Leading Manufacturer, Supplier & Retailer of Stainless Steel 440 and Stainless Steel Sheets and Plates.
Applications:
Heat Treatment:
Welding:-If welding is necessary pre-heat at 250°C and follow welding with a full anneal. Grade 420 filler will give a high hardness weld (although not as high as the 440C), but 309 or 310 will produce soft welds with higher ductility.

Alternative Grades
| Grade | Why it might 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 |
