AISI SAE 8620 Steel (UNS G86200) AISI SAE 8620 steel is a commonly used low-alloy material for carburizing, with excellent carburizing response, good hardenability for most section sizes, it has many extensive applications due to its low cost, better machinability, and availability.
Carbon Steel Question:5160 vs. 1060 BladeForumsApr 26, 2009 · 1060 is a simple carbon steel, and 5160 is considered an alloy steel. The inclusion of Chromium and silicone make them act very differently. Chromium adds to rust resistance, and makes the steel harder. I think silicone adds to toughness, but I'm not positive without looking it up. 1060 can be quenched in water, and 5160 can't.

When the hardness after normalizing is 170-217 HB, the relative machinability is about 65%. 20Cr steel has good weldability, and generally does not require heat treatment after welding, but parts with a thickness greater than 15mm need to be preheated to 100-150 °C before welding, and tempering heat treatment may not be performed after welding.
High Carbon & Alloy Greer SteelFor strength and hardness, you need high carbon steel. High carbon and alloy steel is strong and up to task. Our high carbon steel is great when you need rigid steel cut to your exacting specifications.

SAE-AISI 5120 (SCr420, G51200) Chromium Steel Among alloy steels, the composition of SAE-AISI 5120 steel is notable for containing comparatively high amounts of manganese (Mn) and chromium (Cr). Manganese is used to improve hardenability, hot workability, and surface quality. There is some loss of ductility and weldability, however.
SAE-AISI 5140 steel is an alloy steel formulated for primary forming into wrought products. 5140 is the designation in both the SAE and AISI systems for this material. G51400 is the UNS number. The properties of SAE-AISI 5140 steel include four common variations. This page shows summary ranges across all of them.
SCr420 Steel AISI 5120 20Cr4 G51200 1.7027 JIS SCr420 alloy Steel is a high quality Quenched and Tempered Alloy Structural steel, It belong to the high quality low carbon,Low alloy chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardness is 28-34 HRc.
Simulation of the Effects of Temperature and Time on Four steel alloys, AISI 8620, AISI 9310, AISI 1018, and AISI 5120, were chosen for this project because they are widely used in the industry. Initially the alloys were carburized and quenched at Bodycote, after which the carbon concentration data was obtained by Optical Emission Spectroscopy (OES).

Steels for Vacuum Carburizing - Industrial Heatingconcentration ensures hardness after hardening within the range of 58-62 HRC. Carbon concentration in the eutectoid point is lowered by alloy additives, in most cases it is lowered by Ti, and then by Mo, W, Si, Cr, Mn, Ni. For comparison, carbon eutectoid concentration in the 5120 steel amounts to 0,72%, and in case of the 8910 steel it is 0,41%.
