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...

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 ...

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...

Stainless steel reinforcing has an elevated chloride threshold and is an attractive alternative for prestressed concrete applications. However, due to the high strength requirements for prestressing strands, concern exists about the possibility of stress corrosion cracking (SCC). This investigation screened for potential SCC development three candidate high strength alloys for use as prestresse...

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...

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...
