what is material 1.4301 stainless steel?
1.4301 is a versatile austenitic stainless steel, known as "classic V2A," highly valued for its excellent corrosion resistance, good formability (deep drawing), and weldability. Its 18/8 chromium-nickel composition allows for the formation of a self-healing protective oxide layer, making it widely used in applications such as kitchenware, architectural decoration, and food processing equipment.
What material is 1.4301 equivalent to stainless steel?
Material 1.4301 is the European standard (EN) designation for the widely used AISI 304 stainless steel, also known as X5CrNi18-10. It is an austenitic stainless steel containing 18% chromium and 8% nickel, and is the most common type of stainless steel, sometimes referred to as "18/8". It is equivalent to UNS S30400, JIS SUS 304, and BS 304S31.
Is EN 1.4301 the Same as AISI 304 Stainless Steel?
Yes, EN 1.4301 and AISI 304 stainless steel are essentially the same; they simply use different naming standards but refer to the same widely used austenitic stainless steel grade. Due to its 18% chromium and 8% nickel content, it is commonly known as "18/8 stainless steel." There are slight differences in their chemical composition, for example, 1.4301 has a slightly lower sulfur content.

Application areas of 1.4301 Stainless Steel
The wide application of 1.4301 stainless steel includes:
Kitchen equipment: such as sinks, workbenches, and kitchen utensils.
Architectural decoration: used for handrails, exterior wall decoration, and building structures.
Chemical equipment: used to manufacture reactors, storage tanks, and piping systems.
Medical equipment: used for surgical instruments, implants, and other medical devices.
1.4301 Corrosion Resistance
1.4301 stainless steel exhibits excellent corrosion resistance in a variety of environments and when in contact with different corrosive media. Pitting and crevice corrosion may occur in environments containing chlorides. Stress corrosion cracking may occur at temperatures above 60°C.
1.4301 Heat Resistance
1.4301 stainless steel can withstand oxidation up to 870°C under intermittent use conditions; and up to 925°C under continuous use conditions. However, continuous use in the temperature range of 425-860°C is not recommended. In this case, 1.4307 stainless steel is recommended.
1.4301 Stainless Steel Heat Treatment
304 stainless steel cannot be hardened by heat treatment. Solution treatment or annealing can be performed by heating at a temperature of 1010-1120°C followed by rapid cooling.
Differences between 1.4301 and 1.4305 stainless steel:
Both 1.4301 (AISI 304) and 1.4305 (AISI 303) are austenitic stainless steels with similar compositions, but 1.4305 has added sulfur to improve its machinability, making it easier to cut and shape than 1.4301. However, this addition slightly reduces the corrosion resistance of 1.4305, especially in highly corrosive environments.
Differences between 1.4301 and 1.4306 stainless steel:
The main difference between 1.4301 (AISI 304) and 1.4306 (AISI 304L) is the carbon content. 1.4306 has a lower carbon content than 1.4301 (less than 0.03%), which improves its resistance to intergranular corrosion, especially in welded structures exposed to high temperatures. 1.4306 also has better weldability and is less prone to sensitization, making it ideal for applications requiring welding.
Differences between 1.4301 and 1.4404 stainless steel:
The main difference between 1.4301 (AISI 304) and 1.4404 (AISI 316L) lies in the alloying elements. 1.4404 contains molybdenum (2-3%), which significantly enhances its resistance to pitting and crevice corrosion, especially in chloride-rich environments such as seawater or acidic conditions.
