WebThe cracks can be wide and open and possibly narrow. Solidification cracking occurs in compositions having a wide freezing temperature range. For steels, solidification cracks occur due to the presence of high carbon content and impurity elements like sulfur and phosphorus.During solidification, these elements segregate such that intergranular liquid … Web13 de abr. de 2003 · Short answer: repass the welds. If you rerun the weld it can drive out the pores and increase the weld penetration as well as improve the weld appearance. In EB welding it is called a cosmetic pass but it is a really useful means of cleaning up a weld. Topic Welding Industry / Technical Discussions / welding carburized, high carbon steel.

WebHigh carbon steel is also used for the ring gear of a powertrain. However, since these two base materials contain high carbon content, the weldability is not very good because both of these materials have high equivalent carbon content (CE). The CE can be calculated by the following equation: CE = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15 Web18 de fev. de 2024 · Both GB/T9943-2008 for High-Speed Tool Steel and GB/T1299-2014 for Tool Steel have specific regulations regarding the porosity of steel, ...
