How to use
Select the known material family and processing condition to see its general magnetic response.
Example calculation
Annealed 304/316 usually has no significant attraction; ferritic 430 is attracted.
Calculation method
Results use the stated subset of the sources below. Numerical conversions and limits are explicit.
Calculation limits
A magnet cannot establish exact grade or corrosion resistance. Cold work and welding change the response. This tool cannot certify an unknown part as 304 or 316.
