ASTM A286 Grade 660 Bolt
Trusted Manufacturer of UNS S66286 Hex Bolt in India, At Resonable Cost
ASTM A286 Stainless Steel Fasteners element contain an age hardenable iron base austenitic stainless steel. The material also increases its hardness with service time. The material that is used is carbon, manganese, silicon, molybdenum, iron, titanium, vanadium, aluminum, boron and Chromium 13% Nickel 24%. The ASTM A286 Grade 660 Bolts are produced as per the American metals standard and are of high strength.
The material has 620MPa minimum tensile strength and 275MPa minimum yield strength. The elongation rate at room temperature is 40%. The ASME SA 194 specification is also possible for these fasteners with different standards available such as the ASTM, ASME, DIN and ANSI. The A286 Screws range from M1.6 to M12 for machine screws and from M3 to M56 for other screws. The sizes are equivalent to 3/6 inches to 2 inches in the imperial system. The A286 Socket Head Cap Screw is one type of the fasteners which is used with a cap on it where there are different types such as hex screws, machine screws, wing screws and others.
The length of the fasteners range from 3mm to 200mm and the sizes range accordingly for different types. The a286 stainless steel bolts are stronger and are used in high tensile applications. The material can withstand high pressure and temperatures as well. The thread of fasteners can be either external coarse thread or internal fine thread. The Alloy A286 Stainless Steel Nuts And Bolts are applied to heat exchanges, boilers, condenser, generation of power plant, oil and the formation of gas well, petroleum and in the region of corrosion in general.
