Stainless Steels Welding Guide - Lincoln Electric

STAINLESS STEELS Austenitic stainless steels include the 200 and 300 series of which type 304 is the most common. The primary alloying additions are chromium and nickel. Ferritic stainless steels are non-hardenable Fe-Cr alloys. Types 405, 409, 430, 422 and 446 are representative of this group.

Austenitic Stainless Steels - ASM International

Austenitic stainless steels have many advan-tages from a metallurgical point of view. They can be made soft enough (i.e., with a yield strength about 200 MPa) to be easily formed by the same tools that work with carbon steel, but they can also be made incredibly strong by cold work, up to yield strengths of over 2000 MPa (290 ksi).Chapter 2 Basic Heat Treatment - NavyBMR1.0.0 HEAT TREATMENT THEORY All heat-treating processes are similar because they all involve the heating and cooling of metals. However, there are differences in the methods used, such as the heating temperatures, cooling rates, and quenching media necessary to achieve the desired properties.DATA SHEETNormal variations in chemistry, size and heat treat conditions may cause deviations from these values. Recommended Heat Treatment: Austenitize 1950°F (1065°C). Quench to below 125°F (50°C). Double temper at 600°F (315°C) 2 hrs. minimum each temper. Cool to hand warm between tempers. A freezing treatment may be added between tempers.

Ferritic Stainless Steel - an overview | ScienceDirect Topics

The carbon and nitrogen content is kept to a minimum. Similar to austenitic stainless steel, ferritic stainless steel cannot be hardened by heat treatment. They are used either in the annealed condition or in the cold-work condition. The ferritic stainless steels are susceptible to embrittlement when heated to 400 to 540°C (750 to 1005°F).Fundamentals of the Heat Treating of SteelChapter 2: Fundamentals of the Heat Treating of Steel / 11 Steel, however, is by far the most widely used alloy and for averygood reason. Among layman, the reason for steels dominance is usually con-sidered to be the abundance of iron ore (iron is the principal ingredient in all steels) and/or the ease by which it can be rened from ore pdf stainless steels heat treatment chapter 12HEAT TREATMENT OF STAINLESS STEELS - EPrintsHEAT TREATMENT OF STAINLESS STEELS S.
