Crafted to meet international standards, these bolts boast precise threading, exceptional mechanical strength, and accurate dimensions. The Stainless Steel 253 Ma alloy is a high-grade austenitic stainless steel, specifically designed for outstanding oxidation and corrosion resistance even at elevated temperatures. This makes it a fantastic choice for power plants, chemical processing, and the petrochemical sector. Malik Fasteners guarantees that these bolts provide dependable, long-lasting fastening solutions that uphold structural integrity, endure thermal cycling, and consistently perform in challenging industrial and marine environments.
Stainless Steel 253 Ma Bolts are mainly made up of chromium (22%), nickel (11%), molybdenum (0.7–1.0%), and nitrogen for added strength, with iron making up the rest. They showcase impressive tensile and yield strength, along with excellent hardness, toughness, and resistance to creep, thermal fatigue, and oxidation at high temperatures. Thanks to their austenitic microstructure, these bolts offer remarkable corrosion resistance in both oxidizing and reducing conditions, while also maintaining good ductility and dimensional stability. These mechanical and chemical traits make 253 Ma Bolts perfect for critical high-temperature applications that demand long-term reliability, mechanical integrity, and resilience against harsh industrial or marine environments.
