hay algunos kits de palieres para el D35 que hablan de "1541H alloy Steel".. es bueno?

Stock axle shafts are typically made from 1040 and 1541 steel and are perfectly adequate for stock applications. For performance axle shafts, we use 1541H steel, 4140 and 4340 Chromoly steel, which has been hardened to maximize the strength and ductility of the axle shafts.
1541 is a plain high carbon steel similar to 1040 but with added manganese for better hardenability, but there is not enough alloying elements in it to be classified as an “alloy” steel. 1040 and 1541 are used by manufacturers as a cheap alternative in meeting requirements for stock axles; they heat treat 1040 and 1541 by induction hardening, which is a production form of case hardening. It is fast, cheap and works very well. 1541 is able to be hardened to a greater depth (better hardenability) than 1040/1050 and is therefore stronger.
4140 and 4340 are true alloy steels. 4140 is alloyed with chromium, molybdenum and 4340 with chromium, molybdenum and nickel. 300M is also called 4340 modified, as it is basically 4340 with silicon added. The strength of steel is generally directly related to the hardness. The harder you can get the steel, the stronger it is (tensile strength), but you generally loose toughness. These alloys give the steel increased hardenability and reliable toughness at higher hardness/strength levels. They can be induction hardened but their purpose and advantage is that they can be thru hardened, due of their better hardenability. 4340 has better hardenability than 4140 so it can be heat treaded harder, and thus stronger, than 4140. The 4140 and 4340 material is available in commercial and aircraft quality. Aircraft quality is achieved by vacuum melting to minimize impurities and is a more costly endeavor. Most 4140 and 4340 axles are made of commercial quality steel.
