Stainless steel 1.4305
AISI: 303 / DIN: X8CrNiS18-9 / PN: 1.4305
It is an austenitic stainless steel grade. Due to the sulfur content, it is the best among austenitic stainless steel grades in terms of workability. The corrosion resistance of this material is lower than that of 1.4301 steel grade. The main areas of application are machinery, automotive industry, electronic equipment and turned parts for the food industry.
Steel type 1.4305 exhibits specific physical properties that contribute to its overall performance. With a density of 8.03 Kg/m³, it possesses a moderate weight while maintaining structural integrity. The high melting point of 1455 °C enables its application in high-temperature environments. Additionally, its thermal expansion coefficient of 17.2 x 10^-6 /K ensures minimal dimensional changes under varying temperatures. With a modulus of elasticity of 193 GPa, it demonstrates excellent stiffness and resistance to deformation. The material's thermal conductivity of 16.3 W/m.K facilitates efficient heat transfer, while its electrical resistivity of 0.072 x 10^-6 Ω.m highlights its electrical conductivity characteristics. These physical properties make steel type 1.4305 a suitable choice for a wide range of industrial applications.
To create 1.4305 stainless steel, a specific chemical composition is required, which consists of various elements. The composition includes approximately 69% iron (Fe), 17-19% chromium (Cr), 8-10% nickel (Ni), 2.0% manganese (Mn), 1.0% silicon (Si), 0.20% phosphorus (P), and a maximum of 0.15% carbon (C). Additionally, the composition specifies a minimum of 0.15% sulfur (S). These carefully balanced elements contribute to the unique properties and characteristics of Type 303 stainless steel.
