WEAR-RESISTANT PLATES OF STEEL acc. to VN 414320 (ABRAZIT)
14320 steel grade is fine-grain steel used for rolling of plates for production of steel parts exposed to extreme abrasion and mechanical wear.
Our abrasion resistant steel plates are delivered as rolled (without heat treatment –steel grade 14320.0) or as soft annealed (
steel grade 14320.3). Machining in the condition without heat treatment is difficult; in the soft annealed it‘s good.
Cold forming is not possible,
hot forming at temperature of 850–1,150 °C is good.
Joints between parts are usually made as bolted joints; or in the form of fixing welds, using preheating up to 200 °C at minimum (thickness up to 10 mm without preheating); however the welded joint does not reach the strength of the parent base. Cutting plates by means of flame cutting, or flame cutting shaped plates is also performed with preheating up to 200 °C at minimum. Shearing is not recommended for plate cutting.
Tensile strength (Rm) in the condition without heat treatment (grade 14320.0) is approx. 930 to 1,370 MPa, the lowest yield strength (ReH) is approx. 75 % of the tensile strength, the lowest elongation (A5) is 8 % and Brinell hardness is approx. 270 to 400 HB. Tensile strength can be improved to approx. 1,400 MPa by quenching. Tensile strength, yield strength, and elongation are not subject to testing and acceptance inspections because test samples are difficult to be made.
