This paper presents a series of tests on cold-formed stainless steel bolted connections. The test specimens were fabricated from three different types of stainless steel, including austenitic stainless steel EN1.4301 (AISI 304) and EN1.4571 (AISI 316Ti having small amount of titanium) as well as lean duplex stainless steel EN1.4162 (AISI S32101). The material properties of the three types of st...

A new maraging stainless steel with superior strength-toughness-corrosion synergy has been developed based on an innovative concept of alloy design. The high strength-toughness combination is achieved by forming dispersive nano-sized intermetallic compounds in the soft lath martensitic matrix with a slight amount of residual austenite. The good corrosion resistance is guaranteed by exactly cont...

The inhibitive and adsorptive properties of Sesmum indicum eco-friendly oil for stainless steel corrosion in hydrochloric acid was investigated using weight loss technique as well as electrochemical technique. The result has proved that the oil is excellent inhibitor for stainless steel in hydrochloric acid. The inhibition efficiency of oil for stainless steel increased with increase the amount...

An important problem in metallurgy of iron and steel is management of hydrated, fine-grained, iron-bearing waste which can be formed as a result of gas scrubbing. The article presents a model of application of converter slurry in a closed-circuit flow system. The correct preparation of slag, namely briquetting with defined additives, allows for application of such slag in the steel-making proce...

This experiment assesses the suitability of square-welding high strength steel using deep penetra-tion welding method, RapidWeld. The aim this method assessment was to compare final material properties three welds, welded accordingly identical procedures. High strength, ultra-fine-grain S1100QL (XABO 1100) used as a parent metal. con-firmation based on achievement requested mechanical ISO 15614...

An attempt made to optimize the operating parameters involved in an autogenous pulsed Nd: YAG laser welding process of similar and dissimilar combinations of butt joint of 2 mm thick 316 L stainless steel and mild steel. Influence of prominent laser welding parameters such as average peak power, defocus position, spot position, and shielding gas were investigated for welded joints considered. T...

in this study, the effects cold rolling and annealing parameters during thermomechanical processing of the aisi 201ln stainless steel were investigated. the cast samples were homogenized, hot-rolled and solution-annealed to acquire a suitable microstructure for the subsequent thermomechanical treatment. unidirectional and transverse multi-pass cold rolling at 25, 0 and -15 °c was carried out to...
