Nickel Alloy Steel Hot Rolled Bar

Hot rolled bars are economical bars processed through hot rolling technology, featuring high production efficiency, significant cost advantages, and wide specification range. They are widely used in general machinery manufacturing, structural component processing, fastener production, and other fields. The nickel alloy hot rolled bars supplied by Hefei Tailan Metal Co., Ltd. are manufactured from high-quality nickel-based alloy continuous casting billets or rolled billets through multiple processes including heating, multi-pass hot rolling, online controlled cooling, straightening, and saw cutting. Featuring uniform structure, stable mechanical properties, good surface quality, and large-scale supply capability, they are specifically designed for industrial applications with requirements for cost and delivery time, while maintaining certain material performance standards.

Hot Rolling Process Characteristics:

1. Hot Rolling: Rolling above recrystallization temperature, high production efficiency, low cost
2. TMCP (Thermo-Mechanical Control Process) : Controlled rolling and cooling processes, optimizing structure and properties
3. Online Straightening: Ensuring bar straightness
4. Saw Cutting to Length: Supplied in standard lengths or cut to customer requirements

Supply Range

Diameter (d): 10mm – 300mm (3/8 inch – 12 inches); Larger sizes negotiable

Length (L): Random length: 3-9 meters; Fixed length: Precision cut as per customer requirements

Shape: Round, Square, Flat, Hexagon

Diameter Tolerance: Ordinary Tolerance: ±0.5mm – ±1.5mm; Higher Tolerance: ±0.3mm – ±1.0mm

Straightness ≤3mm/m (Hot Rolled); ≤1.5mm/m (after straightening)

Multiple Delivery Conditions Available

Various delivery conditions available according to subsequent processing requirements:

1. Hot Rolled: Most economical, suitable for rough machining or forging blanks
2. Pickled: Scale removed, easy for surface inspection and subsequent processing
3. Turned: Surface defects removed, higher dimensional accuracy
4. Annealed: Reduced hardness, improved machine-ability

Dimensional Inspection

1. Diameter: Online or offline inspection using calipers, laser diameter gauges
2. Ovality: Measuring maximum and minimum diameters, calculating ovality
3. Length: Measuring using tape measures

Surface Quality Inspection

1. Visual Inspection: Inspecting surface for cracks, folds, scars, scratches, and other defects
2. Pickling Inspection: Pickling when necessary to expose surface defects
