EN 1.4305, ASTM TYPE 303 Stainless Steel

General Characteristics

It gives you faster machining, longer tool life, better tolerances, superior machined surface quality, and reduced scrap losses compared to conventionally produced 303/1.4305. 


It is an austenitic stainless steel that belongs to the standard CrNi stainless steel family. It is a sulfur-alloyed variant with improved machinability. Due to its high sulfur content, the corrosion resistance of 303/1.4305 can be slightly lower than the corrosion resistance of grade 1.4301.


The austenitic CrNi standard grades are the most widely used group of stainless steels. Their well-balanced material properties make them suitable for the fabrication of many products.


Typical Applications

  • Nuts, bolts, and screws

  • Gears

  • Shafts

  • Bearings

  • Machined parts for process equipment

Mechanical Properties

The mechanical properties of the available products in soft annealed condition at room temperature are given in the table below. Moderate strengths can be reached at elevated temperatures (~550 °C/1022 °F). Temperatures for excessive scaling are close to 850 °C/1562 °F. 


This grade, along with other austenitic corrosion-resistant steels, exhibits very high ductility and high elongation to fracture. It is not susceptible to brittle fracture in the solution annealed condition.
