0Cr17Ni12Mo2 (AISI316) and 00Cr17Ni14Mo2 (AISI316L) cold hardening characteristics

Comparison of Cold Working Hardening Characteristics between 0Cr17Ni12Mo2(AISI 316) and 00Cr17Ni14Mo2 (AISI 316L)

Austenitic stainless steels are widely used in various engineering fields due to their excellent corrosion resistance, strength and ductility. 0Cr17Ni12Mo2 (AISI 316) and 00Cr17Ni14Mo2 (AISI 316L) are two of the most widely used austenitic stainless steels. In this article, we will compare their cold working hardening characteristics and their impacts on the properties of respective materials.

0Cr17Ni12Mo2 (AISI 316) is an austenitic stainless steel that contains both nickel and molybdenum. It is well known for its excellent corrosion resistance and its high workability and ductility. As for its cold working hardening characteristics, it possesses superior formability to that of other stainless steels and offers excellent toughness. This allows it to be cold worked to a higher degree, and thus results in an increase in its yield strength, while not affecting its tensile strength. In addition, the cold working of 0Cr17Ni12Mo2 (AISI 316) is easier as compared to other stainless steels, as it offers good ductility, even at lower temperatures.

As for 00Cr17Ni14Mo2 (AISI 316L), it is an austenitic stainless steel that contains lower amounts of nickel and molybdenum than 0Cr17Ni12Mo2 (AISI 316). It is known for its superior corrosion resistance, excellent machinability and high ductility, making it suitable for a range of engineering applications. Its cold working hardening characteristics are similar to that of 0Cr17Ni12Mo2 (AISI 316). It is capable of being cold worked to a higher degree, resulting in an increase in its yield strength and an increase in its tensile strength. Additionally, it is still able to maintain good ductility at lower temperatures when compared to other stainless steels.

Overall, 0Cr17Ni12Mo2 (AISI 316) and 00Cr17Ni14Mo2 (AISI 316L) have similar cold working hardening characteristics. Both are capable of being cold worked to a higher degree, resulting in an increase in their yield strengths. Additionally, they both possess good ductility at lower temperatures, allowing them to be easily worked and manipulated. However, 0Cr17Ni12Mo2 (AISI 316) has higher workability and ductility, making it easier to cold work and manipulate. This makes it the ideal choice for engineering applications that require higher strength, as well as excellent corrosion resistance and formability.

AISI 316 and AISI 316L are two stainless steel alloys widely used in industrial applications due to their high resistance to corrosion and their good mechanical properties. They belong to the austenitic grade and are composed of up to 17.5% chromium and up to 12% Nickel with additional elements such as iron, carbon and manganese according to their composition.

When it comes to cold working hardening, AISI 316 (00Cr17Ni12Mo2) shows a lower degree of hardening compared to AISI 316L (00Cr17Ni14Mo2). This behavior is related to the variations in the alloy composition, which increases the level of hardening in AISI 316L due to its higher levels of carbon, nickel and chromium. As a result, AISI 316L can be a better choice when cold working processes are intended to be performed.

AISI 316, however, is highly appreciated for its higher level of resistance to corrosion in aggressive environments. This property is attributed to the presence of molybdenum, which has a beneficial effect in increasing the alloys resistance to pitting and crevice corrosion.

In spite of their different hardening behavior, AISI 316 and AISI 316L have good welding properties, enabling their use in many applications such as the manufacture of chemical equipment, tanks, pressure vessels, industrial milieu and other products that must perform well in corrosive environments. Both materials can be heat treated and respond to all conventional hot working processes saving costs and increasing the productivity.

In general, AISI 316 and AISI 316L are two excellent alloys for industrial implementations, however the differences in their composition need to be carefully considered in order to select the material that best matches the required competence for each application.
