303 vs 304 Stainless Steel

Posted by Umang


It is next to impossible to identify the difference between 303 and 304 as they have similar properties and characteristics. These stainless steel grades have various features and properties, and the quality is enriched with high weldability and robustness. Stainless steel 303 and 304 grades have different chemical compositions, one of the main differences between these two grades.


Since the grade 303 material includes a high amount of sulfur which makes it a perfect grade for machining. Similarly, 304 has less sulfur content which makes it an ideal application for commercial and industrial usage. Grade 303 and 304 are used in concrete machinery. The application of the grade depends upon the heat tolerating capacity of the grade.

Stainless Steel Grades


Key properties:
Grade 303 and 304 stainless steel have similar properties and characteristics. Both the grades have excellent workability and high heat-bearing capacity despite being the most extraordinary grade in the industry. Stainless steel 304 has high tensile and yield strength. The minimum tensile strength of grade 304 is 515mpa, whereas the minimum yield strength is 720 mpa. The grade also has high welding and pitting capacity, which makes it an ideal application for industrial and commercial usage.
