314 Stainless Steel (1.4841)

314 stainless steel is a high-temperature alloy known for excellent oxidation resistance, strength at elevated temperatures, and durability in demanding industrial environments.

314 Stainless Steel

314 stainless steel (1.4841) is an austenitic, heat-resistant stainless steel designed for exceptional performance in high-temperature applications. With a chemical composition rich in nickel (25–27%) and chromium (19–22%), it delivers outstanding resistance to oxidation and carburisation, making it ideal for furnace parts and thermal processing equipment.

The addition of silicon (around 1.5%) enhances its ability to withstand carburising atmospheres, while molybdenum (2–3%) improves resistance to pitting and crevice corrosion. This combination of alloying elements makes 1.4841 stainless steel a reliable material for use in aggressive, high-heat environments across sectors such as petrochemical, chemical processing, and power generation.

Thanks to its good mechanical properties, 314 offers high tensile and yield strength along with reliable creep resistance. It is a trusted choice for components that face sustained exposure to elevated temperatures, often being used alongside or in place of 310S (1.4845) stainless steel.

FAQs: 314 Stainless Steel

What are the Mechanical Properties of 314 Stainless Steel?

The mechanical strength of 314 stainless steel contributes to its suitability for high-stress, high-temperature environments. Typical values include:

Yield Strength: 205–310 MPa (30–45 ksi)

Tensile Strength: 515–655 MPa (75–95 ksi)

Elongation at Break: 40%

Hardness (Brinell): 217 HB

These mechanical characteristics help ensure that the material retains its form and functionality under intense thermal and mechanical stress.

Where is 314 Stainless Steel Used?

314 stainless steel is engineered for high-temperature service, and is widely used in industries that require reliable performance under extreme conditions. Common applications include:

Furnace components

Heat exchangers

Heat treatment equipment

Petrochemical and chemical plant infrastructure

Power generation components

Its strong resistance to scaling and carburisation makes it ideal for thermal environments where lesser alloys would degrade.

Are There Variants of 314 Stainless Steel?

While 314 stainless steel typically refers to a single high-temperature alloy, it is known by several international designations depending on regional standards or manufacturers:

AISI 314
UNS S31400
W.Nr. 1.4841
EN X15CrNiSi25-20
JIS SUS314

These identifiers all refer to the same alloy grade, although minor variations may exist in composition or performance specifications. Always consult manufacturer datasheets for precise tolerances.

What is the Chemical Composition of 1.4841 Stainless Steel?

The typical composition of 314 stainless steel includes:

Nickel (Ni): 25–27%

Chromium (Cr): 19–22%

Silicon (Si): ~1.5%

Molybdenum (Mo): 2–3%

Iron (Fe): Balance

This precise alloy blend allows for enhanced resistance to scaling, carburisation, and corrosion, particularly in high-heat and aggressive chemical environments. The high nickel and chromium content also contributes to thermal stability and a long service life.
