The Reason Metals Need To Be Hardened And Tempered For Higher Quality
Hardened & Tempered For Higher Quality Metals need to be hardened for an improvement in their mechanical properties, as well as an increase in the level of hardness, producing a tougher, sturdier item. Alloys are heated above the critical transformation temperature for the material, then cooled rapidly enough to cause the soft initial material to transform to a much … Read more
