When fully annealed, melt extract stainless steel fibers are more pliable and ductile. They not only allow for more user-friendly than the stiff cut fibers, but also have better flow features. It is especially characterized by thermal shock resistance, steep thermal gradients resistance and mechanical shock resistance, minimizing damage and delaying failure caused by cracking. Thanks to their optimum aspect radio, rapid fiber separation during the mixing phase are better guaranteed.
