Manufacturing Process
Our Cold Drawn 304 Stainless Steel Square Bar is produced through strict quality control:
Each 304 Stainless Steel Square Bar undergoes chemical composition analysis, mechanical testing, dimensional inspection, and surface quality checks before shipment.
1. What is ASTM A276 304 Stainless Steel Square Bar?
ASTM A276 304 Stainless Steel Square Bar is a solid square stainless steel bar manufactured in accordance with ASTM A276. It offers excellent corrosion resistance, good weldability, and outstanding mechanical properties for industrial applications.
2. What is the difference between hot rolled and cold drawn 304 stainless steel square bar?
Cold Drawn 304 Stainless Steel Square Bar provides tighter dimensional tolerances, a smoother surface finish, and improved mechanical properties, making it ideal for precision machining. Hot Rolled 304 Stainless Steel Square Bar is more economical and typically used for structural or general engineering applications.
3. Do you provide custom sizes?
Yes. We supply custom dimensions, cut-to-length services, precision machining, and various surface finishes according to customer requirements.
4. What certifications do you provide?
We can provide EN 10204 3.1 Mill Test Certificate (MTC), chemical composition reports, mechanical property reports, and other inspection documents upon request.
5. What is the standard length of 304 Stainless Steel Square Bar?
Common lengths are 3 meters, 4 meters, and 6 meters. Custom lengths are available based on your project requirements.
