Ni Hard 4 Nickel Sand Casting High Chromium Hard Cast Iron Liner For Industrial Use AS2027 Wear Liner ASTM A532

Ni-Hard 4 sand cast liners combine an abrasion-resistant alloy white iron with a component shape defined for industrial equipment. The liner acts as a replaceable wear element, allowing the contacting surface to be specified separately from the machine structure it protects. This listing focuses on material definition, casting geometry and the inspection details needed for an industrial liner order.

Ni-Hard 4 material characteristics

Ni-Hard 4 is a nickel-chromium white iron with a carbide-containing structure. Its wear behaviour depends on both the hard constituents and the surrounding matrix. Heat treatment and section size are therefore relevant to the delivered casting, not merely additional words in the product description.

The material is considered for abrasive service, with the actual operating duty determining suitability. A liner handling sliding particles and one exposed to repeated concentrated impact may need different design decisions. The quotation should connect the grade to the intended duty and the finished component.

Sand casting and liner geometry

Sand moulding establishes the main outline, thickness and cast features of the liner. The drawing then identifies the fixing details, seating faces and any surfaces that need additional finishing. A clear distinction between the cast outline and the critical installation features helps define what the customer receives.

For curved or shaped liners, include the profile reference and how neighbouring pieces meet. Hole locations should be related to the mounting surface, not just measured from an edge that may not locate the liner in the equipment. These details are important for replacement compatibility.

Standards and acceptance requirements

AS2027 NiCr4-600 is the material designation used for this product. Where an order references ASTM A532, identify the required class, type and delivery condition in the purchase specification. A general standard number is not a substitute for the actual grade and acceptance criteria.

Agree the hardness test method, measurement location and sampling requirements with the specified material condition. Dimensional inspection addresses the mounting and profile requirements. Chemistry records or additional examinations can be included in the order when required for the project.

Selecting a liner for the operating duty

Industrial enquiries may include grinding and material-handling equipment, with the specific liner location identified on the drawing. Useful operating information includes the handled material, feed size, impact conditions and previous wear pattern. This information supports selection without assigning one calendar lifetime to every installation.
