EN 1.4303, ASTM TYPE 305 / UNS S30500 Stainless Steel

General Characteristics

305/4303 is a high-nickel alternative to 304/4301 with reduced strain hardening and excellent cold forming properties. Ideal for parts that require high deformation degrees.


305/4303 is an austenitic stainless steel that belongs to the standard CrNi stainless steel family. It has 12.5 wt.-% nickel for improved formability.


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. 305/4303 is available in many product forms and dimensions. It can be supplied with a wide range of functional and aesthetic surface finishes.

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.
