What is x20cr13 material?
X20Cr13 is a martensitic stainless steel with good hardness, strength, and corrosion resistance, commonly known as 1.4021, AISI 420, or 2Cr13. Its composition includes high chromium content (12-14%) and low carbon content (0.16-0.25%). The low carbon content gives it good corrosion resistance and polishability, while high hardness can be achieved after heat treatment, making it suitable for applications such as cutting tools, surgical instruments, pump components, and turbine blades.
X20Cr13 equivalent material
The primary equivalent material for X20Cr13 is AISI 420 in the US, while other international equivalents include SUS420J1 in Japan, 2Cr13 or 20Cr13 in China, and 420S29 in the UK.

What is the hardness of X20Cr13 after heat treatment?
After heat treatment, the hardness of X20Cr13 can range from approximately 44 to 52 HRC, depending on the specific process and desired properties. A typical hardness for the hardened and tempered condition is 44–50 HRC, while some sources indicate it can achieve up to 52 HRC for optimal wear resistance.
What is the price of X20Cr13 steel per kg?
The price of X20Cr13 steel typically ranges from USD 2.00 to 2.50 per kg, depending on factors such as the order volume, surface finish, and the supplier. Prices can vary due to fluctuations in raw material costs, global steel market trends, and shipping costs. For bulk orders, discounts of 5–10% are often available, allowing for more cost-effective purchasing. It's recommended to request a quote directly from suppliers to get the most accurate pricing based on your specific requirements.Mail:es@gescosteel.com
