41xx steel is a 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, cro-moly, CrMo, CRMO, CR-MOLY, and similar).

2020年8月12日 · 4130 steel is a low-carbon, chromium-molybdenum alloy of steel known for strength, toughness, and versatility. It has a density of 7.85 g/cm 3 (0.284 lb/in 3). 4130 steel responds well to heat treatment, which can significantly enhance its hardness and strength.

The below table outlines the material properties for Chromium Molybdenum Steel (Alloy 41XX) material including the young's modulus, yield strength, ultimate strength and other relevant mechanical properties required for structural and mechanical design.

Chromoly falls under the AISI 41xx steel designations (ASTM A519). Examples of applications for 4130, 4140, and 4145 include structural tubing, bicycle frames, crankshafts, chain links, drill collars, gas bottles for transporting pressurized gases, firearm parts, clutch and flywheel components, and roll cages.

41xx steel or Chromoly steels are steels containing chromium and molybdenum. Therefore, they are tougher and stronger than regular steel. The two steel variants we are comparing, i.e., 4140 vs 4130 steel, fall under the general classification of 41xx steel and others such as the 4340 steel.

41xx 钢或铬钼钢是含有铬和钼的钢。 因此，它们比普通钢更坚韧。 我们比较的两种钢种，即 4140 和 4130 钢，属于 41xx 钢和其他钢（例如 4340 钢）的一般分类。 41xx 类别下的钢的成分中含有铬。 然而，它的数量不足以赋予它们在不锈钢中看到的防锈性能。 然而，它们比普通钢更坚固。 什么是 4140 钢？ 4140 钢是一种铬钼钢变体，其最大碳含量为 0.38% – 0.43% 以及锰、磷、硫、硅、铬和钼等其他元素。 它是低合金钢。 然而，它坚固、坚韧且可加工。 4140 钢由于其特 …

Brinell hardness of low-alloy steel – 41xx steel – chromoly steel is approximately 200 MPa. In materials science, hardness is the ability to withstand surface indentation (localized plastic deformation) and scratching.
