314 / 1.4841

314 stainless steel is a high-temperature alloy with excellent resistance to oxidation and carburization, suitable for furnace parts and heat treatment equipment.

314 stainless steel, also known as 1.4841, is a high-temperature alloy that is characterized by its excellent resistance to oxidation and carburization. It is a heat-resistant steel grade that is often used in furnace parts and heat treatment equipment. The steel is known for its good mechanical properties, high temperature strength, and good creep resistance.

The chemical composition of 314 stainless steel includes nickel (25-27%), chromium (19-22%), silicon (1.5%), and molybdenum (2-3%). The high nickel content gives the steel good corrosion resistance, while the chromium provides good oxidation resistance at high temperatures. The molybdenum improves the steel's resistance to pitting and crevice corrosion, while the silicon improves its resistance to carburization.

314 stainless steel has a melting point of 1454-1510 °C (2650-2750 °F) and a density of 8.0 g/cm3. It has a high yield strength of 205-310 MPa (30-45 ksi) and a high tensile strength of 515-655 MPa (75-95 ksi). Its elongation at break is 40%, and its hardness (Brinell) is 217 HB.

The steel is suitable for use in furnace parts, heat exchangers, heat treatment equipment, and other high-temperature applications. Some of the common industries that use 314 stainless steel include petrochemical, chemical, and power generation. It is also used in the production of furnace parts, heat exchangers, and other high-temperature equipment.

In summary, 314 stainless steel (1.4841) is a high-temperature alloy with excellent resistance to oxidation and carburization, suitable for furnace parts and is often paired or inter-changed with 310s / 1.4845

Chemical Composition of 314 / 1.4841

The chemical composition of 1.4841 (314) stainless steel typically includes:

  • Chromium (Cr): 19-22%

  • Nickel (Ni): 25-27%

  • Silicon (Si): 1.5%

  • Molybdenum (Mo): 2-3%

  • Iron (Fe): Balance

Please note that these values are typical and may vary depending on the specific grade and manufacturer of the stainless steel. As always, it's recommended to check the specification from the manufacturer or supplier.

The high chromium content provides good oxidation resistance at high temperatures, while the nickel content gives the steel good corrosion resistance. The molybdenum improves the steel's resistance to pitting and crevice corrosion, while the silicon improves its resistance to carburization. The high nickel and chrome content also gives the steel a good thermal stability.

The physical properties of 1.4841 (314) stainless steel include:

  • Density: 8.0 g/cm3

  • Melting Point: 1454-1510 °C (2650-2750 °F)
