Traditionally, segments for hot rolling were made from low-alloy cast steel products of Cr-Mo or Mn-Cr systems, or high-temperature and high-pressure cast steel products of the Cr-Mo system. However, these materials were discarded due to friction, deformation, and surface heat cracks, with heat cracks generated by heating and cooling being a major cause of reduced lifespan. Therefore, materials with excellent heat crack resistance were required. By increasing the carbon content in steel, hardenability can be improved, and wear resistance and deformation resistance can be addressed through tempering adjustments. However, increasing the carbon content also decreases heat crack resistance and impact values, so materials with higher carbon content do not yield good results under the harsh operating conditions of segments. Our developed YST-5 minimizes the carbon content necessary to improve heat crack resistance, adding special elements to a composition of 1.3% Cr and 1.0% Mo, and applying special heat treatment. As a result, it maintains the mechanical properties required for segments, exhibits excellent heat crack resistance, has no temper brittleness, and retains temper resistance, making it the optimal material for the harsh operating conditions of segments.

Miyako Steel primarily produces cast steel products. As steelmaking technology involving refining is gradually being lost, our steelmaking technology has been passed down and evolved since our founding in 1904. Furthermore, in addition to this technology, we have installed a ladle refining furnace (LF furnace). This document explains our steelmaking technology using an electric arc furnace plus LF furnace, as well as the features and advantages of the N process, which is an inorganic self-hardening mold.

The "LDX210C" is an eco stainless steel casting that has twice the strength compared to austenitic stainless steel, excellent toughness, and comparable corrosion resistance. Basically, it is a duplex stainless steel material, which means it has excellent weldability and does not require considerations for post-heat treatment, making it ideal for structural welding. Additionally, as a cost-effective low-Ni duplex stainless steel casting, it is effective for applications that aim to reduce costs by replacing austenitic stainless steel and to lessen environmental impact by replacing SC series castings. 【Features】 ■ Twice the strength compared to austenitic stainless steel ■ Excellent toughness ■ Excellent corrosion resistance ■ Applicable for reducing environmental impact *For more details, please download the PDF or feel free to contact us.
