Welding Stainless Steel
Martensitic Stainless Steels (12-16%Cr)
- Used for cutlery and sharp tools
- These form martensite when welded
Preheat to 200-300oC and post heat to about 700oC and slow cool to remove brittleness
Filler rods of similar composition are available but do not give good results - use an austentic stainless rod
