en 1.4301 yield strength

What is the grade 1.4301 equivalent to?
Material 1.4301 (X5CrNi18-10) is the European standard for the widely used AISI 304 stainless steel, also known as 18/8 stainless steel, representing its common 18% Chromium/8% Nickel composition, with equivalents like UNS S30400 and BS 304S31. It's a versatile austenitic steel prized for corrosion resistance, good formability, and weldability, used in kitchenware, architecture, and food processing.

What is the maximum yield strength of 1.4301 stainless steel?
The tensile strength of 1.4301 stainless steel is at a minimum of 515 MPa and can typical reach 625 MPa as a maximum. The yield strength of 304 stainless steel is at 205 MPa. When the steel is placed under stress at 205 MPa or higher it will become permanently deformed.

Corrosion Resistance

304 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 chloride-containing environments. Stress corrosion cracking may occur above 60°C.

 

Heat Resistance
304 stainless steel has good oxidation resistance under intermittent use, up to 870°C; it also has good oxidation resistance under continuous use, up to 925°C. However, continuous use at temperatures between 425-860°C is not recommended.

 

Heat Treatment
304 stainless steel cannot be hardened by heat treatment. Solution treatment or annealing can be achieved by heating to 1010-1120°C followed by rapid cooling.

 

What are the differences between 1.4301 and AISI 304?
Sulfur content: The sulfur content of 1.4301 (≤ 0.015%) is lower than that of SS 304 (≤ 0.03%), which may have a slight impact on machinability. The mechanical properties of SS 304 and 1.4301 are very similar, with only minor differences due to standard testing methods and regional variations.

 

What is the difference between 1.4301 and 1.4307 stainless steel?
The main difference is that 1.4307 (304L) is a low-carbon version of 1.4301 (304), which makes it better for welding applications because it has improved resistance to intergranular corrosion in the heat-affected zone. While 1.4301 has slightly higher mechanical strength, 1.4307 offers superior weldability and long-term corrosion resistance after welding.
