Stainless Steel for Nuclear Power Systems

Supplying material options aligned with strict quality control, traceability, and long-term operational requirements.

Nuclear Power Plant Featured Image
  • Excellent radiation resistance

    Effectively resist the effects of nuclear radiation, maintain stable material structure and performance.

  • Strong corrosion resistance

    Withstand high temperature, high pressure and highly corrosive media in nuclear power plants.

  • Stable and fast supply

    10,000 tons of standing inventory, 2-week regular production cycle.

Where These Grades Are Used in Nuclear Facilities

Heat Exchanger Piping

  • Grade & form: 800H seamless pipe (OD 50–150 mm, WT 3–8 mm)
  • Why for manufacturers: 800H is commonly specified for elevated-temperature service where oxidation resistance and high-temperature strength are required. We can support order-defined inspection scope and documentation to match project requirements.

Ventilation System Piping

  • Grade & form: 446 welded pipe (OD 100–300 mm, WT 2–6 mm)
  • Why for manufacturers: 446 is often selected where oxidation resistance and high-temperature corrosion performance matter for ducting and ventilation-related piping. Inventory support helps respond to construction and maintenance needs tied to outage schedules.

Electrical Equipment Housings

  • Grade & form: 321H plate (2–5 mm)
  • Why for manufacturers: 321H (Ti-stabilized) is widely used where resistance to intergranular corrosion is needed after welding and thermal exposure, making it suitable for fabricated housings. Plates can be supplied with cutting and bending coordination based on your fabrication workflow.

Focusing on providing high-quality stainless steel plates, tubes, coils, and rods, we have supplied high-quality raw materials to nuclear power plants around the world since 2015 to ensure the reliable operation of nuclear power facilities.

Built Around Outage Schedules and Verification Workflows

Support for Outage-Window Procurement

Nuclear projects often purchase around planned outages. We help align batching, item grouping, and shipping readiness so materials arrive in time for shutdown maintenance windows.

Documentation Chain That Stays Consistent

Traceability, inspection records, and document packaging can be prepared in a consistent format to support project review and downstream acceptance routines.

Repeatability for Replacement and Retrofit Parts

For long-life facilities, replacement parts must match installed systems. We support repeat-order consistency by locking key requirements (grade/form/dimensions/notes) for future reorders.

Clear Change Control for Critical Requirements

If substitutions or adjustments are needed, we help communicate changes early and clearly to reduce approval delays and on-site rework.
