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
