Abstract

The article examines the optimization of heat treatment for producing thin-walled pipes via cold rolling from high-strength corrosion-resistant steel 15Kh15N4AGM-Sh. The high strength of this steel after quenching (σв > 1700 MPa) makes deformation difficult. It was established that annealing the steel leads to significant embrittlement. Tempering at 600–700 °C forms a highly tempered martensite structure, reducing strength (σ0,2 ≈ 990 MPa at 600 °C) while maintaining ductility (δ5 ≈ 19 %). Based on the research results, it was determined that the best reduction in strength characteristics without a significant decrease in ductility occurs in temperature range 630–660 °С.
