Custom High-Temperature Bolts & Nuts for Steam Turbines
Our customized steam turbine high-temperature bolts and matching nuts are core heavy-duty fasteners for thermal power equipment, widely used on turbine main steam valves, high-pressure flanges, rotor shafts, cylinder split surfaces and bearing housings.
Product Overview
All products are tailor-made according to unit parameters, drawing specifications and actual working conditions. Manufactured from premium heat-resistant alloy steel via integral forging and ultra-precision CNC machining, they deliver stable clamping force under long-term ultra-high temperature & pressure, effectively resisting loosening, creep deformation and thread failure, avoiding steam leakage and unplanned unit shutdown.
Core Customization Advantages
Full Drawing Customization Support
Customizable thread specification, length, diameter, head shape, slot nut structure, undercut and chamfer
Supporting matching sets of bolts + slotted lock nuts, flat washers and spring washers
Compatible spare parts for all turbine retrofits
Flexible MOQ: Large batch for new power plant projects, small emergency batches for unit maintenance
High-Grade Heat-Resistant Alloy Materials
Material options matched to different temperature grades (540℃ ~ 620℃ ultra-supercritical units):
Material Grade
Application Range
35CrMoA, 42CrMo, 12Cr1MoV
Standard temperature applications
F91, F92, X12CrMoWVNbN
High temperature applications
17-4PH stainless steel
Corrosion resistance applications
High tensile strength, excellent anti-creep, anti-fatigue and oxidation resistance. Complete MTC material test certificates, chemical composition and mechanical performance reports provided for power plant acceptance.
Advanced Manufacturing Process
Integral open-die forging eliminates internal defects, optimizes metal grain flow, greatly improving fatigue resistance under alternating thermal loads
Precision thread rolling/turning, thread tolerance strictly controlled, uniform stress distribution to prevent thread cracking
Fine polishing & deburring on all surfaces; optional surface strengthening treatments: nitriding, black oxide, zinc plating, passivation
Slotted lock nuts with evenly distributed milling slots for reliable anti-loosening locking with lock tabs
Performance Under Extreme Conditions
High temperature resistance: No permanent creep deformation under long-term high-temperature operation
