Quenched & Tempered Steel Plate
Atlas Specialty Metals stocks and distributes quenched and tempered plate, a steel that is stronger and harder than ordinary carbon steel. The product is used for the manufacture and repair of machinery and structures where greater abrasion resistance or higher yield strength are required. Atlas commonly stocks the Bisalloy brand range of quenched and tempered plate that is readily available in a multitude of grades and thicknesses. Bisalloy is a quality Australian-made steel free of mill scale and imperfections, offering characteristics of good workability and weldability.
Bisplate 80
High strength, low alloy structural steel with controlled carbon equivalent for optimum weldability. This plate can be successfully welded to itself and a range of other steels, provided low hydrogen consumables are used and attention is paid to preheat, interpass temperature, heat input and the degree of joint restraint.
Stress relieving can be achieved at 540ΊC-570ΊC. Heating above this temperature should be avoided to minimise adverse effects on mechanical properties. This plate can be successfully cold formed, provided allowances are made for the increased strength of the steel.
Applications. Utilising the high strength properties of Bisplate 80 allows reduction in section thickness, without loss of structural integrity.
Common applications:
| Transport equipment | Lifting equipment |
| Mining equipment | Induced draft fans |
| High-rise buildings | Bridges |
| Excavator and loader buckets | Storage tanks |
Bisplate 360
High hardness, abrasion-resistant steel with a controlled carbon equivalent for optimum weldability. With attention to heat input, preheat and consumable selection, Bisplate 360 can be readily welded to itself and other steels, using conventional processes.
This plate can be successfully cold formed, provided allowances are made for the high strength of the steel. Adequate allowance must be made for increased springback relative to mild steel.
Heating above 400ΊC should be avoided, otherwise the mechanical properties may be affected.
Atlas Specalty Metals stocks and distributes quenched and tempered plate, a steel that is stronger and harder than ordinary carbon steel. The product is used for the manufacture and repair of machinery and structures where greater abrasion resistance or higher yield strength are required.
Atlas commonly stocks the Bisalloy brand range of quenched and tempered plate that is readily available in a multitude of grades and thicknesses. Bisalloy is a quality Australian-made steel free of mill scale and imperfections, offering characteristics of good workability and weldability.
Applications. Through the plates hardness and good mechanical properties this grade is the most popular wear plate in Australia. It has been extensively used in the following areas:
| Wear liners | Deflector plates |
| Chutes | Earthmoving buckets |
| Storage bins/hoppers | Longwall pan lines |
| Cyclones | Gear wheels |
Bisplate 500
Medium carbon, high hardness and abrasion-resistant steel. With attention to heat input, preheat and consumable selection, Bisplate 500 can successfully be welded to itself and a range of other steels. The high hardness causes difficult cold forming, requiring higher bending and cold forming forces along with greater allowances for springback.
Applications. The hardest steel produced by Bisalloy and offers exceptional long life in sliding abrasion applications such as:
| Dump truck wear liners | Cutting edges |
| Chutes | Earthmoving buckets |
| Wear liners | Ground-engaging tools |
