To avoid the toxic effect of released nickel ions and compounds from conventional stainless steels, nickel-free austenitic stainless steels have been developed. We previously established a new manufacturing process to produce nickel-free austenitic stainless steel that involves nitrogen adsorption treatment. Although the cytocompatibility of nickelfree austenitic stainless steel produced using ...

Cold rolling of austenitic stainless steel results in increase of residual stresses, hardness, and tensile strength and dislocation density. We have studied the response of eddy current impedance to austenitic change, hardness and its lift off phase in stainless steels during cold reductions. A series of samples of austenitic stainless steel alloys were cold rolled and found that only percentag...

In this paper, application of ultrasonic techniques for defect detection in weldments of austenitic stainless steel and maraging steel is discussed. Applications of ultrasonic techniques for characterizing microstructural changes in AISI type 316 stainless steel and modified 9Cr-1Mo ferritic steel; thermomechanical processing of 15Cr-15Ni-2.3Mo-titanium modified austenitic stainless steel (allo...

Paper presents the research of austenitic steel AISI 304after ion nitriding at 400◦C and at t =4h, for the two different variants of samples distribution in the working plasma reactive chamber tube. In order to assess the effectiveness of ion nitriding variants emission spectroscopy – GDOES, surface hardness tests, microstructure research (LM) of nitrided layers were made. It has been found tha...

The present work is concentrated with the dry turning of AISI 304 Austenitic Stainless Steel (ASS). This paper presents the influence of cutting parameters like cutting speed, feed rate and depth of cut on the surface roughness of austenitic stainless steel during dry turning. A plan of experiments based on Taguchi’s technique has been used to acquire the data. An orthogonal array, the signal t...

The energy used to produce austenitic stainless steel was quantified throughout its entire life cycle for three scenarios: (1) current global operations, (2) 100% recycling, and (3) use of only virgin materials. Data are representative of global average operations in the early 2000s. The primary energy requirements to produce 1 metric ton of austenitic stainless steel (with assumed metals conce...

Introduction The mechanical properties of austenitic stainless steels, including the low cyclic fatigue behavior have been a subject of numerous studies [1-8]. Nitrogen addition, in general, increases the fatigue strength by decreasing the stacking fault energy of austenitic stainless steels [6]. The stacking fault energy has a strong influence on the cross slip difficulty, thus it affects the ...

There are many industries where austenitic stainless steel needs to be welded specially in power generation industries. Unfortunately the austenitic stainless welding has several fabrication and metallurgical drawbacks when welded by using conventional fusion welding methods, which can often leads to in-service failure. The most pronounced fabrication faults are hot cracks due to inadvertent us...

This article deals with non-destructive evaluation of austenitic stainless steels, which are used as the biomaterials in medical practice. Intrinsic magnetic field is investigated using the fluxgate sensor, after the applied plastic deformation. The three austenitic steel types are studied under the same conditions, while several values of the deformation are applied, respectively. The obtained...
