Acier à outils S7
L'acier S7 est une sorte d'acier à outils trempé à l'air ou à l'huile avec une ténacité élevée aux chocs. La combinaison de résistance et de ténacité élevée en fait un candidat pour diverses applications d'outils.
L'acier à outils S7 est souvent utilisé pour les outils de travail à froid qui doivent résister à des charges d'impact et d'impact élevées, tels que les lames de cisaillement, les matrices de forgeage, les matrices de serrage, les burins et les poinçons.

S7 is impact resistant tool steel, which can be used as punching or punching tools, shear dies, hot forging dies, die casting dies of fusible alloys, and blades for hot and cold metal shearing.
S7 STEEL CHARACTERISTICS
S7 steel is a high-quality chromium molybdenum alloy tool steel with many excellent characteristics. As a type of steel with high hardness and wear resistance, S7 steel has been widely used in many fields.
Firstly, S7 steel has excellent hardenability. This enables it to quickly achieve the required hardness and strength during the heat treatment process, and has high toughness. This hardenability makes S7 steel an ideal choice for manufacturing various cutting tools, punches, and molds. Whether used for cutting, stamping, or forming, S7 steel can provide excellent performance and durability.
Secondly, S7 steel has high strength and tempering stability. It has high tensile strength and yield strength, and can maintain its strength and hardness even in high temperature environments. This makes S7 steel very useful in manufacturing tools that need to withstand high loads and impacts. Whether used as cutting tools for heavy-duty machinery or high-strength parts in automotive manufacturing, S7 steel can provide excellent performance.
In addition, S7 steel also has high impact toughness and wear resistance. Its toughness makes it less prone to fracture or deformation when subjected to impact, thereby extending its service life. Meanwhile, the surface of S7 steel has good wear resistance, enabling it to maintain good performance in high-speed cutting and wear environments. This makes S7 steel an ideal choice for manufacturing cutting tools, punches, and molds.
In addition, S7 steel also exhibits high hardening and softening resistance. Its hardness can be precisely controlled during the heat treatment process to meet different application requirements. This makes S7 steel very suitable for manufacturing tools that require specific hardness and strength. At the same time, S7 steel also has excellent softening resistance, which can maintain its hardness and strength even at high temperatures, thereby extending its service life.
In addition, S7 steel also exhibits excellent mechanical fatigue resistance. It can maintain stable performance under repeated loads and is less prone to fatigue fracture. This gives S7 steel a great advantage in manufacturing tools and parts that require long-term use. Whether used as cutting tools for mechanical equipment or key components of automotive engines, S7 steel can provide reliable performance.
Finally, S7 steel also possesses high toughness and medium temperature oxidation resistance. Its toughness makes it less prone to fracture or deformation under impact, providing a longer service life. At the same time, S7 steel has good oxidation resistance in the medium temperature range and can resist the influence of oxidation corrosion. This makes S7 steel not only suitable for manufacturing tools and dies that work at higher temperatures, but also for manufacturing parts that are used at moderate temperatures.
