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 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. Table 4 PRECIPITATION HARDENING STAINLESS STEELS UNS UNS S00 S17400 S15500 S17700
HIGH-TEMPERATURE CHARACTERISTICS OF STAINLESS 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
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

Cryogenic Applications. There are a number of petrochemical processes that require operation at low temperature. In ethylene plants, for example, the product is separated by fractional distillation at sub-zero temperature, and towers, drums, piping and heat exchangers may be exposed to temperatures as low as -120°C (-184°F).
The salt spray test and its use in ranking stainless steelsresistant material. It has become a universal test. The reason is that the salt spray test offers numerous advantages. One of the most interesting is that the test is multi-material. For example, it is possible to test a bare material, a painted one and a noble or sacrificial coating [Figure 1].Stainless Steel Grade 420J2 (UNS S42000) - Material Science
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 440 420 Stainless Steel - Online Materials Information Resource420 Stainless Steel Categories:Metal; Ferrous Metal; Heat Resisting; Stainless Steel; T 400 Series Stainless Steel.
