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)
DESIGN GUIDELINES FOR THE SELECTION AND USE OF Material Selection Many variables characterize a corro-sive environment i.e., chemicals and their concentration, atmospheric condi-tions, temperature, time so it is difficult to select which alloy to use without knowing the exact nature of the environment. However, there are guidelines:Type 304 serves a wide range of applications.
the latter materials will not last as long as the former, but that is part of the design plan for those plants; i.e., low-cost materials but more frequent replacement versus more-expensive materials having longer service life. For a given type of steel at a specific thickness, the expected service life depends on the maximum temperature to
Martensitic Stainless Steel - an overview ScienceDirect Applications. Martensitic stainless steels (e.g., grades 1.4006 [AISI 410], 1.4021 [AISI 420], 1.4028 [AISI 429], and 1.4125 [AISI 440C]) are used extensively for dental and surgical instruments. These stainless steels can be hardened and tempered by heat treatment.
Plating on Stainless Steel Stainless Steel Plating Combining the conductivity of copper with the strength of stainless steel is valuable for a variety of applications. Copper is useful because it's soft and malleable, which makes it perfect for use with flexible metal materials and objects. It also won't separate from other metals even if it gets bent.
Mar 06, 2008 · Rusty found on SS 420 material with Heat Treatment March 6, 2008. I'm facing a complaint from customer of rusty issue on my part which using SUS420 material. The part process is after turning, heat treatment, grinding and degreasing. Could you help on my queries below.
STAINLESS STEEL BALLS:AISI 420/420C/440CSTAINLESS STEEL BALLS:AISI 420/420C/440C 1. Description Martensitic grades (stainless steel balls) are corrosion resistant and have higher hardness. These grades are Ferro-magnetic. They can be used in water, oil, steam, alcohol. They are mainly used where hardness, strength and wear resistance are required. 2. International Equivalents

Stainless steel grade chart - Atlas SteelsApplications such as acetic acid distillation, pulp and paper machinery, ink and dying processes. 317L is a variation of 317 suitable for heavy gauge welding. Excellent corrosion resistance, equivalent to 304 in the annealed condition and superior if the application involves service in 425C-870C range. Typical applications include expansion
Surface Hardening of Stainless SteelsStainless steel is widely used in applications in which corrosion resistance is of high im-portance. In many end-uses, the material is also expected to have a hard, scratch-resist - ant surface. When improved wear resistance is required, surface engineering provides solutions. Industrially proven processes are available that improve surface
IntroductionOther DesignationsMachinabilityWeldingAnnealingHeat TreatmentHardeningApplicationsStainless steel grade 420J2 is inexpensive and highly corrosion resistant steel. It has good corrosion resistance in mild atmosphere as well as domestic and industrial environments. It is also resistant to dilute nitric acid, carbonic acid, ammonia, crude oil, detergent solutions, vinegar, food acids, several petroleum products, and steam. Stainless steel grade 420J2 is known to possess good strength and reasonable impact resistant properties in hardened and tempered conditions when compared with 440 If you need precision metal materials, you need Tokushu SUS420J2, RB-S are classified as martensitic stainless steels, and their most notable feature is that they can be quenched. They have a high carbon content and can acquire extremely high strength if quenched after purchase. By fine tuning the tempering process, it is possible to endow them with a wide range of mechanical properties.
