tool steel (low alloyed)

Do you need spring steel but the needed dimensions are beyond the manufacturing dimensions?
 
In this case 75Cr1 might be a possible alternative. Its chemical analysis is comparable to C75S – the most popular spring steel quality.
 
With 75Cr1 you have got the advantage of expanded widths and thicknesses.
 
75Cr1 is available in hardening grades: annealed, 42-44 HRC and 48-50 HRC.
