It is magnetic in both the annealed and hardened conditions. Maximum corrosion resistance is attained only in the fully hardened condition. It is never used in the annealed condition.420 Martensitic Stainless Steel Bar Interlloy 420 is a general purpose medium carbon straight chromium high hardenability martensitic stainless steel with good strength and fairly good corrosion resistance. It is generally supplied hardened and tempered either in the tensile range 700 - 850 Mpa (condition R) Brinell range 201 - 255, or in the tensile range 770 - 930 Mpa (condition S)
420 Stainless Steeltreatment. 420 stainless has a 13% chromium content which gives the specification a level of corrosion resistance properties. British standard grades available are 420S29, 420S37, 420S45. We also supply European stainless steel specifications 1.2083 and 1.4034, both which have a higher carbon content and achieve a good Rockwell hardness when
Heat treatment temperatures, including the rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each 420 stainless steel component. Other considerations during the heat treatment process include the type of furnace, DESIGN GUIDELINES FOR THE SELECTION AND USE OF 420 S42000 440C S44004 Precipitation-hardening stainless steels (Table 4) are chromium-nickel types, some containing other alloying ele-ments, such as copper or aluminum. They can be hardened by solution treating and aging to high strength.

Grade 420 has poor weldability. Pre-heat to 150-320°C and post-heat at 610-760°C. Grade 420 coated welding rods are recommended for high strength joints, where a post-weld hardening and tempering heat treatment is to be carried out. Stainless Steel 420/ Alloy 420 / UNS S42000Alloy 420 is a martensitic stainless steel of the 12% Chromium type. Due to it's Chromium content 420 will achieve high hardness. Stainless Steels Welding Guide - Lincoln ElectricTypes 403, 410, 416 and 420 are representative of this group. Duplex stainless steels are supplied with a microstructure of approximately equal amounts of ferrite and austenite. They contain roughly 24% chromium and 5% nickel. Their numbering system is not included in the 200, 300 or 400 groups. Precipitation hardening stainless steels contain

Like any other stainless steel, grade 420 can also be hardened through heat treatment. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished, surface grounded or hardened. This grade has the highest hardness - 50HRC - among all the stainless steel grades with 12% chromium.Stainless steel grades that are similar to grade 420 stainless steels420 Stainless Steel Properties KVA Stainless420 - UNS S42000:AISI Type 420 is a martensitic stainless steel that provides increased strength and hardness relative to Type 410, with moderate corrosion resistance. It is magnetic in both the annealed and hardened conditions. Maximum corrosion resistance is attained in the fully hardened or fully hardened and stress relieved condition.
