SUS 416 Metal Rod UNS S41600 Free Cutting Steel Stainless Steel Round Bar OD 50MM
Alloy 416 is a martensitic, free-machining, chromium steel alloy that is generally considered to be the first free-machining stainless steel. It has the highest machinability of any stainless steel at about 85% of that of a free-machining carbon steel. Martensitic stainless steels were designed to be hardenable by heat treatment and also corrosion resistant. Although Alloy 416 and other martensitic stainless steels are not as resistant as austenitic or ferritic stainless, it still demonstrates good corrosion and oxidation resistance plus high strength in the hardened and tempered condition. Alloy 416HT is easily machined, is always magnetic, and has low frictional properties that reduce galling and seizing.
Specifications: UNS S41600
APPLICATIONS:
Alloy 416 is generally used for parts that are extensively machined and require the corrosion resistance of a 13% chromium stainless steel. Applications that generally use Alloy 416 include:
- Electrical motors
- Nuts and bolts
- Pumps
- Valves
- Automatic screw machine parts
- Washing machine components
- Studs
- Gears
STANDARDS:
- ASTM/ASME: UNS S41600
- EURONORM: FeMi35Cr20Cu4Mo2
- DIN: 2.4660
CORROSION RESISTANCE:
- Demonstrates corrosion resistance to natural food acids, waste products, basic and neutral salts, natural waters, and most atmospheric conditions
- Less resistant that the austenitic grades of stainless steel and also the 17% chromium ferritic alloys
- High sulfur, free-machining grades like Alloy 416 are unsuitable for marine or other chloride exposure
- Maximum corrosion resistance is achieved in the hardened condition, with a smooth surface finish
HEAT RESISTANCE
- Fair resistance to scaling in intermittent service up to 1400oF (760oC) and up to 1247oF (675oC) in continuous service
- Not recommended for use in temperatures above the relevant tempering temperature if maintenance of mechanical properties is important
PROCESSING
WELDING CHARACTERISTICS
- Poor weldability
- If welding is necessary use Alloy 410 low hydrogen electrodes
- Pre-heat to 392 to 572°F (200-300°C)
- Follow immediately with annealing or re-hardening, or a stress relief at 1202 to 1247°F (650 to 675°C)
MACHINABILITY
- Has outstanding machinability
- Best machinability is in the sub-critical annealed condition
