Steel material selection for liners, chutes, and wear components in high-temperature environments.
SB480 and other SB materials, Mo-added SB materials, SCMV materials, heat-resistant stainless steel, etc.
Wear-resistant steel also softens with temperature rise. Check the wear amount and the actual steel temperature separately.
In liners, chutes, and screens where hot materials or products come into contact, in addition to wear, the reduction in hardness and strength due to high temperatures becomes a problem. Even steel plates that excel in wear resistance at room temperature may soften if the operating temperature rises, so it is not always possible to simply select standard wear-resistant steel. Generally, standard wear-resistant steel is often assumed to be used below 300°C, and specialized grades that suppress softening are candidates for temperatures around 300 to 450°C. However, the required performance varies depending on the mode of wear, impact, temperature distribution, and holding time. Areas prioritizing wear resistance are separated from support structures prioritizing high-temperature strength, allowing for the selective use of wear-resistant steel, alloy steel, and heat-resistant steel.

| Model number | overview |
|---|---|
| SB480 (carbon steel plate with high strength (480-620 MPa grade)) | Selected for conditions with high design loads and pressures. As strength increases, attention to welding conditions and processing management becomes important. |
| JIS G4109 SCMV material | It is a low-alloy heat-resistant steel used in high-temperature and high-pressure environments, such as boilers in thermal power plants and desulfurization reaction towers in oil refining plants. It demonstrates excellent high-temperature strength and environmental resistance in the temperature range of approximately 350°C to 600°C, exceeding the usage limit of carbon steel (around 350°C to 400°C). |
| JIS G4312 SUS310S-HR | It is a fully austenitic heat-resistant stainless steel of the 25Cr-20Ni system. It boasts significantly higher oxidation resistance and high-temperature creep strength compared to general-purpose austenitic steels (such as SUS304), and can be used in atmospheric (oxidizing environment) conditions without structural stresses other than its own weight to prevent oxidative wear, with a maximum usage temperature of 1,100°C to 1,150°C (although measures against deflection due to its own weight are necessary). |
| JIS G4902 NCF800HP | This is a Fe-Ni-Cr-based austenitic heat-resistant superalloy equivalent to Alloy 800H (UNS N08810) according to U.S. standards. It exhibits excellent high-temperature strength, carburization resistance, and oxidation resistance in the high-temperature creep range (approximately 600°C to over 900°C), exceeding the service limits of stainless steels (such as SUS310S), and is applied to critical components in petrochemical plant cracking furnaces, reforming furnaces, power plants, and nuclear-related equipment. |
