8. Material character:
1)Type 440C is a martansitic stainless steel with high carbon and high chromium content.
2)It has the highest hardeness of any stainless steel for heat resistance,but it is less resistant to dynamic loading.
                                                                                            

9. Application:
1)Highest resistance can be achieved through hardening and polishing, and the properties of 440C steel make it ideal for knife blades and cutting instruments like surgical blades. 
2)This grade, once hardened, hold a sharp edge and resists corrosion, and can be polished to a near mirror finish.
3) Its toughness and ability to resist wear makes 440C stainless steel a good choice for tools like chisels and ball bearings.
