Tag: Shearing Effects of Punching and Shearing

Punching holes and shearing during fabrication are cold-working operations that can cause brittle failure. Bolt holes, for example, may be formed by drilling, punching, or punching followed by reaming. Drilling is preferable to punching, because punching drastically cold-works the material at the edge of a hole. This makes the steel less ductile and raises the transition temperature. The degree of embrittlement depends on type of

Steel shops are commonly organized into departments such as receiving, detail material, main material cut-and-preparation, assembly and shipping. Many shops also have paint departments. Material is received on trucks or by rail, off loaded, compared to order requirements, and stored by project or by size and grade. Material is received from the mill or warehouse marked with the size, specification, grade, and heat

Tag: Shearing Effects of Punching Holes and Shearing

Excessive cold working of exposed edges of structural-steel members can cause and cracking and should be avoided. Punching holes and shearing during fabrication are cold-working operations that can cause brittle failure in thick material. Bolt holes, for example, may be formed by drilling, punching, or punching followed by reaming. Drilling is preferable to punching, because punching drastically coldworks the material
