Abstract
A high heat resistant steel with low nickel has high tensile strength and high heat resistance at a high temperature, wherein a value of X/Y is 0.44 to 0.47, and wherein the X is a value calculated by Equation 1, [Equation 1 is X=wt % of Cr+wt % of 1.5×Si+wt % of 0.5×Nb], and the Y is a value calculated by Equation 2 [Equation 2 is Y=wt % of Ni+wt % of 0.5×Mn+wt % of 30×C+wt % of 30×N].
