What are the characteristics and parameters of 440C stainless steel ball?
440C stainless steel ball has high hardness in all stainless steel and heat resistant steel. For nozzles and bearings. 440F: it is a steel grade that improves the easy cutting performance of 440C steel. For automatic lathes. Martensite stainless steel has the same hardening characteristics as ordinary alloy steel, so a wide range of different mechanical properties can be obtained by selecting brands and heat treatment conditions.
440C stainless steel carbon content C-1. % Of this kind of steel has good rust resistance and is commonly used stainless steel for import and production of knives. Its chromium content is as high as 16- 18%, also one of the stainless steel used for cutting tools, is very popular. If heat treatment is carried out as stainless bearing steel, it is generally recommended to carry out cryogenic treatment before tempering operation. Such cryogenic treatment improves the hardness of steel, increases wear resistance and dimensional stability. Therefore, the cryogenic treatment of 440C is also often used for tool heat treatment. The annealing temperature of 440 stainless steel ball is very low. When heat treatment is carried out as a tool and bearing, the recommended hardness is HRC57- 59. If cryogenic treatment is carried out, the hardness can reach hrc60.
440 stainless steel ball stainless steel is a high carbon and high chromium Markov stainless steel. The carbon content is 1. 0%, chromium content 17%. Scope of Application: it is mainly used to manufacture bearing parts working in corrosive environment and non-lubricating strong oxidation atmosphere. 440 stainless steel ball has good high temperature dimensional stability, so it can also be used as corrosion-resistant high temperature bearing steel. In addition, it can also be used to manufacture high-quality cutting tools, such as medical scalpels, scissors, nozzles, bearings, etc. The 440 stainless steel ball has a low capacity to withstand dynamic loads.
SUS440 stainless steel ball this steel is Markov stainless steel with higher carbon content than 3cr13 steel, so its strength and hardness are higher than 3cr13 steel. Other properties are similar to 3cr13 steel. However, the weldability is poor and is usually not used as welding material. Used to manufacture surgical medical tools. SUS440 stainless steel ball stainless steel imported from Japan is used to manufacture bearing parts that work in corrosive environment and without lubrication and oxygenation. The steel also has good high-temperature dimensional stability, and can be used to manufacture corrosion-resistant high-temperature bearings and tools with temperatures not exceeding 250 ℃. Hardness: annealing, ≤269hb; Quenching and tempering, ≥55hrc. Heat treatment specification: 1)Annealing, 800 ~ Slow cooling at 900 ° C; 2)Quenching, 1000 ~ 1050 ° C oil cooling; 3)Tempering, 200 ~ Air cooling at 300 ° C.
