1.2842 Tool Steel

1.2842 TOOL STEEL

APPLICATION

1.2842 tool steel is suitable for manufacturing all kinds of precision measuring tools and templates. It is also used for stamping dies, cold pressing dies, engraving dies, blanking dies, etc. with relatively small size. It can also be used as structural parts such as screw rods of machine tools. It is used to manufacture all kinds of cold punching dies and tools with large section, complex shape and heavy working conditions, such as punching die, trimming die, edging die, deep drawing die of steel plate, circular saw, standard tools and gauges, thread rolling die, etc.

1.2842 STEEL CHARACTERISTICS

1.2842 steel is a high-quality non deformable cold working tool steel, supplied with a hardness of 220-230HBW and a requirement of 63HRC. This steel is easy to forge, with good hardening dimensional stability and good machinability. Compared with carbon tool steel, 1.2842 steel has higher hardness and wear resistance, smaller deformation during quenching, and good punching ability.

The chemical composition of 1.2842 steel mainly includes elements such as carbon, silicon, manganese, phosphorus, and sulfur. Among them, the higher carbon content is beneficial for improving the hardness and wear resistance of the steel. Elements such as silicon and manganese can increase the strength and toughness of steel, while impurities such as phosphorus and sulfur have a lower content, which is beneficial for improving the quality and performance of steel.

The hardness of 1.2842 steel is relatively high, usually between HRC60-64. This makes it have good wear resistance during the cutting process and can withstand large cutting forces. Meanwhile, the higher hardness also makes the tool less prone to deformation and damage during use. Although 1.2842 steel has high hardness, its toughness is not high. Steel is prone to fracture when subjected to impact or significant pressure. Therefore, when using 1.2842 steel to manufacture cutting tools, attention should be paid to avoiding excessive impact and overload. 1.2842 steel has good thermal stability and can maintain its hardness and wear resistance at high temperatures. This makes it suitable for high-speed cutting and continuous cutting, capable of withstanding large amounts of heat. 1.2842 steel has certain grindability, and its hardness and wear resistance can be improved through heat treatment and grinding. By appropriate heat treatment, the hardness and toughness of steel can be improved; By grinding, the friction coefficient between the tool and the workpiece can be reduced, improving cutting efficiency. 1.2842 steel has high cutting performance and can maintain good cutting effects during the cutting process. Due to its high hardness and wear resistance, the cutting tool is not easily worn during the cutting process, thus ensuring cutting quality.

The production process of 1.2842 steel mainly includes processes such as smelting, forging, and heat treatment. During the smelting process, it is necessary to strictly control the ratio of various elements to ensure the performance and quality of the steel. During the forging process, it is necessary to perform multiple processes such as upsetting, elongation, and rolling on the steel to eliminate internal stress and improve its microstructure. The heat treatment process mainly adjusts the hardness and toughness of steel through quenching and tempering to meet the requirements of different working conditions.
