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)
420 Stainless Steel - MatWeb420 Stainless Steel Categories:Metal; Ferrous Metal; Heat Resisting; Stainless Steel; T 400 Series Stainless Steel. Material Notes:16.0 mm diameter bar, austenitized at 980°C for 30 minutes, oil quench, temper for 2 hours at 28°C above test temperature
420 stainless steel is a hardenable, martensitic stainless steel with corrosion resistance similar to Type 410. It has a higher carbon content to increase strength and hardness over Type 410. Maximum corrosion resistance only in the fully hardened condition or fully hardened and stress relieved condition.
AISI 316 Stainless Steel Properties, SS 316 Grade Density AISI 316 stainless steel has higher strength and higher work hardening rate than carbon steel and low alloy steel, so it is more difficult to process. Therefore, greater power and lower processing speeds are required, which may result in shortened tool life and difficulty in obtaining a smooth surface.
High Temperature Properties Stainless SteelSoftening or loss of strength occurs in the 300 series (304, 316, etc.) stainless steel at about 1000° F and at about 900° F for the hardenable 400 (410 <, 420, 440) series and 800° F for the non-hardenable 400 (409, 430) series (refer to Table 1). Carbide precipitation can occur in the 300 series in the temperature range 800 1600° F.

I. Stainless Steel GradesII. Stainless Steel ClassificationIII. Stainless Steel Mechanical PropertiesIV. Detailed Introduction to Stainless Steel420 Stainless Steel McMaster-CarrThis material is hardened for increased wear resistance over standard 420 stainless steel. Suitable for making molds, 420 stainless steel is a hard, wear-resistant material that can be finely polished to a very smooth surface. It maintains its corrosion resistance in temperatures up to 1150° F.. For technical drawings and 3-D models, click on a part number.
What is Strength of Stainless Steels - Yield - UTS Yield strength of ferritic stainless steel Grade 430 is 310 MPa. Yield strength of martensitic stainless steel Grade 440C is 450 MPa. Yield strength of duplex stainless steels SAF 2205 is 440 MPa. Yield strength of precipitation hardening steels 17-4PH stainless steel depends on heat treatment process, but it is about 850 MPa.
Nov 05, 2020 · A240 304 Stainless Application scope. System description:A240 304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot workability such as stamping and bending., No heat treatment hardening phenomenon (use Stainless Steel - Grade 420 (UNS S42000)
IntroductionKey PropertiesCompositionMechanical PropertiesPhysical PropertiesGrade Specification ComparisonPossible Alternative GradesCorrosion ResistanceHeat ResistanceHeat TreatmentWeldingMachiningApplicationsGrade 420 stainless steels are welded using welding rods, coated with grade 420 metals, to achieve high-strength joints. During the process, steels are pre-heated at 150 to 320°C and post-heated to 610 to 760°C. In the as welded condition, parts are welded using grade 309 filler rods to achieve ductile joints. However, grade 309 electrodes or rods are recommended for welding grade 420 steels by AS 1554.6.420 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.
