Title:
High chromium heat resisting steel
Document Type and Number:
Japanese Patent JP6144417
Kind Code:
B2
Abstract:
The present invention provides a high-chromium heat-resistant steel. The steel contains in mass %, C: 0.08% to 0.13%; Si: 0.15% to 0.45%; Mn: 0.1% to 1.0%; Ni: 0.01% to 0.5%; Cr: 10.0% to 11.5%; Mo: 0.3% to 0.6%; V: 0.10% to 0.25%; Nb: 0.01% to 0.06%; N: 0.015% to 0.07%; B: ≤0.005%, and Al: ≤0.04%. The balance consists of Fe and inevitable impurity elements. The steel shows a martensitic microstructure.
