Three Key Factors to Understand Machinability of Carbon and Alloy Steel
Cold Work, Thermal Treatments, and Chemical Composition are three major determinants of the machinability of steel.

Killed Steel
Steel is killed to improve its soundness and internal structure. Silicon, Aluminum, Niobium, Vanadium, and sometimes Manganese are added to scavenge oxygen in the molten steel.

The Difference Between Microalloy And Regular Alloy Steels
Since microalloyed steels are able to get higher properties using forging process heat- rather than an additional heating quenching tempering cycle- they can be less expensive to process to get improved mechanical properties. The microalloyed microstructure of either ferrite pearlite or bainite is less abrasive than that of a fully quench and tempered alloy steel.

5 Ways Fine Austenitic Grain Size Affects Your Machine Shop
While Austenitic Grain Size is a result of chemistry (composition), the changes that it evokes in our process are a result of material structure and properties, not just the chemical ‘ingredients.’ Steel that is fully deoxidized and grain refined is more sound, less suseceptible to cracking and distorting, and more easily controlled in heat treat. Well worth it in final performance compared to the machinist’s increased tooling costs.
