Cold and hotworking properties of 1Cr1Mo0.25V0.45Ti0.60Nb0.07Cb 0.03N Steel
1Cr1Mo0.25V0.45Ti0.60Nb0.07Cb 0.03N steel is a newly developed high chromium vanadium molybdenum steel. Due to its high chrome and high vanadium contents, it has strong wear resistance and excellent hardenability. It is widely used in industries such as shipbuilding, petrochemical, and construction machinery. In order to ensure its application performance, the cold and hot working properties of this steel must be studied.
Because of its high chromium and molybdenum content, 1Cr1Mo0.25V0.45Ti0.60Nb0.07Cb 0.03N steel needs to be hardened and tempered after hot rolling to make it work harden. The hot rolling process usually contains multi-passes, and the amount of reduction should not exceed 60%. A continuous casting process would also be suitable for the hot rolling of 1Cr1Mo0.25V0.45Ti0.60Nb0.07Cb 0.03N steel. The reduction rate should still be kept at less than 60% to ensure the best working performance of the steel.
The hot die forging process of 1Cr1mo0.25V0.45Ti0.60Nb0.07Cb 0.03N steel is complex and requires professional machining skills. The steel should be preheated to 850 to 900℃ and then kept at a certain temperature during the forging process to ensure optimal working performance.
The cold working process of 1Cr1Mo0.25V0.45Ti0.60Nb0.07Cb 0.03N steel is very similar to that of ordinary steels, but due to the differences in the mechanical properties of the steel, the machining parameters should be chosen cautiously. The choice of tools is also important. To ensure low risk, hard and wear resistant tools should be used for the cold working of 1Cr1Mo0.25V0.45Ti0.60Nb0.07Cb 0.03N steel. For further assurance, the tools should be regularly maintained and sharpened.
The welding of 1Cr1Mo0.25V0.45Ti0.60Nb0.07Cb 0.03N steel is relatively simple and can be done using ordinary methods such as fusion welding and submerged arc welding. In addition, to ensure reliability in the welding process, preheating and post-weld heat treatment should be conducted. A preheating temperature of 500-600℃ is recommended for the preheating process, and a tempering temperature of 450-520℃ should be adopted for the post-weld heat treatment.
To sum up, 1Cr1Mo0.25V0.45Ti0.60Nb0.07Cb 0.03N steel has good cold and hot working properties, which makes it suitable for many applications. However, in order to optimize its performance and reduce the risk of failure, appropriate tools, preheating and post-weld heat treatments should be chosen for its cold and hot-working processes. Consequently, the reliability and longevity of 1Cr1Mo0.25V0.45Ti0.60Nb0.07Cb 0.03N steel can be maintained.
