Product Performance
- Pure and Stable Material: The hot rolling process ensures dense structure without internal defects. Each bar comes with a label and material certificate, with uniform composition and strong traceability.
- High Process Adaptability: Black skin round bars are suitable for deep processing such as forging, heat treatment and rough turning. The oxide scale can be removed in subsequent processing, with high blank utilization rate.
- Excellent Corrosion Resistance: 316L material has strong pitting and intergranular corrosion resistance, suitable for equipment manufacturing in harsh environments such as chemical and marine industries.
- Stable Mechanical Properties: After normalizing treatment, the grains are uniform and mechanical properties are stable, suitable for structural parts under heavy loads.
Product Applications
- Heavy Machinery Manufacturing: Large forgings, pressure vessel blanks, gear shafts, crankshafts, heavy drive shafts.
- Chemical Equipment: Reactor shafts, mixing shafts, valve bodies, high-pressure pipe fittings.
- Marine Engineering: Platform components, marine machinery accessories, corrosion-resistant equipment blanks.
- Mold Manufacturing: Large mold blanks, forging mold raw materials, mechanical sliders.
Features & Highlights
- Strong Traceability: Each bar is labeled with furnace number, material and specifications, with full quality traceability.
- Wide Specification Coverage: Complete large-diameter specifications, up to 300mm, meeting heavy blank requirements.
- High Blank Utilization Rate: Hot rolled round bars can be directly used as rough machining blanks, reducing pre-preparation costs.
