Product Description
S40C 1040 C40/1.0511 Medium Carbon QT Steel
1: C40 Steel Introduction
C40 steel plate is one mainly of high carbon steel, DIN 17200 C40 steel plate is meduim Carbon Steels are similar to low carbon steel except that the carbon ranges from 0.30 to 0.60% and the manganese from 0.50 to 1.65%. Increasing the carbon content is approximately 0.5% with an accompanying increase in manganese allows medium carbon steels to be used in the quenched & tempered conditions. This steels are of particular importance because of unique combination of strength& toughness after heat treat treatment.
