Abstract

The invention discloses a Ca and Ru-containing lead alloy for a lead bath for austenitic heat treatment and processing process thereof. The Ca and Ru-containing lead alloy is prepared from the components in percentage by weight of 1.5-2.4 wt% of Ca, 0.2-0.8 wt% of Ru, 0.5-1.0 wt% of In, 3.0-5.0 wt% of Cu, 1.0-2.0 wt% of Sr, 0.4-0.8 wt% of Hf and the rest of Pb. The development of the lead alloy for austenitic heat treatment can promote China to develop new high-quality materials independently and occupy the international market of new high-quality materials.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a lead alloy. Background technique [0002] my country's steel production and structural varieties are increasing year by year. Steel production enterprises have also been committed to the optimization of production processes. Through equipment improvement and process adjustment, the broken wire rate of each production process is continuously reduced, and production efficiency and comprehensive yield are improved. Heat treatment refers to a metal thermal processing process in which the chemical composition and structure of the surface or interior of the material are changed by means of heating, heat preservation and cooling in the solid state to obtain the required properties. Heat treatment is one of the important processes in the manufacturing process of mechanical parts and tools and molds. [0003] Heating is one of the important processes of heat treatment. The heating mean...
