Chemical composition of medium chromium ferritic stainless steel 00Cr18Mo2Ti and high purity Cr18Mo2Ti

00Cr18Mo2Ti and High Purity Cr18Mo2Ti Ferritic Stainless Steel

Introduction

Stainless steel is an alloy composed of iron, chrome and other metals. The proportions of these materials are important since they define the properties of stainless steel, which make it attractive for a variety of applications. 00Cr18Mo2Ti and High Purity Cr18Mo2Ti are two types of ferritic stainless steel that are widely used in many industrial and commercial sectors. Their chemical composition is similar, but High Purity has a higher chrome content and additional elements, resulting in higher performance and additional applications. In this article, the differences between 00Cr18Mo2Ti and High Purity Cr18Mo2Ti are discussed and their characteristics are compared to illustrate why High Purity is increasingly being used in a variety of applications.

Chemical Composition

00Cr18Mo2Ti is a ferritic stainless steel containing 18% chromium and 2% molybdenum, while the High Purity Cr18Mo2Ti also contains 18% chromium and 2% molybdenum but has a higher chrome content and additional elements. Specifically, the difference in composition is highlighted in the table below:

(Table 1)

Element 00Cr18Mo2Ti High Purity Cr18Mo2Ti

Chromium 18% 20%

Molybdenum 2% 2%

Nickel 0% 0.10%

Cobalt 0% 0.10%

Manganese 0% 0.30%

Tungsten 0% 0.20%

Sulfur 0.03% 0.03%

Characteristics

While 00Cr18Mo2Ti and High Purity Cr18Mo2Ti have similar chemical compositions, they have certain factors that differentiate them and make them appropriate for different applications. The higher chrome content in the High Purity Cr18Mo2Ti increases the corrosion resistance and allows it to be used in environments where high levels of corrosion protection are required, such as in chemical or pharmaceutical industries. This type of stainless steel also has higher mechanical properties, such as tensile strength and elongation, making it more suitable for applications that involve high levels of stress or strain. On the other hand, 00Cr18Mo2Ti has lower mechanical properties, but it is more economical and suitable for applications that involve slightly lower corrosion protection and stress levels.

Applications

Due to their distinct characteristics, 00Cr18Mo2Ti and High Purity Cr18Mo2Ti are used in different applications. 00Cr18Mo2Ti is often used in food processing equipment and containers, while High Purity Cr18Mo2Ti is used in chemical, pharmaceutical and oil and gas industries. Additionally, the higher mechanical properties of High Purity Cr18Mo2Ti make it more suitable for applications such as pipes, pressure vessels, fittings and structural components, while 00Cr18Mo2Ti is used for less robust applications.

Conclusion

00Cr18Mo2Ti and High Purity Cr18Mo2Ti are two types of ferritic stainless steel with slight variations in their chemical compositions. The higher chromium content in the High Purity Cr18Mo2Ti results in higher performance and makes it more suitable for environments that require high levels of corrosion protection or mechanical properties. On the other hand, 00Cr18Mo2Ti has lower properties and is more economical but is used in applications that require slightly lower levels of corrosion protection and stress. These two stainless steels are used in different applications and industries, and the choice of material is dependent on the requirements of the application.

00Cr18Mo2Ti and high-purity Cr18Mo2Ti are chromium steel austenite stainless steels, which have the characteristics of low carbon, high chromium and low nickel content. The two stainless steels have a total chromium content of 18%, and their molybdenum and titanium contents are 2.0% and 0.03% respectively.

00Cr18Mo2Ti stainless steel has good mechanical properties and corrosion resistance, especially its oxidation resistance, and its weldability is also good. It is mainly used in the petroleum, chemical, nuclear, power and other industries. Because of its strong intergranular corrosion resistance, it is also used for food, dairy product manufacturing and other occasions with high cleanliness requirements.

High purity Cr18Mo2Ti stainless steel has the same composition as 00Cr18Mo2Ti, but its impurities are much lower than those of 00Cr18Mo2Ti, so its mechanical performance and corrosion resistance are also significantly improved. It is mainly used in areas that require high corrosion resistance and good formability, such as beer and beverage, machinery and electronics, transportation, energy industry and so on.

The two stainless steels are widely used in different industries, especially in the petrochemical and energy industry. They have good properties of acid and alkali resistance, good weldability, and are widely used in many industrial fields.
