Australoid Steel S30120 1Cr17Ni8 Mechanical Properties
316 austenitic stainless steel is a grade of stainless steel used in the fabrication of articles that require superior mechanical properties and corrosion resistance, in particular, pitting and stress-corrosion resistance properties. Other grade of stainless steels (such as 304 or other grades of austenitic stainless steels) offer superior corrosion resistance but cannot provide the mechanical properties offered by 316 stainless steel. Australoid Steel S30120 1Cr17Ni8 is a grade of austenitic stainless steel similar to 304 but with improved mechanical properties that make it ideal for use in applications needing superior mechanical strength in applications such as processing, transport, storage and related engineering operations.
Austenitic stainless steels are steels with a structure characterized by the presence of ferrite and austenite phases. These phases are formed by the extrusion of nickel and chromium. Each of the phases contributes to the mechanical properties of the austenitic stainless steel in specific ways. In austenitic stainless steels, the ferrite phase provides strength and corrosion resistance while the austenite phase provides formability and ductility.
Australoid Steel S30120 1Cr17Ni8 is an austenitic stainless steel with a composition of 1% chromium, 17% nickel and 8% manganese. It offers good formability, excellent strength and ductility in temperatures ranging from -200 to +400C, excellent corrosion resistance and toughness up to room temperature and pitting resistance up to 600C. The mechanical properties offered by Australoid Steel S30120 1Cr17Ni8 are superior compared to those of other stainless steels such as 304 or 304L. The superior mechanical properties ofAustraloid Steel S30120 1Cr17Ni8 are mainly related to the formation of the ferrite-austenite constituents.
Australoid Steel S30120 1Cr17Ni8 has a tensile yield strength of 565MPa, ultimate tensile strength of 650MPa, and a minimum elongation of 35%. It also offers a fatigue limit stress of 691.5MPa and a fatigue limit strain of 10%. The good wear resistance and hardness of Australoid Steel S30120 1Cr17Ni8 enable it to offer superior resistance to corrosion fatigue, wear due to foreign materials and environmental corrosion.
Australoid Steel S30120 1Cr17Ni8 can be hardenable by cold working, and also is nonmagnetic. The mechanical properties of Australoid Steel S30120 1Cr17Ni8 make it suitable for use in applications where superior mechanical strength and excellent pitting resistance, as well as superior wear resistance and hardness, are required. Examples include food processing equipment, automotive components, oil and gas pipelines, wastewater processing systems and chemical processing equipment.
In conclusion, Australoid Steel S30120 1Cr17Ni8 is an austenitic stainless steel offering superior mechanical properties compared to other grades of stainless steel. The superior mechanical strength and pitting resistance, combined with good wear resistance and hardness, make it suitable for use in a range of industries and applications that require superior mechanical strength, excellent corrosion resistance and superior wear resistance.
