The microstructure of 15CrMo steel in the normal supply state is ferrite plus pearlite, and the long-term operation of 15CrMo steel in the range of 500 -550 will produce pearlite spheroidization, redistribution of alloying elements between solid solution and carbide and change of carbide phase structure, and the thermal strength and mechanical properties of 15CrMo steel gradually decrease with the increase of the degree of pearlite spheroidization and the dilution degree of solid solution alloying elements, so that the material gradually deteriorates or even fails.
Today, the local market is weak and stable. Specific to today's market performance, the main local brand Shente ** continued to hold steady in early trading, except for the shortage of individual brands and the increase **, 15crmog alloy steel pipe market dealers mostly maintained on Friday**. In terms of merchant feedback, the market transaction continued to be weak on the weekend, and the downstream procurement was more wait-and-see, and in terms of the morning transaction, there were few inquiries, and the market did not have the usual lively atmosphere on Monday, so some merchants began to loosen to facilitate the transaction. In addition, according to the feedback of downstream users, some specifications of market resources are in short supply, but this week, merchants have successively replenished the warehouse, and the shortage of resources may be improved. At present, the wait-and-see atmosphere of procurement is strong, the transaction of merchants is sluggish, and the weather conditions are not very good this week, and the mentality of merchants is weak. There has been no significant change in market transactions, and some merchants are still shipping upside down, and merchants are feeling a little pressure. Towards the end of the month, merchants continued to reduce the cash flow of inventory return, and it is expected to continue to adjust weakly. Although the steel electronic disk is in the first trend, but the willingness of merchants in the local market is not strong, but due to the weakening of downstream procurement enthusiasm, the market wait-and-see mentality has increased, once the steel continues to be in the first situation in recent days, the market will undoubtedly follow, the market mentality is not optimistic. Steel mills: Shagang announced today that the order volume in June was 85% off. It can be seen that in the process of continuous production, the signs of production reduction and maintenance of steel mills are not obvious, and merchants are still facing the risk of high inventory in the later stage.
