INTRODUCTION
Often referred to as “razor-blade steel” due to its frequent use in the manufacture of razors and cutlery, grade 440 stainless steel provides high strength and moderate corrosion resistance. Extremely versatile, it’s used in a wide range of industries to create specialized, small-scale products and is available in various types: 440A, 440B, 440C, and 440F.
COMMON APPLICATIONS
Besides being used for cutlery and razorblades, 440 stainless steel is also used for small applications such as dental and surgical instruments. Its high heat and corrosion resistance make it ideal for engine parts like rolling bearings and valve seats, and with superior hardness and abrasion resistance, it’s particularly well suited to manufacturing precision pivot pins and rollers.

Through the use of heat treating and quenching, grade 440 stainless steel can be both annealed and hardened. In its annealed form, this material exhibits good machinability, but its high carbon content — and, therefore, its high hardness — can make it difficult to work with. Because its high sulfur content makes it easily machinable, type 440F is ideal for applications requiring extensive machining.
Basic Properties of 440 Stainless Steel
Comparing Types of 440 Stainless Steel
POSSIBLE ALTERNATIVE GRADES TO 440C
| Grade | Reason it may be chosen instead of 440C |
| 440A/B | Slightly softer and more corrosion resistant grade needed |
| 440F | High machinability required, with same hardness and hardenability as 440C |
| 420 | Lower strength and hardness needed than any of the 440 grades |
| 416 | Higher machinability required, and the much lower hardness and strength is still adequate |
