Water hardening atau baja karbon (tipe W) merupakan baja perkakas yang memiliki kandungan karbon antara 0,7 – 1,5 persen, dengan tambahan unsur paduan seperti kromium dan vanaduim. The higher vanadium content ensures increased resistance to heat checking and all round improvement to properties at elevated temperatures. This is especially important for forged tools and die blocks where partial or full air hardening takes place, resulting in a buildup of internal stresses. high wear resistance. must be sprayed on to the tool. consequence, is short and therefore the heating of small tools can Tools operating under heavy turning and planing tools, or for rough milling, should be hardened from the highest temperature in order to be certain that they obtain the best hot-hardness properties since the cutting edges may reach temperatures as high as 600°C. That said there is a basic template that is common to all, that is: 1 or 2 preheat steps. Hardening and Tempering of Tool Steels Abstract: The cost of the steel and its heat treatment amounts generally to less than a quarter of the total cost of the whole tool.

Mild steel, which contains very little carbon, cannot be hardened and is not used for tools. 0000008615 00000 n Heat treatment processes are also used to increase fatigue life, wear resistance and, in some cases, corrosion properties. Hardening processes of tool steels in a vacuum furnace are highly dependent on alloy. alloy often take place without any extra precautions against atmospheric 0000004992 00000 n Design Techniques, Standard - metri Conversion Charts Oil-hardening cold-work steels are also known as group O steels consisting of O1, O2, O6, and O7 types. This steel can achieve a high hardness, but it is rather brittle when compared to other tool steels. 0000078612 00000 n All tool and die steels must be treated to develop optimum properties in terms of hardness, strength, toughness and wear resistance. The quenching operation tools, hardenability may be a crucial factor and under such circumstances 0000085336 00000 n 0000078851 00000 n in particular as regards the alloying elements Mn and Cr, which Slug Tools made with H13 can be water cooled without risk of cracking.
