What is 1.4303 stainless steel?
1.4303 stainless steel is a high-nickel austenitic stainless steel (also known as AISI 305 or X4CrNi18-12) that exhibits excellent deep drawing and cold forming properties due to its stable austenitic structure and low work hardening rate. Therefore, it is ideally suited for the manufacture of complex shapes in the automotive, construction, and mechanical engineering industries, and also possesses good corrosion resistance and non-magnetic properties.
What is the equivalent of 1.4303 stainless steel?
The equivalent of EN 1.4303 stainless steel is primarily AISI 305 in the USA, also known as X4CrNi18-12 in European (EN) chemical notation and SUS305J1 in Japan (JIS), offering excellent cold formability due to its high nickel content for increased corrosion resistance.

AISI 305 / 1.4303 stianless steel Corrosion resistance
Stainless steel AISI 305 (1.4303 / X4CrNi18-12) has good corrosion resistance (PREN value 18.0 to 20.7) in natural environmental media without chlorine and salt content (e.g. water and steam). This stainless steel is also resistant to weak acids at low temperatures. The material is not resistant to salt and seawater and should not be used in heavily chlorinated media such as swimming pools
What is the hardness of 1.4303 stainless steel?
The hardness of 1.4303 (AISI 305) stainless steel varies by condition, but typically falls around ≤ 215 HB (Brinell) or 190-270 HB for general ranges, with specific values like ~240 HB (Vickers) or ~96 Rockwell B for annealed states, showing its characteristic low work-hardening for excellent formability.
Is 1.4303 stainless steel magnetic?
No, 1.4303 (also known as AISI 305) stainless steel is inherently non-magnetic, as it's an austenitic steel with high nickel content, designed for excellent deep drawability and corrosion resistance, remaining non-magnetic even after cold working, unlike some other stainless steels that can become magnetic when formed.
What are the differences between 1.4303 and 1.4301 stainless steel?
1.4303 (AISI 305) differs from 1.4301 (AISI 304) primarily in its higher Nickel (Ni) content, leading to better resistance to certain corrosion types, reduced work hardening (easier deep drawing/forming), and a more stable austenitic structure, while 1.4301 offers slightly higher general strength but work hardens more easily, making 1.4303 ideal for deep-drawn parts and 1.4301 for general, robust applications.
