Product DescriptionHigh Temperature and Corrosion Resistant X6NiCrTiMoVB25-15-2 Stud Bolt, AISI 660 Alloy Steel FastenerHigh Temperature & Corrosion-Resistant X6NiCrTiMoVB25-15-2 Stud Bolt (AISI 660 Alloy Steel) Crafted from premium AISI 660 nickel-chromium superalloy, this stud bolt excels in extreme environments. It offers exceptional thermal stability (-253°C to 700°C), corrosion resistance to aggressive media, and robust performance (≥1400MPa tensile strength, creep/fatigue resistance). Compliant with ASME B18.31.2M/ISO 898-6, it suits mission-critical uses in power generation, chemical, aerospace, and offshore oil & gas for reliable harsh-condition operation.SpecificationKey FeaturesExceptional High-Temperature Strength: Maintains tensile and creep strength at temperatures up to 700°C (1292°F), ensuring structural integrity in extreme heat.Superior Corrosion Resistance: Resists oxidation, carburization, and corrosion from aggressive chemicals (acids, salts, molten metals), extending service life in harsh media.Outstanding Fatigue & Creep Resistance: Withstands cyclic loading and long-term static loads at high temperatures without deformation or failure.Excellent Thermal Stability: Low coefficient of thermal expansion minimizes thermal stress in temperature-fluctuating applications.Compliance with Industry Standards: Manufactured to meet or exceed international standards for alloy steel fasteners, guaranteeing reliability in critical uses.Applications Aerospace Industry: Jet engine turbine sections, exhaust system fastenings, and aircraft structural components exposed to high temperatures.Power Generation: Gas turbine combustion chambers, nuclear power plant pressure vessels, and reactor internals requiring radiation and corrosion resistance.Chemical & Petrochemical Industry: Refinery catalytic crackers, heat exchangers, and chemical reactors handling corrosive media (acids, alkalis, organic solvents) at elevated temperatures.Oil & Gas Industry: Downhole drilling tools, offshore platform equipment, and subsea connectors operating under high pressure and corrosive seawater conditions.Automotive Industry: High-performance racing engine parts and exhaust manifolds subject to extreme heat and mechanical stress.Medical Equipment: Sterilization systems and diagnostic device components requiring biocompatibility and high-temperature corrosion resistance.Specification ItemDetailsMaterialX6NiCrTiMoVB25-15-2 (AISI 660 Alloy Steel / Equivalent Superalloy)Alloy Composition (Typical)Ni: 50-55%, Cr: 14-17%, Fe: Balance, Ti: 2.25-2.75%, Al: 0.7-1.2%, Mo: 2.5-3.5%, V: 0.7-1.2%, B: ≤0.01%Thread StandardMetric (M8 – M64), UN/UNC/UNF (1/4" – 2")Length Range20mm – 500mm (Custom lengths available)Thread Tolerance6g (External Thread) / 6H (Internal Thread, if applicable)Tensile Strength≥ 1400 MPaYield Strength≥ 1200 MPaElongation≥ 15%Hardness38–42 HRC (Rockwell C Scale)Operating Temperature-253°C to 700°C (-423°F to 1292°F)Surface TreatmentPassivation, Electropolishing, PTFE Coating (Custom options available)Manufacturing StandardASME B18.31.2M, DIN 975, ISO 898-6 (Custom standards available)Quality AssuranceOur manufacturing process is strictly controlled, and each batch of bolts undergoes rigorous testing.Testing Certificates: We can provide Mill Test Certificates (MTC) or Material Test Reports (MTR) that comply with EN.10204.3.1. standards upon request.Quality Control: Procedures include dimensional checks, mechanical property testing (tensile, hardness), and surface inspection to ensure full compliance with specified standards.After Sales ServiceQuality Commitment: We stand behind our products with a warranty that covers any defects in materials and workmanship.Expert Support: Our technical team provides dedicated support to help you select the ideal bolts and nuts for your application.Efficient Service: We prioritize prompt responses and keep you updated throughout the entire process.Company ProfileXiamen Qishine Industry Co., Ltd.Xiamen Qishine Industry Co., Ltd., established in 2013, is a trusted supplier of industrial piping components.
