Free cross-section and hot-pressed steel materials compatible with processing-less design that reduces machining and welding processes.
Hot-pressed steel materials
For designers who face material loss from machining and the labor involved in distortion correction after welding. This is a shape steel material that allows for consideration of a process transition to machining-free manufacturing through integral forming with a free cross-section.
Hot-pressed shape steel is a type of shaped steel that is formed by extruding round billets heated to approximately 1200°C through a die designed for the specified cross-sectional shape. It is suitable for designers looking for "processing-free" materials that reduce the amount of cutting waste from machined materials and minimize the labor involved in heat distortion and distortion correction caused by assembly welding. 【Recommended for the following issues】 - Excessive cutting waste makes materials feel wasted - Labor-intensive distortion correction after welding - Increased number of parts leads to longer assembly processes

basic information
<Reasons for Selection> - Complex cross-sections formed in one piece according to the die - Elimination of cutting, welding, and distortion correction processes - Compatible with materials from ordinary steel to stainless steel At Kumagai Special Steel, we accommodate cross-sectional shapes that fit within a diameter of φ215mm, supporting ordinary steel, carbon steel, high-tensile steel, and stainless steel. We can consult on post-processing of components utilizing hot-pressed shapes, including drilling, surface machining, bending, and welding fabrication, and we also support delivery in the state of parts. We will consider whether it can be replaced with machined materials or welded structures based on the drawings. For detailed manufacturing methods and examples of shapes, please download our catalog or contact us.

※We will manufacture custom shapes to order. It takes more than six months from consultation to production and delivery. Please first consult with our company, Kumagai Special Steel, about your desired shape.
Applications/Examples of results
It can be utilized in the design of components such as mechanical parts and building materials, where the same cross-sectional shape continues along the length. For processes that involve cutting complex cross-sections from thick plates or round bars, which are perceived to generate a lot of chips and take a long time, switching to hot-pressed steel with a cross-section close to the final shape can help reduce cutting processes and material waste. In frame materials and structural components that are welded together from multiple steel materials, re-evaluating to a seamless integral cross-section makes it easier to omit welding work and the post-welding distortion correction process. It also accommodates complex cross-sections that are difficult to achieve with standard steel shapes, as well as components that combine design and structure. This approach is suitable not only for new designs but also for considering VA/VE of existing parts, model changes, and transitioning manufacturing methods for machined or welded assembly products. The material, cross-sectional shape, and necessary additional processing are confirmed through CAD drawings and documents to assess the feasibility of hot-pressing.
