One bar of hot rolled 440C Stainless Steel measuring 4 x 38 x 915 mm. Actual thickness as hot rolled is 4.5 mm+.
440C stainless steel is a classic, well-balanced, high-quality cutlery stainless steel. It is the standard against which other stainless steel is compared, and its formula is the basis from which many newer stainless steels have been developed.
440C should not be confused with lower carbon stainless steels 440A and 440B, which have lesser edge holding.
