常见问题 (FAQ)
What is the difference between SS400 and S45C steel?
SS400 is general structural steel (tensile ≥400 MPa); S45C is medium-carbon machinery steel (0.45% C). S45C has superior strength, hardness, and machinability but costs more.
What is the difference between SUS304 and SUS430 stainless steel?
SUS304 is austenitic (non-magnetic, excellent corrosion resistance, weldable); SUS430 is ferritic (slightly magnetic, cheaper, harder to weld).
