Both 1040 and 1045 steels are popular at Capital Steel & Wire, and both have different chemical and mechanical characteristics. These also help determine different applications for both grades of steel. Chemical Makeup To see differences in chemical characteristics of 1040 and 1045 it is best to do a side by side comparrison.
1045 is a medium-carbon steel, made with 0.45% carbon. Medium-carbon steels are stronger than low-carbon steels, but not as easy to weld, and can be tempered by quenching.
The 10XX (1045, 1095) Steels - 1095 is the most common 10XX steel (or "high carbon" steel) used for knife blades. Steel in the range 1045-1095 are used for knife blades, although 1050 is more commonly seen in swords. 1045 steel has less carbon (.45%), where 1095 has more (.95%), inversely 1095 has less manganese and 1045 has more.
Consequentially, 1060 Carbon Steel swords are very popular, though because the steel is harder than 1045 - 1060 Carbon steel swords are more difficult and tume consuming to forge, shape and polish. And thus almost always has a higher price tag that 1045 - typically between $150 to $500 depending on fittings, type of tempering, polish, etc.
SAE-AISI 1045 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. We are renowned AISI 1045 steel stockholders and suppliers, delivering to the whole of India and worldwide.
The austenitizing temperature for SAE 1045 induction hardening carbon steel is 800-845 C. Full Annealing. The annealing temperature for AISI 1045 carbon steel is from 790-870 C, cooling cycle from 790 to 650 C at a rate of 28 C/h in furnace, and can get the HBW hardness range from 156 to 217. (Suitable for forgings with a section thickness of up to 75 mm.
