Stainless Steel 440C
Stainless Steel 440C is categorized as high-carbon martensitic stainless steel because of its:
✅ Exceptional toughness
✅ Increased resistance to abrasion
✅ Average protection against corrosion
Since it can be magnetized and hardened through heat treatment, it can be used for the following:
🔧 Gage blocks
🍴 Cutlery
⚙️ Ball bearings and races
🛠️ Molds and dies
