  • Austenitic Stainless Steel an overview ScienceDirect

    Austenitic stainless steels are widely used in many industries because of their good mechanical properties and excellent corrosion resistance. However, weld decay, which is severe intergranular corrosion due to sensitization in the heat affected zone (HAZ), is a conventional and momentous problem during welding of austenitic stainless steels.

  • Difference Between Austenitic and Martensitic Stainless

    Jul 03, 2019 · Summary Austenitic vs Martensitic Stainless Steel. Austenitic stainless steel is a form of stainless steel alloy which has exceptional corrosion resistance and impressive mechanical properties, while martensitic stainless steels is an alloy which has more chromium and ordinarily no nickel in it.

  • Stainless Steel High Temperature Resistance

    Jan 08, 2002 · In general the quite high thermal expansion rates of the austenitic stainless steels mean that fabrications in these alloys may have more dimensional problems than similar fabrications in carbon or low alloy steels, in ferritic, martensitic or duplex stainless steels. The non austenitic stainless steels also have somewhat higher thermal

  • What is the difference between austenitic, ferritic, and

    Certain alloy elements, most notably nickel, are able to stabilize the austenite phase down to room temperature. This is the major difference between 300 and 400 series stainless steel; 300 series grades contain enough nickel to stabilize austenite at room temperature and hence are termed austenitic
