SUS440C Stainless Steel Bar

SUS440C stainless steel bars are mainly used for manufacturing bearing parts that work in corrosive environments and strong oxidizing atmospheres without lubrication. 440C has good high-temperature dimensional stability, so it can also be used as a 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. However, 440C has a relatively low ability to withstand dynamic loads.

Characteristics of SUS440C Stainless Steel Bar:

Due to its high chromium content and the effect of alloying elements, SUS440C stainless steel bars have good corrosion resistance in common environments such as the atmosphere and water.

It also has a certain degree of resistance to some weak acidic and weak alkaline media. However, in strongly corrosive media, its corrosion resistance may be limited.

In the annealed state, SUS440C stainless steel bars have good workability and can be processed and formed through conventional processing methods such as forging, rolling, and cutting.

Since SUS440C stainless steel bars have relatively high hardness, appropriate cutting tools and processing techniques need to be used during the processing to reduce tool wear and processing difficulty. For example, when performing cutting processing, cemented carbide cutting tools are usually required, and appropriate cutting parameters should be selected.
