Description

нию со скоростью 2-10 град/мин, сварке , окон ательной закалке на воздухе от 1100°С, травлению и холодной прокатке. При смотке полосы в рулон и холодной прокатке образование трещин не происходило , качество ленты соответствовало предъ вл емым требовани м по механическим свойствам.with a speed of 2-10 degrees / min, welding, final hardening in air from 1100 ° С, etching and cold rolling. During the coiling of the strip into a roll and cold rolling, no cracking occurred, the quality of the tape met the requirements for mechanical properties.

Применение предлагаемого способа позволит получать ленту из сварной гор чекатаной полосы дисперсионно-твердеющей стали мартенситного класса, имеющих высокую скорость упрочнени  при коротких выдержках.The application of the proposed method will make it possible to obtain a tape from a welded hot rolled strip of dispersion-hardening steel of martensitic class, having a high hardening rate at short exposures.
