 Based on the SAE (Society of Automotive Engineers), steels that have a naming structure of 41XX are informally known as chromoly steel, or it is a chromium-molybdenum steel. These steels are usually much harder and tougher than normal carbon steel. Alloying elements allow the steel to be heat treated to obtain stronger physical properties. The last two digits are how much carbon is in the steel. In the case of 4140 , there is .40% carbon and 4150 has a .50% carbon content. These are both extra strong and hard alloys of steel, and are used in applications requiring higher performance than carbon steels can typically withstand. DIFFERENCES Tensile strength: 4150 has a higher tensile strength, meaning it has a higher threshold for stress before breaking. Ductility & workability: 4140 is more ductile, meaning it can be bent easier than 4150. It also can be used in cold working conditions while 4150 needs to be thermally treated before forming. WHEN TO USE These types of steel ...

  4140 Quenched & Tempered Chrome Shafting is a kind of steel shafting by Quench & Tempered, Stress Relieved Through Hardened Alloy steel shaft with excellent mechanical properties. 4140 Q&T is a steel in the family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, CrMo, CRMO, CR-MOLY, and similar). They have an excellent strength to weight ratio and are considerably stronger and harder than standard 1020 steel, but are not easily welded (need pre and post weld thermal treatment to avoid cold cracking). While these grades of steel do contain chromium, it is not in great enough quantities to provide the corrosion resistance found in stainless steel. The Quenching process hardens the steel, while the Tempering process restores some of the ductility and remove...

  42CrMo4 chrome plated bar is manufactured from low-alloy chromium-molybdenum steel and supported by an induction hardened case offering greater strength and resistance to mechanical damage from external impact. It is used in applications requiring greater yield strength in combination with greater surface impact resistance. The piston rod material 42CrMo4 hardened and hard chrome plated with the material number 1.7225 is suitable for heavy use and is especially wear-resistant thanks to its hardened surface layer with a surface hardness of 56–64 HRC. Due to the material's high stability very high forces can be transmitted, e.g. for small connecting threads with large piston rods. Hard chrome plating means that an especially thick chrome layer is applied after the pre-honing and before finishing the honing process. The layer thickness depends on the rod diameter and has a hardness of more than 800 HV. Hard chrome plated piston rods can be used between -15°C and 200°C. Applica...

 When the specific pressure in service is very high or there is a risk to damage the chromium plated surface by shocks or abrasions, it is advisable to use the induction hardened chrome plated bar . In this case the chromium overlay receives a better support by the hardened base material and is, therefore, less delicate. For the piston rod of a hydraulic cylinder, a hardness of 54-55 HRC (HV 577-613) for the surface lying under the chromium overlay is enough. These hardness values are reachable with steel grades like UNI C43 or DIN Ck45. In case of very high specific pressure as the one met with ball bearing systems like Ball Bushing, it is necessary that the hardness reaches 60 HRC (HV 697). In this case a steel grade like SAE4140, which gives HV 700-750, has to be chosen. For rods subjected to high mechanical stresses and for which the impact strength is important, the quenched and tempered steel grade 42CrMo4 (SAE 4140) induction hardened, is requested. 4140 induction hardened...

 AISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components, like axles, shafts, bolts, gears and hydraulic applications. Similar to alloy grade AISI 4130 chrome moly alloy steel but with a slightly higher carbon content. The higher carbon content of AISI 4140 steel gives greater strength and heat treatment capabilities in comparison to AISI / ASTM 4130 alloy steels, however it does have inferior weldability characteristics.
