Stainless Steel 416 Stainless Steel Supplier Stainless Shapes is a proud 416 Stainless Steel supplier. 416 Stainless has a machinability of 85%, meaning it is the most workable stainless on the market. This machinability means that we provide it in multiple forms, such as tempered, hardened, or unhardened. You can even increase that machinability more with the inclusion of manganese sulphide and other chemical additives. This is martensitic steel, meaning it can be tested non-destructively and has high hardness. Despite these two bonuses, they have lower corrosion resistance than austenitic steels. In conclusion, they have low ductility at sub-zero temperatures and higher strengths with over-tampering. 416 Stainless Steel Characteristics Corrosion Resistance – These have high resistance to acids. However, they have less corrosion than austenitic grades, 430 Ferritic, non-free-machining steels, and any steel with +17% chromium. They are created with smooth surfaces and high corrosion resistance in mind. Regardless, these should stay away from chlorides and marine environments. Heat Resistance – They will be able to withstand temperature differences of 1160-1400 Fahrenheit, depending on the continuous conditions. As a result, 416 should NOT be employed at temperatures higher than normal tempering conditions. Treatment and Welding – 416 offers poor weldability, but can be carried by preheating to 400-572 and stress relieved to 1200. Full Annealing – Annealed to a temperature of 1500-1650 for half an hour and followed with air-cooling after setting it at 85 degrees. Sub-Critical – 1200-1400 and air-cooled. Hardening – Scorch it up to 1700-1850, quench with oil and temper, this will improve the mechanical properties of the steel. Tempering should not be carried out at temperatures ranging from 750 to 1075 due to low ductility. Not Sure What You’re Looking For? Contact us today at Stainless Shapes.

Call - 800-748-9811 Frequently Asked Questions What is the difference between 416 and 316 steel? + Grade 416 is a martensitic free-machining stainless -- magnetic, hardenable, and excellent for machining but with lower corrosion resistance. Grade 316 is austenitic -- non-magnetic, non-hardenable, and with far superior corrosion resistance due to its molybdenum content. They serve completely different applications. Will 416 stainless steel rust? + Grade 416 can corrode if exposed to humid, saline, or chemically aggressive environments. Its corrosion resistance is lower than 304 or 316. In dry indoor conditions, it performs adequately, but for marine or chemical exposure, it is not the right specification. What is the strongest grade of stainless steel? + Among standard grades, precipitation-hardening alloys like 17-4 PH in the H900 condition achieve the highest tensile strength (200+ ksi). For maximum hardness, 440C reaches 58-60 HRC. Grade 416 is hardenable but does not reach these premium levels. Is 416 stainless good for knives? + Grade 416 can produce serviceable knife blades, but it is not the preferred choice for quality cutlery. Its corrosion resistance is limited and after hardening it is brittle compared to 440C. 416R (the rifle barrel grade) is optimized for precision machining rather than knife-making. Will a magnet stick to 416 stainless steel? + Yes, a magnet will stick to 416 stainless steel. It is a martensitic grade -- inherently magnetic -- unlike austenitic grades (304, 316) which are generally non-magnetic. What is 416 steel used for? + Grade 416 is used for high-volume machined parts including nuts, bolts, screws, studs, gears, valve components, and pump shafts where machinability is the primary requirement and moderate corrosion resistance is acceptable. Its sulfur addition makes it the most machinable of all standard stainless grades. What are the three grades of stainless steel? + The three most commonly referenced stainless families are austenitic (304, 316), ferritic (430, 409), and martensitic (410, 416, 440C). Stainless Shapes stocks all three families across multiple grades and product forms. Is 416 stainless expensive? + Grade 416 is comparably priced to 410 and somewhat less expensive than 304 in bar form due to its lower nickel content. It is among the more economical stainless bar grades. Contact Stainless Shapes for current pricing on specific sizes. What is the best grade of stainless steel? + The best grade depends entirely on the application. For corrosion resistance, 316 or duplex 2205. For high strength, 17-4 PH H900. For maximum hardness, 440C. For best machinability at low cost, 416. Stainless Shapes can advise on grade selection. Is 416 stainless hard to machine? + No -- Grade 416 machines very easily. It has the highest machinability rating of all standard stainless steels (approximately 85-90% of 1212 free-machining carbon steel). The sulfur addition breaks chips cleanly and extends tool life significantly compared to 304 or 316.
