A286 A453 GR660 bolts - LiuJi Power - Auto engine parts
The automotive engine components of Wuling Liuji Power. demand exceptionally high high-temperature resistance, stability, and elongation capabilities from their fasteners. Following a rigorous comparative analysis of bolts from various stainless steel fastener manufacturers, the A286 / 660A bolts demonstrated outstanding high-temperature performance, high stability, and superior tensile elongation.
1.4529 bolt Desulfurization in power plants
The 1.4529 Alloy 926 / 6Mo bolts and nuts exhibit exceptional resistance to pitting and crevice corrosion in halide-bearing media and sour, sulfur-containing acidic environments. Engineered to effectively resist chloride-induced stress corrosion cracking (SCC), these high-alloy fasteners maintain superior chemical stability and corrosion resistance across both oxidizing and reducing media. They are fully certified for pressure vessel manufacturing within a wide thermal operating range of -196°C to 400°C.
Duplex 2205 bolt - for mixing and agitation equipment
Tianhua Chemical Machinery & Automation Design Institute . is a premier, technology-driven enterprise under the China National Chemical Information Center (ChemChina).For the specialized industrial mixing and agitation equipment engineered , the performance requirements for stainless steel fasteners are extraordinarily stringent, demanding elite yield strength, robust impact toughness, and reliable localized corrosion fatigue resistance. Following intensive technical consultations and product evaluations, our Duplex 2205 fasteners were officially designated as the authorized stainless steel component solution for their industrial mixing assets.
The Duplex 2205 (UNS S32205 / S31803) bolts and nuts are manufactured from a premium duplex stainless steel alloy composed of 21% chromium, 2.5% molybdenum, and a 4.5% nickel-nitrogen matrix. This dual-phase microstructure delivers high mechanical strength, excellent impact toughness, and superior resistance to both general and localized stress corrosion cracking (SCC).
