Stainless steel 1.4021
X20Cr13, also known as 1.4021 stainless steel, is a carbon stainless steel with a sulfur content of 0.030%. Certain alloys with higher sulfur content are preferred for specific applications, such as welding and machining. However, a low sulfur content is still sufficient for some applications. Here are some examples of the best alloys for different uses.
The X20Cr13 grade is a heat-resistant stainless steel with a 12% chromium content. It displays a good resistance to steam and sulphur compounds, but loses its elasticity and hardness at temperatures above this range. Although this type of stainless steel can be used in extreme environments, its softness is a limiting factor. Consequently, it is not recommended for applications in a chloride-containing environment.
SS X20Cr13 has excellent corrosion resistance. It is heat resistant up to 825 degrees and has good resistance to sulphur compounds. It is machinability and air and water steam resistance. It is suitable for high-temperature applications, including bolts, but not for marine conditions or chloride exposure. If you're looking for a durable and corrosion-resistant alloy, X20Cr13 is a great choice.
Hot Forged Stainless Steel Bar is also available in DIN EN 420/X20Cr13/1.4021/420S37/420J1. We stock all three versions of this alloy in our inventory, and we can ship it to you at your convenience. The higher the carbon content in the X20Cr13, the harder it will be after it is subjected to heat threatment.
AISI 420 is a martensitic, chrome-alloyed steel with a carbon content of 0.20 percent. It is an ideal material for many applications, including blades. X20Cr13 has good corrosion resistance and is ideal for spring-loaded knives. All three versions of AISI 410 are heat-resistant. The higher the carbon content, the more hard the knife will be.
AISI 420 is a martensitic, thermal-improved, and precipitation-harden stainless steel. The material has good machinability, high strength, and good corrosion resistance. As a result, X20CR13 is suitable for many different applications. The machining of SS420 can be done easily. Unlike AISI 430, it is easier to grind and polish.
AISI 420 is a popular stainless steel grade and is one of the most popular martensitic steels in the world. It comes in several forms, but the most commonly used forms of AISI 420 are AISI 4.2A, 4.2B, and 4.0D. Stainless steel X20Cr13 contains 0.20 carbon and can be age-hardened at low temperatures.
AISI 420 grade consists of a minimum of 12% chromium content. Its corrosion resistance is moderate and can reach up to 650 degrees Celsius. The standard tempering temperature for AISI 404 is 850 degrees Fahrenheit, but 620degC is the maximum tempering temperature. In addition, the alloy can be annealed at 735-750°C.
