420 Stainless Steel (UNS S42000) by Vulcan Metal Group

Image
Grade 420 stainless steel is high-carbon steel. Chromium is added to a minimum content of 12%. Grade 420 is ductile when annealed and has excellent corrosion resistance when polished or hardened. The following datasheet gives an overview of 420 stainless steel. Chemical Composition Physical Properties Mechanical Properties Thermal Properties Fabrication and Heat Treatment Machinability When annealed, 420 steel is easily machinable. Welding Use welding rods coated with grade 420 metals for high-strength joints. For ductile joints, use grade 309 filler rods. Heat Treatment Annealing:  Heat at 840° to 900°C. Slow furnace cool @ 600°C, then air cool. Process Anneal :  A nneal at 735°C to 785°C. Air cool. Hardening:  Heat at 980°C to 1035°C. Air or oil quench. Temper at 150°C to 370°C for high hardness and good mechanical properties. Applications Grade 420 stainless steel is used in the following applications: Shear blades Needle valves Surgical equipment Cutlery See more..

Four Things to Know About Molybdenum Before You Source Parts

Image
  For a number of applications in aerospace, defense, energy, and medical diagnostics, molybdenum offers an ideal combination of high performance and practicality. Key characteristics include: A melting point of 4753°F (2620°C) and a peak working temperature of about 3565°F (1965°C) Excellent material strength at high temperatures: tensile strength of about 14,000 psi at 2200°F (1200°C), for example. High thermal conductivity: can be quenched from very high temperatures without cracking Low vapor pressure: minimal outgassing even in hard vacuum Low coefficient of thermal expansion (CTE): exceptional dimensional stability for applications involving temperature swings Corrosion resistant: good for harsh environments These properties combine to make molybdenum a good fit for high temperatures, hard vacuums, and applications requiring strong, lightweight metals.  The trade-off is that molybdenum has several pitfalls that can trap the unwary. Let’s take a look at what you need to ...

What is Shielding Alloys?

Soft magnetic shielding alloys are metals that can easily be magnetized. These materials have a high magnetic permeability, giving low reluctance paths for shifting magnetic fields. These properties make soft magnetic shield alloys great shields against static and slowly varying magnetic fields. They’re often used to improve quality in home theaters and to shield sensitive medical and electronic equipment. Materials included in the soft magnetic shield alloy group include the following. High Perm 49 (alloy 48, 49 & 50) HyMu 80 (alloy 79) By redirecting a magnetic field, magnetic shielding metals and alloys minimize that field’s impact on the item that’s being shielded. Used in a variety of different settings, these metals create a straightforward way for the magnetic field to serve its purpose without interfering with it. Acting as magnetic field conductors, they allow both the field itself and the equipment that’s operating in it go about their business without interfering with on...
