ASTM A453 Grade 660 Bolts
Manufacturer of ASME SA 453 gr 660 Stud Bolts, Grade 660 Class A Nuts in India
These have high Brinell hardness score ranging from 248 to 341HBW. The astm a453 grade 660 Nut Bolts range in size and length according to the grades. They range from 3/8 inches to 4 inches in sizes. The sizes range up to M100 in the metric system for the ASTM A453 Grade 660 Class D Studs. These are high tensile fasteners and can be used in high vibration systems such as engine parts. As these also can withstand high temperature and pressure, these are used in boiler, pressure vessel and pipeline applications. The ASTM A453 Gr 660 Class C Bolts are used in oil and gas lines as well. The rupture resistance of these bolts make them better for use in oil and gas transmission lines. The A453 Grade 660 Class B Stud Bolts can also be easily applied to applications that need frequent installation and uninstallation of the bolts for testing and operational needs. The ASTM A453 Gr 660 Stainless Steel Bolt can be heat treated to achieve the necessary hardness. The four different classes can be heat treated differently and are used in different application types. The class D A453 Gr 660 specification fastener is more expensive than the other classes. Regal Sales Corporation is a leading manufacturer and supplier of the different types such as the ASTM A453 Grade 660 Class A Nuts and other classes. As a leading supplier, we supply all different classes, types and variations of the fasteners. Please feel free to contact us for any product inquiry such as the ASTM A453 Gr.660 Cl.B or any pricing inquiries.
