Chromium-Nickel Austenitic Stainless Steel 1Cr18Ni9 Physical Properties

Physical Properties of 1Cr18Ni9 Chromium-Nickel Austenitic Stainless Steel

1Cr18Ni9 is a chromium-nickel austenitic stainless steel, one of the most popular ferrous alloys. 1Cr18Ni9 is used in a variety of applications from medical to heavy industrial fabrication. It is non-magnetic and oxide-resistant, especially in alkaline and acidic environments. It maintains high corrosion, heat and oxidation resistances, making it an excellent all-purpose alloy.

The primary physical properties of 1Cr18Ni9 stainless steel include corrosion resistance, fatigue strength, and tensile strength. The corrosion resistance is provided by its chromium content, which is needed to prevent attack by oxygen and nitrogen at the surface. Additionally, its nickel content provides additional resistance and helps to inhibit chloride-induced stress corrosion cracking. The fatigue strength and tensile strength of 1Cr18Ni9 stainless steel are dependent upon its composition and tempering. As a general rule, the higher the austenite content and the greater the refining and texture of the stainless steel, the more ductile and tensile strength it will have.

One of the key features of 1Cr18Ni9 is its ability to weld easily. It can be joined to other materials or formed into desired shapes without a significant loss of strength or ductility. Additionally, its relatively low hardness makes it ideal for use in cold working applications.

In terms of machinability, 1Cr18Ni9 stainless steel is rated a lower than other steels, making it more difficult to cut but also resulting in a superior finish when machined. It can be tapped, reamed, turning, threading, and drilled easily.

The thermal expansion range of 1Cr18Ni9 stainless steel is relatively high at 13 x 10-6 mm/mC and is also very ductile in high-temperature applications. Its melting point is above 1370°C and its coefficient of thermal conductivity is about 26.4 W/mK.

With its versatile range of mechanical and physical properties, 1Cr18Ni9 has a wide range of applications, from surgical instruments and medical equipment to industrial components and construction materials. Its excellent corrosion and heat resistance and its ability to maintain its strength and ductility in a wide range of applications make it an ideal all-purpose material.

The physical properties of 1Cr18Ni9 Austenitic Chromium Nickel steel are relative. And this steel contains an 18% of chromium, a 9% of nickel and a 1% of carbon. With this combination of elements it has a few different physical properties.

First of all strength: 1Cr18Ni9 Austenitic Chromium Nickel steel has a good resistance to corrosion and is able to resist much more than other types of steel.
