It is also used in the manufacturing of medical; electronic and food processing products that require a combination of both corrosion and wear resistance.
Grade 420 Stainless Steel Oversize provides great corrosion resistance when polished, grounded or hardened . High carbon content and chromium makes for the hardest available stainless steel grade available. Grade 420 stainless steel can be further improved with a series of steps such as hardening, tempering and polishing. 420 stainless is preferred when used in shear blades, needle valves CA40(420) Hardened Investment Casting Alloy Casting Dec 11, 2019· CA40 (420) hardened is a 400 series stainless steel investment casting alloy.

It is magnetic in both the annealed and hardened conditions. Maximum corrosion resistance is attained only in the fully hardened or fully hardened and stress relieved condition. It is seldom used
420 stainless steel is a martensitic higher carbon version of types 410 and 416 stainless that can be hardened by heat treatment. It contains a minimum of 12 percent chromium, sufficient to give 420 corrosion resistance properties. It has good ductility in the annealed condition but is capable of being hardened up to 50 RHC.Precision Ground Stainless Steel McMaster CarrHardened for superior wear resistance, these rods are precision ground to a tight diameter tolerance so theyre ready for turning in a lathe. 420 Stainless Steel. Also called flat stock, these precision ground bars are held to tight thickness and width tolerances.Stainless Steel Grades and FamiliesExplained Unified These stainless steel alloys offer moderate to good corrosion resistance and remain magnetic after hardening. Common grades of martensitic and precipitation hardening steels include 410 and 420
Nov 16, 2013· I'm getting a little confused. . .the only pre hardened stainless I have purchased is type 416. All other 400 series came in the annealed condition, where it machines a little tough, but can be cut with hss or carbide. Use the c6 carbide as the material acts more like tool steel than stainless.Compare 20 Grades of Knife Steel ThoughtCoJul 30, 2019· High carbon stainless steels, this grade of stainless can be hardened to a greater degree than 420 grade steel, allowing for greater strength and wear resistance. 440A is used in many production knives because of its edge retention, ease of resharpening, and corrosion resistance.Surface Hardening of Stainless Steelsapplied to duplex and precipitation hardening stainless steel grades. Materials to be treated by low temperature carburising should be in the solution annealed condition. Sharp edg es, the inside of bores and gaps present no limitation to the process [4, 11, 12, 13].

Like Stainless Steel 410 it is also considered a general purpose grade including at least 12% chromium, which is enough to give it acceptable corrosion resistance. Typically, Stainless Steel 420 achieves its best corrosion resistance when the alloy is hardened and polished, or surface ground.
