Rostfreier Stahl 304 in der CNC-Bearbeitung
Edelstahl 304 ist ein in der CNC-Bearbeitung häufig verwendetes Material. Er ist bekannt für seine Korrosionsbeständigkeit und seine mechanischen Eigenschaften.
Choosing sharp carbide tools for milling and incorporating cobalt-based or carbide end mills is important when working with this stainless steel grade. Lower cutting speeds and moderate feed rates help prevent overheating and tool wear. Coolants and lubricants aid in dissipating heat and improving tool life. Employing climb milling, proper workpiece securing, and effective chip control contribute to a smooth machining process. Post-machining, consider annealing for applications where work-hardening may occur. Attention to tolerances and surface finish is also important, and regular tool wear monitoring ensures continued quality and efficiency.
The chemical composition of Type 304 stainless steel, as per ASTM A276/A276M standard, is specified by certain percentage values. The composition includes a maximum of 0.08% carbon (C), 1.00% silicon (Si), 2.00% manganese (Mn), 0.045% phosphorus (P), and 0.030% sulfur (S). It also contains 18.0-20.0% chromium (Cr) and 8.0-11.0% nickel (Ni). This composition defines the material properties and characteristics of Type 304 stainless steel. It finds wide applications in both household and industrial settings. It is commonly used in food handling and processing equipment, machinery parts, screws, utensils, and exhaust manifolds. It is also used for exterior accents like water and fire features in architectural projects.

Grundkenntnisse of Stainless Steel 304
What is Stainless Steel 304?
Stainless steel 304 is a widely used type of stainless steel with a composition that includes 18-20% chromium and 8-10.5% nickel. As an austenitic stainless steel, it lacks magnetic properties and exhibits lower electrical and thermal conductivity than carbon steel.
Known for its high corrosion resistance, it is easily molded into various shapes. Developed by W. H. Hatfield in 1924 and initially marketed as "Staybrite 18/8," this steel is part of SAE International's steel grades. It goes by various names and designations, such as 4301-304-00-I, X5CrNi18-9, UNS S30400, A2 stainless steel, 18/8, 18/10 stainless steel, SUS304, 1.4301, 06Cr19Ni10, and ISC S30408, depending on international standards and specifications.
