Model: D32-1200*S1-120
The hot rolled seamless steel pipe replaces the semi-circle plate. The pipe is rolled under a relatively low temperature with a larger deformation during intermediate rolling, so that the austenite grain is finer. The quenching and tempering allows the high toughness and performance stability of the products.
