AISI 4140 steel grade is a versatile steel grade. 4140 material is widely used in a lots of industrial fields. It is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. ASTM 4140 chrome-molybdenum steel can be oil hardened to a relatively high level 4130 Alloy Steel Bar and Tube Dynamic Metals Ltd4130 Alloy Steel Bars and Tubing 4130 Alloy Steel Bar & Tube 4130 is a through hardening low alloy steel containing molybdenum and chromium as strengthening agents. 4130 responds well to nitriding for very good wear and abrasion resistance.
Chromoly 4130 is a low alloy steel containing chromium, molybdenum, iron, carbon, and other alloying elements. The addition of chromium to steel improves strength and corrosion resistance and the molybdenum increases material toughness. 4130 chromoly tubing also has a smooth interior and exterior finish that resists scaling and oxidation. 4130 and 4140 heat treat and filler - Welding4130 and 4140 heat treat and filler. by David (NC Charlotte) Hello I have a piece of 4130 that I want to weld to 4140. what filler should I use and what gas (mix or pure argon) both parts are over an inch thick and will require a preheat. I'm assuming 400+ degrees (f). 4130h steel properties4130 Steel Bar Stock Alloy Bar TWs cold drawn seamless 4130 alloy steel bar, rod, and wire is a lighter weight, higher strength alternative to carbon steel. As the market leader in 4130 alloy steel, TW Metals delivers a full range of 4130 round bar. MatWeb - The Online Materials Information Resource.
Jun 08, 2017 · 4140 Steel Applications. There are many 4140 steel applications and when navigating your way to finding a new metal machining carrier/partner, it can be difficult to grasp just whats out there. What types of metal rods, bars, and tubing are best suited for 4140 cracking issue - Heat Treating, general discussion Jun 13, 2012 · One thing that is stated by most other steel suppliers is to avoid where possible tempering 4140 in the regions between approx 200degC and 450/475degC (392F to 887F) as 4140 and also 4340 have a tendancy to lose ductility and become temper brittle in these ranges. Interlloy recomends 550degC to 700degC anyway, does not mention lower temps AISI 4130 Alloy Steel (UNS G41300) - AZoMAISI 4130 steel can be annealed at 843°C (1550°F) followed by air cooling at 482°C (900°F). Tempering of AISI 4130 steel can be performed at 399 to 566°C (750 to 1050°F), depending on the desired strength level. Hardening of AISI 4130 steel can be done with cold working or heat treatment.
Heat Treatment - AISI 4130 steel is heated at 871°C (1600°F) and then quenched in oil. This steel is usually heat-treated at temperatures ranging from 899 to 927°C (1650 to 1700°F). Forging of AISI 4130 steel can be performed at 954 to 1204°C (1750 to 2200°F). Hot working of AISI 4130 steel can be done at 816 to 1093°C (1500 to 2000°F). AISI 4130 Steel 25CrMo4 1.7218 708A25 SCM430 What is 4130 Steel? AISI 4130 alloy steel is a medium carbon, low alloy steel in ASTM A29 standard. ASTM 4140 steel is also commonly referred to as a chromoly steel, or chrome moly steel, containing nominally 0.28-0.33% Carbon, 0.8-1.1% Chromium and 0.15-0.25% Molybdenum. It is similar to 4140 steel which has a higher carbon level Alloy Steel 4120 - Continental Steel & Tube CompanyAlloy Steel 4120, also sold as SAE/AISI 4120, is a chromium-molybdenum structural alloy steel. This case-hardened alloy offers users good strength, toughness, and wear-resistance. Leaders in a wide variety of industries, including aerospace, oil and gas, automotive, agricultural and defense, rely on Alloy Steel 4120 for critical products and parts such as:Piston pins Crankshafts 
Alloy Steel Sheet/Plate 4130 is highly versatile and used for a wide range of applications including automotive, aerospace, bicyling, construction, and firearm projects. 4130 steel offers good strength, weldability, impact and abrasion resistance while also being easy to machine. 4130 steel sheet/plate stock is available in full size and custom cut lengths.
