Granulado de aço cortado
Steel cut wire is produced from recycled steel wires, such as bead wires and steel ropes, which are cut into granules using specialized cutting machines. This ensures consistent quality and durability for demanding blasting applications.
Compared with standard steel shots, cut wire features higher hardness, often exceeding 50 HRC. With advanced rounding processes, it can also be transformed into spherical cut shots, offering superior blasting performance and longer service life.
Detalhes do produto
A granalha de fio de aço cortado é fabricada por meio do corte de fios de aço de alta qualidade em grânulos uniformes. Dependendo do processo de produção, ela pode ser fornecida em dois formatos principais: fio cortado cilíndrico e fio cortado esférico (granalha arredondada). Por meio de uma tecnologia avançada de arredondamento, as arestas de corte são eliminadas, produzindo uma granalha lisa e durável.
Características
Alta dureza – Normalmente acima de 50 HRC, muito mais dura do que os grãos de aço fundido convencionais, garantindo um desempenho agressivo na jateamento.
Durabilidade e longa vida útil – A microestrutura uniforme e a excelente resistência à fadiga garantem uma vida útil mais longa.
Formato consistente – Disponível nas formas cilíndrica e esférica, garantindo uma qualidade de jateamento estável.
Gama de tamanhos – Tamanhos padrão de CW1,0 mm a CW3,0 mm, com tamanhos personalizados disponíveis mediante solicitação.

Aplicações do produto
Steel cut wires are produced from national standard bead wires and are widely applied in machinery, automotive, shipbuilding, steel structure, pipeline industries, and other manufacturing sectors for surface cleaning and strengthening of workpieces. During shot blasting, the cut wire shots are propelled at high speed by the blasting machine in a parabolic trajectory, effectively removing rust and oxide layers from the product surface while achieving the required finish and surface roughness. Among the available sizes, CW1.5mm is the most commonly used, with hardness typically exceeding 50HRC.
Due to their higher hardness, usually above 50HRC, steel cut wire shots can sometimes cause scuffing on softer materials, particularly those with hardness below 48HRC. For this reason, it is often recommended to mix steel cut wire shots with steel shots or steel grits of similar size for shot blasting. In practice, some customers also mix low-carbon steel shots with steel cut wire shots, which has proven to deliver excellent blasting results.
