1. For the specific cutting of steels, up to 6mm material thickness, then we recommend your metal cutting guillotine blades are manufactured from Grade D2 material, hardened and tempered to 57/58 Rockweld to give an abrasion resistance, to increases periods between regrinds.

Please Note* Because of the hardness, of 57/58 Rockweld, if you then cut stainless steel or durbar, or any other high tensile strength steel with these blades, you are risking chipping of the blades.

2. For the specific cutting of Stainless Steels.
Stainless steel has a higher tensile strength than the commonly used carbon steel BS EN 10025:1993 – S275, it is this increased tensile strength with Stainless steels that creates the problem of blades chipping.To attempt to reduce metal cutting guillotine blade chipping, a lower hardened and tempered figure of  55/56 Rockweld is used, however, abrasion resistance is sacrificed, these blades will require frequent resharpening

So, there is no magic solution to blade choice when cutting varied metals

Harden and temper guillotine blades to 57/58 Rockweld increases abrasion resistance, increases periods between regrinds, but the blade is more likely to chip when cutting stainless steel, durbar or high tensile steels. Harden and temper blades to Rockweld 55/56, then chipping is less of a problem, but abrasion resistance is reduced,  shorter periods between blade regrinds are experienced.

3.) For the cutting of mixed carbon steels, stainless steel, durbar, high tensile strength steel above 6mm material thickness, then we recommend your metal cutting guillotine blades are manufactured from ‘Grade 2631 shock-resistant steel’ hardened and tempered to 57/58 Rockweld [ chipper quality ]

But again these shock-resistant guillotine blades have a downside, this being that this grade of steel quickly loses its crisp sharpness, therefore whilst your metal cutting guillotines cutting capacity range indicates that you can go down to 22swg or 18swg etc,
the lack of a good crisp sharp edge may prove to make the guillotine not suitable for cutting of such thinner materials
