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..

HyMu 80 is a high-performance, magnetic shielding alloy and unoriented metal with excellent mechanical strength, resistant to both atmospheric and moisture corrosion and particularly resistant to oxidation.   HyMu 80 Properties and Appearance HyMu 80 (alloy 79) is an alloy c omprised of 80% nickel-iron-molybdenum . It is a dark metal with high luster and can often have a gold or brass tint to it. HyMu80 can withstand high temperatures due to its high initial permeability with minimum hysteresis loss. (wastage due to heat in a magnetic environment). HuMy80 is popular when being used for shielding electrical components from magnetic fields as it is an unorientated metal so will reverse polarity to avoid any magnetic attraction to other metals.  Chemical Comparison Physical Properties Mechanical Properties Thermal Properties HyMu 80 Applications The main characteristic of HyMu80 is high permeability, which is used for shielding against static or low frequency magnetic fields....
