SAE/AISI 52100 steel is an alloy steel occupying a central position in the field of materials science and engineering, particularly in the manufacture of precision mechanical components. It is considered the classic rolling bearing steel, and the comprehensive properties of 52100 steel serve as the benchmark against which the composition of other similar steels is […]

S7 tool steel is an impact-resistant tool steel. Its greatest advantage is exceptional impact resistance. A characteristic of S7 steel is its “air-hardening” capability. After heat treatment, it can be hardened by cooling naturally in air, rather than requiring immersion in oil or water. S7 exhibits excellent dimensional stability during machining, resisting deformation or cracking.

When manufacturing cold-working tools, selecting the right steel is paramount to determining tool life and efficiency. An ideal tool steel must possess high wear resistance, sufficient toughness, and excellent dimensional stability.  A2, D2, and D3 are the three most commonly used and representative grades of steel. Each of these steels represents a distinct “trade-off” in

Tool steels are a specialized category of iron-based alloys designed specifically for manufacturing tools, dies, and stamping dies used to cut, form, or shape other materials. A common characteristic of these steels is their ability to achieve extremely high hardness, strength, toughness, and outstanding wear resistance through specialized heat treatment processes. Among numerous critical engineering

Air-hardening steel is a critically important category of tool steel in materials engineering. Its widespread application stems from its minimal distortion during heat treatment, excellent deep hardenability, and superior mechanical properties. Air-hardening steels, such as the A and H series, rely on air-cooling—a relatively mild method—to achieve a hard martensitic structure. This stands in stark

Welding, forming, and heat treatment exert profound and interrelated effects on the microstructure, mechanical properties, and overall performance of tool steel during manufacturing. These processes determine the strength, hardness, toughness, ductility, and corrosion resistance of tool steel, while also influencing the presence of detrimental factors such as residual stresses and deformation. Whether tool steel can

AISI A2 tool steel is an air-hardening medium-alloy cold-work tool steel that is widely used, offering a favorable balance between wear resistance and toughness. Currently one of the most popular tool steels in the United States, it is commonly employed in high-precision tool manufacturing, such as gauges, precision measuring instruments, and complex dies for forming,

O aço para ferramentas AISI D2 é um aço com alto teor de carbono e alto teor de cromo que serve como base para inúmeras aplicações industriais exigentes. Com sua excepcional resistência ao desgaste, alta dureza e estabilidade dimensional, o D2 é o material de escolha para matrizes de longa duração, ferramentas de corte, conformação, laminação de roscas, estampagem profunda e cisalhamento. No entanto, ao mesmo tempo em que aumenta a dureza do aço D2

Temperaturas e pressões extremas encontradas em aplicações de trabalho a quente, como forjamento, fundição sob pressão e extrusão, representam desafios significativos para os aços para ferramentas, frequentemente levando a falhas por desgaste, deformação plástica e fadiga térmica. Selecionar aços para ferramentas que mantenham o desempenho sob condições severas e evitem falhas prematuras é crucial para alcançar uma produção eficiente e econômica.

O aço para ferramentas P20 encontra ampla aplicação na fabricação de moldes e fundição sob pressão. Este aço de baixa liga é normalmente fornecido pré-endurecido (dureza de aproximadamente 30-40 HRC), permitindo a usinagem direta em moldes complexos sem tratamento térmico adicional em alta temperatura, minimizando assim a deformação e as alterações dimensionais. Oferece excelente usinabilidade, polibilidade e resistência ao desgaste. As principais aplicações incluem plásticos.
