 As we all know , 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 AISI 4140 chrome bars . In this case the chromium overlay receives a better support by the hardened base material and is, therefore, less delicate. Why Induction Hardening? Our controlled induction hardening process ensures: Targeted Hardening: Only the working surface is hardened (HRC 58-62), preserving core ductility. Uniform Case Depth: Precise electromagnetic induction achieves consistent case depth (0.8–1.2 mm), mitigating distortion risks. Thermal Efficiency: Faster than traditional furnaces, with minimal decarburization. The Technical of AISI 4140 Chrome bars Material Composition & Performance. 4140 Alloy Steel: A chromium-molybdenum steel (0.75–1.00% Cr, 0.15–0.30% Mo) offering exceptional tensile strength (≥980 MPa) and torsional rigidity. Chrome Plating: A 50-100 µm thick chr...

  4140 Steel Applications There are many SAE 4140 steel applications and when navigating your way to finding a new metal machining carrier/partner, it can be difficult to grasp just what’s out there. What types of metal rods , bars, and tubing are best suited for your facility, and what materials you should be using? SAE 4140 steel is widely used in many industrial fields for its strength and versatility, and therefore is important to know about it if you are considering using it in your facility. Here is an outline of its key characteristics and most common applications. What is SAE 4140 Steel? SAE 4140 steel is a low-alloy steel containing chromium and molybdenum as strengthening agents. These give great corrosion resistance and strength up to around 600°. These characteristics include high strength and good machinability that can easily be heat treated for increased hardness. 4140 Steel Composition Chromium, Cr 0.80 – 1.10 Manganese, Mn 0.75 – 1.0 Carbon, C 0.380 – 0.430 Silic...
