416 Stainless Steel Flat Bar

The 416 Stainless Steel Flat Bar is renowned as the ultimate choice for machinability in stainless steels, thanks to its unique sulfur content. This martensitic stainless steel flat bar features a specific chemical composition:

• Iron (Fe) base
• Carbon: <0.15%
• Chromium: 12.0-14.0%
• Manganese: <1.25%
• Silicon: <1.0%
• Phosphorus: <0.06%
• Sulfur: >0.15%

Applications and Characteristics of 416 Stainless Steel Flat Bar

The 416 Stainless Steel Flat Bar offers distinct advantages and limitations:

Key Features:

• Superior machinability
• Heat treatment capability
• Moderate corrosion resistance
• Cost-effective material choice
• High strength in tempered state

Common Applications:

• Precision fasteners (bolts and nuts)
• High-speed machined components
• Gear manufacturing
• Valve parts
• Pump shafts
• Motor shafts
• Washing machine components

Important Considerations:

• Limited weldability (410 grade recommended for welding)
• Suitable for dry atmospheres
• Resistant to fresh water
• Moderate resistance to mild acids/alkalies
• Not recommended for marine environments
• Unsuitable for chloride exposure

The stainless steel flat bar in grade 416 is particularly valued in applications requiring extensive machining operations while maintaining moderate corrosion resistance. Its excellent machinability makes it a cost-effective choice for high-volume production of precision components.
