High speed steel is a kind of high alloy steel containing a variety of elements, heat treatment has high hot hardness, high speed steel outer diameter is also a variety of kinds, there are 250mm, 300mm, 350mm, 375mm, these conventional specifications have, cutting materials are different, naturally in the choice of material.
It should be noted here that M42 is a relatively good material in China, more suitable for 304 high hardness stainless steel material, M2 is an imported material name, some pursue durability, pay attention to the cutting surface can choose M2, its unit price is relatively high, but compared with some domestic materials, he still has advantages. Therefore, in the selection of circular saw blades, it is necessary to combine the materials and requirements of its own cutting, targeted selection, in order to achieve twice the effect with half the effort.
