XYLAN PTFE Coated ASTM A453 grade 660 Stud bolt
China manufacturer of XYLAN 1070 PTFE Coated ASTM A453 grade 660 Stud bolt
PTFE Coated ASTM A453 Grade 660 Stud Bolt Specification
ASTM A453 Grade 660 is a high-strength, heat-resistant, alloy steel that is commonly used for applications requiring high tensile strength at elevated temperatures. PTFE (Polytetrafluoroethylene) coating is often applied to these bolts to provide excellent corrosion resistance, chemical resistance, and non-stick properties.
ASTM A453-Grade 660 Stud Bolt is a low-carbon nickel-chromium-molybdenum-titanium-vanadium-boron alloy steel that is known for its excellent mechanical properties and resistance to corrosion. As a result, this material is used for the production of various critical components in high-temperature and high-pressure environments.
