  42CrMo4 Alloy Steel Bars Manufacturers and Suppliers Medium carbon steels are high strength steels which include 42CrMo4 as an important member in low alloy category. These steels show positive response to all variety of heat treatments. 42CrMo4 is a 1% chromium – molybdenum medium hardenability general purpose high tensile steel – generally  supplied hardened and tempered in the tensile range of 850 – 1000 Mpa (condition T). 42CrMo4 alloy is a high quality, high tensile alloy steel usually supplied readily machineable in ‘T’ condition, giving good ductility and shock resisting properties combined with resistance to wear.   What is 42CrMo4 Steel?

 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 ...

  Hard chromed bar is a chromium-plated steel product used primarily as piston rod material in all standard applications in hydraulics and pneumatics. Common applications are found in cranes, dump trucks, lifters, garbage compactors, agricultural machinery and production equipment with movable sections. Because hard chromed bar is normally used in conditions of high stress, friction and harsh climatic environment, the quality of the base metal and surface treatment are of paramount importance. Wear, impact and corrosion resistance, as well as high yield strength, surface smoothness and uniform quality are most important properties of hard chrome bar. The basic grades of steel used in the hydraulic filed are 1045, 4140 hardened and tempered,1045 induction hardened. Grade 1045 induction hardened chrome steel bar is primarily used in hard chrome bar manufacture due to its wide range of properties consistent with end use applications. Grade 4140 is used in applications where greater y...

  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...

  4140 chrome plated steel bar , which is a specific type of   hard chrome rod , because the material is 4140 steel, so this kind of hard chrome rod is called 4140 chrome plated steel bar. The familiarity and understanding of this product is to use the product correctly and reasonably, and further, it can have a good use effect on the use of the product. 4140 chrome plated steel bar, the product quality should meet the requirements, the specific is: the use of quality and good performance materials for manufacturing to ensure that the product has good performance and use. The product should be simple and convenient to use, and it is not easy to cause problems during use, and it is not easy to be damaged or damaged, so as to avoid frequent replacement of new ones and increase cost.

 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.

42CrMo4  (EN 10083-3)   is the most commonly used quenched and tempered steel because of its high property/cost relationship. It has high hardenability, good heat resistance, excellent forging and machine tool cutting. Surface hardening or nitriding can improve wear resistance and fatigue strength. Hardened, tempered and nitrided gears can be substituted for surface hardened and hardened gears if they do not yield to excessive pressure.
