Conclusions
- 1.
Two-layer steel 30+Kh12 can be hot worked at 1050–1170°. Plastic deformation is even, which makes it possible to avoid stresses in the boundary between the two layers.
- 2.
At heating rates of 20–80 deg/sec there is a narrow temperature range that, after cooling with water to 200–250°, produces a wear resistant structure of metastable austenite in the cladding layer of steel Kh12.
