An Introduction to Mild and High Strength Low Alloy HSLA

Nov 28, 2018 · Mild steel can be transformed into high-strength low-alloy (HSLA) steel with the addition of a few alloys such as phosphorus, sulfur, silicone and molybdenum. HSLA boasts high strength, good machinability, and ductility, but significantly lower weight as compared to Aquamarine Value, Price, and Information - Gem In fact, cut aquamarines over 25 carats will have a lower price per carat than smaller stones of the same quality. Setting and wearing stones of that size can be difficult, so theres less demand for them. Aquamarine prices depend on depth and purity of color and clarity.
