Overwhelming cost-effectiveness! Reducing costs of stainless and high-alloy materials! By joining expensive high-alloy steel with carbon steel and chrome-moly steel, we achieve cost reduction and functionality.
Are you still using solid stainless steel or high alloy materials? How about switching to clad steel plates? Our staff will provide full support even for customers using clad steel plates for the first time! ~Our clad steel plates have excellent workability! We have extensive experience in accommodating a wide variety of combinations!~ 【Main Features】 - Clad steel plates are composite steel plates that bond expensive alloys to carbon steel/low alloy steel. - They possess various features not found in single steel plates and are functional materials with excellent cost-effectiveness. - They are used in a wide range of fields, primarily in oil and gas, as well as in marine development, power, environment, infrastructure, chemicals, and food sectors. - Cost reduction in materials, ensuring corrosion resistance and strength.
Clad steel plates made of stainless steel and high alloy steel achieve both heat resistance and corrosion resistance.
The base material for rolled clad steel plates is not only carbon steel. Our company is also capable of producing clad steel plates with special combinations such as stainless steel + high alloy. For example, there are combinations like SUS304 + NCF625 and SUS310S + NW2201, which involve stainless steel and nickel-based alloys. Clad steel plates with such combinations are often used in equipment that requires both heat resistance and corrosion resistance, such as kilns for powder sintering and dryers for drying. **Advantages of Clad Steel Plates with Stainless Steel + High Alloy Steel** - **Economy**: By reducing the amount of relatively expensive high alloy steel and using stainless steel as the base material, we can lower material costs compared to steel plates made solely of high alloy steel. - **Improved Steel Plate Strength**: If there are concerns about the strength of high alloy steel, using materials like stainless steel for the base can enhance material strength. - **Wide Width Capability**: It can be difficult to obtain wide steel plates made solely of high alloy steel. In our case, we can produce wide steel plates due to the rolling process, with our product widths generally accommodating up to 3.5 meters. Using wide steel plates can reduce the number of weld seams in equipment.

This is a SUS steel build H-beam that has undergone sandblasting. The customer consulted us about whether we could blur the noticeable scratches that occurred during manufacturing with blasting.
◎ Build H Steel (BH English: build H) If you need a cross-section that is not available in standard H steel, we create Build H by welding. The welding can be corner welds or complete penetration welds with K-shaped grooves, depending on the structural design. Welding distortion is corrected by air cooling or water cooling after heating. Stainless steel is often used in its raw form without painting, so we sometimes receive inquiries like this. The product this time had relatively noticeable machining marks, but we were able to hide the overall scratches by taking the time to sandblast it. Blurring the scratches takes time, but it can lead to uneven application, so we repeatedly check to ensure that the aesthetics do not worsen. Since the delivery time was the shortest possible, we shipped the next day after arrival. Harada Iron Works Hiroshima Official Link

Not just rubber. Considering the longevity of crushing blades that wear out from contact with tire cords.
In the tire shredding process, not only the rubber but also the internal tire cords (reinforcing wires) are processed. Due to repeated friction and impact on the blade edges, ordinary steel can wear down, leading to challenges in blade replacement and repair. In such a wear environment, we propose Nippon Steel's wear-resistant steel plate "ABREX." Not only the blades but also the liners of the shooters and conveyors face wear issues. It is possible to utilize the wear-resistant steel plate ABREX for these as well. ABREX is a wear-resistant steel plate that combines excellent wear resistance and workability. By using it in areas with severe wear, such as shredding blades and shredder blades, an extension of component life and a reduction in replacement frequency can be expected. At Kumagai Special Steel, we will confirm the drawings and usage conditions and provide support from the selection of steel type and plate thickness to cutting, drilling, machining, and welding.
Extend the lifespan of the bottom and side plates, which wear out due to the input and transportation of scrap and earth, by using wear-resistant steel plates.
The beds of dump trucks and scrap collection vehicles that transport soil and other materials are subjected to impacts during the loading of soil and metal scraps, as well as abrasion of the bottom and side plates every time they are loaded and unloaded. As wear progresses, repairs or replacements become necessary, which can also affect the vehicle's operation. Therefore, we propose the use of wear-resistant steel plates "ABREX" for the heavily worn bed components. ABREX is a steel plate that offers excellent wear resistance while also considering weldability and bendability. It can be considered for use in the bottom plates, side plates, and tailgates of the beds, and depending on the usage conditions, it may lead to thinning and weight reduction. At Kumagai Special Steel, we offer consultations tailored to the specifications of your vehicle, from cutting plates to bending, hole drilling, and welding fabrication.

For the screens of the crushing plant and wear protection for the chutes where crushed stone continues to flow. Streamlining equipment maintenance with replacement liners.
The chutes in a crushed stone plant are equipment that tends to experience localized wear due to the continuous falling and sliding of hard crushed stones. The reduction in plate thickness and the formation of holes due to wear can lead to repair work and line stoppages. We propose the wear-resistant steel plate "ABREX" as a replaceable liner to protect the chute body. Additionally, in a crushed stone plant, the screens for soil and sand are also areas that are prone to wear. We similarly recommend the wear-resistant steel plate "ABREX" for these as well. By placing ABREX-made screens and liners in screen components and the inner surfaces of chutes, it is possible to protect the base material from wear, thereby extending the lifespan of the equipment and reducing maintenance burdens. It is important to consider the type of steel, plate thickness, and segmentation method according to the locations where wear is concentrated, the particle size of the crushed stone, the height of the drop, and the processing volume. Kumagai Special Steel can accommodate cutting, drilling, bending, and welding fabrication based on provided drawings.
Considering the thinning and lightweighting of crane structural members with high strength and toughness.
Cranes are required to minimize the weight of components such as booms and outriggers while ensuring lifting capacity. While increasing the thickness of materials can make it easier to secure strength, the increase in overall weight can affect workability and transportability. We propose Nippon Steel's welded structural high-strength steel plate "WEL-TEN" for structural components that consider both strength and weight reduction. WEL-TEN is a high-strength steel plate that possesses high tensile strength and notch toughness, suitable for use in welded structures. By reviewing the plate thickness within the range that meets the required strength, it may lead to a reduction in the weight of structural components. Nippon Steel's technical documentation also indicates that high-strength steel is required for crane booms and outriggers.
