Know how to ensure that steel can be moulded? Here are the best methods

One of the most common ways of processing steel in the industrial environment is moulding, but the material can often break during the process. How can you avoid downtime, and the resulting cost?

Also in this case, as with other processes such as welding, it’s first of all important to know which parameters and technical characteristics make a material suitable for a specific process.

When buying steel, it’s important to specify how the material is going to be used, and which processes it will be subjected to.

Pre-analysis of a sample of the material is always the best way to be certain that its quality meets our needs. This test can be done quickly, also at the SANGOI workshop, simply by subjecting a sample of the material to a tensile test.

The mechanical characteristics you need to observe include:

  1. extension (A80%)
  2. the anisotropy coefficient (r90)
  3. hardenability (n90)
  4. The healed limit (Re) or, more commonly with moulding materials, the maximum deviation from proportionality at 0.2% (Rp 0.2%)
  5. The breaking load (Rm)

In particular, given the conformity to the required quality of the other characteristics, the n90 and r90 values are characteristic of materials which are suitable for moulding.

How about some reference tables, which can give you information about the different quality grades of a material, and its mouldability?
