AISI 1038/1040 steel plate/sheet

AISI 1038/1040 steel plate/sheet is one mainly of high carbon steel, SAE J 403-AISI 1038/1040 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. The equivalent steel grades of AISI 1038/1040 are DIN 40, UNI C40, NF 1C40 and BS 080M40.
