1.4125 round steel
1.4125 Round steel is a martensian-type stainless steel. Carbon content 1.0%, chromium content 16-18%. Strong rust resistance, is high quality stainless steel.
Scope of application: Mainly used for manufacturing bearing parts in corrosive environment and strong oxidation atmosphere without lubrication. 440C has good dimensional stability at high temperature, 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 and so on. The ability of 1.4125 round steel to bear dynamic load is low.

1.4125 Application scope of round steel
Mainly used for manufacturing bearing parts in corrosive environment and strong oxidation atmosphere without lubrication. 440C has good dimensional stability at high temperature, 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 and so on. 1.4125 round steel F: It is a kind of steel that can improve the easy cutting performance of 440C steel. It is used for automatic lathes and ordinary alloy steel, which has the same characteristics of hardening through quenching. Therefore, a wide range of different mechanical properties can be obtained by selecting the brand and heat treatment conditions. The ability of 1.4125 round steel to bear dynamic load is low. [1]
Delivery status
1.4125 round steel is generally delivered in heat treatment condition, and the type of heat treatment is indicated in the contract; If not indicated, the goods shall be delivered in non-heat treatment condition
The special editor reports
1.4125 Round steel: high strength cutting tool steel, slightly higher carbon content, after proper heat treatment can obtain high yield strength, hardness can reach 58HRC, belongs to the hardest stainless steel. The most common example is the "razor blade". There are three common models: 440A, 440B, 440C, and 440F (easy to work).
