AISI 4130 Cr-Mo Steel (30CrMo)
AISI 4130 Cr-Mo steel is a low alloyed steel used in a variety of applications and industries. It contains elements such as chromium and molybdenum, which adds strength and hardenability to the material, making it suitable for applications requiring extreme hardness and wear resistance.
It is a popular material for automotive components, aircraft parts and oil and gas exploration tools due to its light weight, good corrosion resistance and toughness. It is also used in a variety of fastener and structural applications, including nuts, bolts, bolts and screws, and in forged parts, springs and pins. It is also used in machine tool components, forging dies and many other machine parts.
AISI 4130 Cr-Mo steel is well known for its very high strength, good weldability, and excellent machinability. It is an excellent alternative to stainless steel and other high alloy steels due to its ability to be used with cast iron, stainless steel and titanium. Its good fatigue strength makes it suitable in various industries, including oil and gas production, aerospace, defense and construction.
The characteristics of AISI 4130 Cr-Mo steel are determined by its composition, which is made up of 0.30% carbon, 0.25 to 0.45% manganese, 0.80 to 1.10% chromium, 0.15 to 0.25% molybdenum and 0.04 to 0.06% phosphorus. It also contains less than 0.15% sulfur and 0.40 to 0.65% silicon. It has a melting point range between 2600°F and 2790°F and an ultimate tensile strength of 95,000 psi.
AISI 4130 Cr-Mo steel is easy to weld with either gas or arc welding processes. It has a weldability rating of AISI 3, which means it can be joined to itself or other metals with minimal pre-heat and post weld treatment steps. It has excellent machinability and is suitable for operations such as boring, drilling, reaming and tapping.
AISI 4130 Cr-Mo steel is a versatile and cost effective material. It is used in a variety of applications, including automotive components, fasteners, structural components and oil and gas exploration tools. It is also used in many machine parts, such as forging dies and machine tool components, due to its superior strength and wear resistance. It is suitable for a variety of heat treat processes, including annealing, hardening and tempering, to optimize its properties. It is an excellent choice for applications that require superior strength and wear resistance, as well as good weldability and machinability.
