416 Stainless Steel Round Bar Supplier
Circle H Steel provides quality, long-length 416 stainless steel round bar for industrial applications.
Grade 416 is the free-machining version of the basic martensitic stainless steel, Grade 410. It achieves the highest machinability of any stainless steel, at approximately 85% of that of free-machining carbon steel. As a result, corrosion resistance, weldability, and formability are lower than those of its non-free-machining equivalent, Grade 410.
Grade 416 is a cost-effective grade often supplied in the unhardened, or hardened and highly tempered condition, valued for its low cost and ready machinability. As with other martensitic stainless steels, it is optimised for high hardness.

416 Stainless Steel Properties
- Chemistry: 12.0-14.0% Chromium, 0.15% max Carbon, 0.15% min Sulphur, martensitic free-machining stainless steel. Sulphur is added to improve machinability, forming manganese sulphide inclusions. As a martensitic grade, 416 is magnetic in all conditions.
- Corrosion Resistance: Useful resistance to dry atmospheres, fresh water, and mild alkalies and acids. Less corrosion resistant than equivalent non-free-machining grades, and less than austenitic grades and 17% chromium ferritic alloys such as Grade 430. 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 up to 760°C in intermittent service and up to 675°C in continuous service. Not recommended for use above the relevant tempering temperature, where maintenance of mechanical properties is important.
- Machining: 416 stainless steel offers the highest machinability of any commonly available stainless steel. Best machinability is achieved in the sub-critical annealed condition, where it can be turned, threaded, drilled, or formed at speeds approaching those of free-machining carbon steel.
- Welding: Grade 416 has poor weldability due to its sulphur content. If welding is necessary, use Grade 410 low-hydrogen electrodes with a pre-heat of 200-300°C. Follow immediately with annealing, re-hardening, or a stress relief at 650-675°C. Where the weld is not required to be hard, Grade 309 austenitic stainless steel filler rod is a better option.
- Heat Treatment: Full annealing is performed by heating to 815-900°C for half an hour per 25mm of thickness, cooling at a maximum rate of 30°C per hour to 600°C, then air cooling. Sub-critical annealing is done by heating to 650-760°C and air cooling. Hardening is achieved by heating to 925-1010°C and quenching in oil, then tempering to suit mechanical requirements. Note: the tempering range of 400-580°C should be avoided due to poor ductility.
