Stainless Steel 410 / 430 / 409 Slatting Coils is non- hardenable by thermal treatment, but may be cold worked to high tensile strengths. Stainless Steel 410 Perforated Coils is resistant to a wide variety of mild to moderately corrosive environments. 410 Stainless Steel Sheets has corrosion resistance approaching that of SS 301 and has been successfully substituted for SS 304 in many mild environments and in many applications. 410 Stainless Steel Plates is essentially nonmagnetic in the annealed condition and becomes magnetic when cold worked. The annealing temperature for 410 Stainless Steel Coils is between the ranges of 1850 Degree F - 2000 Degree F. Meanwhile, rapid cooling of SS 410 Sheets through the carbide precipitation range (1500 Degree F - 800 Degree F) is necessary to keep the carbides in solution and prevent sensitization. SS 410 Plates is not hardenable by thermal treatment and is only hardenable by cold working. SS 410 Coils can be welded by all conventional methods applied to 18 percent chromium, 8 percent nickel steels.
