Frequently Asked Questions
Which is stronger, 304 or 6061?
304 has a tensile strength of 585 MPa while 6061 reaches 2.9E+2 MPa, making 304 the stronger alloy in ultimate tensile terms. For yield strength, 304 is rated at 235 MPa versus 2.2E+2 MPa for 6061.
Does 304 or 6061 have better corrosion resistance?
304 offers better corrosion resistance. 304 rates 7/10 and 6061 rates 6/10 on the corrosion resistance scale.
Is 304 or 6061 easier to weld?
Weldability data is not available for both alloys. In terms of machinability, 304 scores 4/10 and 6061 scores 8/10. 6061 is easier to machine overall.
Which is more cost-effective, 304 or 6061?
6061 is generally more cost-effective. 304 has a cost rating of 6/10 and 6061 has 7/10 (higher means more affordable). Note that 304 (Stainless Steel) and 6061 (Aluminum) have different base metals, so raw material costs and availability may vary significantly by region.
Can I use 304 instead of 6061 for structural applications?
304 provides 585 MPa tensile strength versus 2.9E+2 MPa for 6061, so it meets or exceeds the structural strength requirement. Always validate substitution against your specific design codes and operating conditions.
