ABSTRACT
Cold drawn products are widely used in the construction industry. Drawn products are obtained by a drawing process in which the most important tool is the drawing tool. Drawn products include wire, bar and pipe. The material used in this study was a drawing die mesh made of sintered carbide, grade H10S. The abrasive wear analysis of prepared samples was carried out using the ball on disc method with a ZrO2 ceramic ball. Hardness measurements were carried out using the Vickers method in accordance with the PN-EN 23878:1996 standard. The resistance to brittle fracture was determined based on the length of the measurement of cracks formed at the corners of the impression.
