 3/4 through 1 in. diameter: Rockwell B80 - C32. YIELD STRENGTH: 1/4 through 5/8 in. diameter, 2.25D and longer: 65,000 psi. minimum | 3/4" (2.25D & longer) & 7/8 through 1 in. diameter (3D & longer): 45,000 psi. minimum. TENSILE STRENGTH: 1/4 through 5/8 in. diameter, 2.25D and longer: 100,000 - 150,000 psi. | 3/4" (2.25D & longer) & 7/8 through 1 in. diameter (3D & longer): 85,000 - 140,000 psi.
