Chanathip Nickel Alloys and Plates is a reliable manufacturer and supplier of Hastelloy Fasteners in Bangkok, Thailand. Our extensive range consists of bolts, screws, nuts, studs, and washers that can withstand rigorous corrosion and mechanical stress. These fasteners are produced with high-quality grades such as Hastelloy C276, C22, and B2 to provide dependability in severe chemical and marine environments. We produce fasteners as per international standards and provide custom sizes to meet various industrial requirements. Chanathip is renowned for precision production, punctuality, and technical know-how, making us the most wanted partner for specialty alloy fasteners in Thailand.
Hastelloy Fasteners are composed of nickel (56–60%), chromium (15–22%), molybdenum (13–16%), iron, cobalt, and tungsten, depending upon the grade. These alloys are highly resistant to a broad variety of acidic, oxidizing, and reducing environments. Mechanical properties are tensile strength of approximately 690 MPa, yield strength of 283–310 MPa, and elongation of 40–45%. Hastelloy fasteners retain mechanical strength in high-temperature and high-pressure conditions, offering superior corrosion fatigue and stress corrosion cracking resistance.
