Wear-resistant parts "EXEO-SP"

It boasts excellent wear resistance and is ideal for parts that want to minimize surface roughness deterioration due to abrasion.

The EXEO series is a material developed through a composite linked engineering approach that consolidates NACHI's technology, starting with the analysis of the required characteristics of the material, and utilizing alloy design technology and special melting techniques. EXEO-SP boasts excellent wear resistance and is optimal for parts where it is important to suppress surface roughness deterioration due to abrasion. 【Features】 ○ The alloy components are precisely controlled through special melting technology. ○ Thanks to a unique manufacturing method, carbides and alloy components (matrix components) are evenly distributed. ○ It is used as a component that reduces processability and manufacturing costs compared to conventional wear-resistant materials like cemented carbide.

To suppress blade edge chipping.

Dissolved high-speed steel with irregular shapes and fewer quantities is more effective than round and numerous carbide powders!

To suppress edge chipping, it is necessary to control the progression of wear (especially adhesive wear) and the occurrence of chipping from the wear surface. To suppress the progression of wear, high wear resistance is required, and larger carbide dissolving high-speed steel is more effective than smaller carbide powder high-speed steel. "DURO-SP, V5" is a special dissolving high-speed steel that contains a relatively high amount of hard carbide and is suitable for suppressing edge chipping due to its excellent wear resistance. 【Suppressing the progression of wear (especially adhesive wear)】 ■ High wear resistance is required ■ Larger carbide dissolving high-speed steel is more effective than smaller carbide powder high-speed steel *For more details, please refer to the PDF document or feel free to contact us.

低温環境の鋼材選定|SM400B・SM490B/C・SM570

最低使用温度だけでは決まりません。板厚・応力・シャルピー保証・溶接部まで確認

鋼材は温度が下がると強度が上がる一方、伸びや靭性が低下し、塑性変形をほとんど伴わず破断する「脆性破壊」の危険が高まります。寒冷地や低温設備では、引張強さの高低だけでなく、使用時の最低鋼材温度とシャルピー衝撃特性を確認することが重要です。 SM400B・SM490Bは0℃で27 J、SM400C・SM490Cは0℃で47 J、SM570は-5℃で47 Jのシャルピー吸収エネルギーが規定されています。これらは規格上の試験条件であり、その温度まで一律に安全に使用できるという意味ではありません。最低鋼材温度、板厚、応力状態、溶接、衝撃荷重、適用規格を整理し、B材・C材や低温靭性保証鋼を比較します。
