the welding characteristics of austenitic stainless steel: the elastic and plastic stress and strain during the welding process are very large, but cold cracks are rarely seen. there is no quenching hardening zone and grain coarsening in the welded joint, so the tensile strength of the weld is relat

sometimes the cable ladder is installed through the wall. if one side of the wall catches fire, heat may be transferred from the fired side to the other side of the wall, causing danger. therefore, a test was conducted on a device that simulates a hollow wall. the cable ladder passes through the ins

observing the actually installed ladder frame, it is found that although the cable ladder frame is protected by fire, the supporting legs are not insulated and can conduct heat. the test was carried out on aluminum and stainless steel ladder frames covered with 100 mm ceramic fiber insulation. the l

in the event of a fire, the structure of the building may have to withstand the test of heat radiation instead of being directly burned by the flame. in order to simulate this condition, each ladder frame bears a uniform load (same as the aforementioned test), and then directly receives the heat rad

in order to obtain comparative data of the four familiar structural materials exposed to severe fire conditions, darchem engineering co., ltd. (a test laboratory approved and certified by the british national measurement and appraisal system) was entrusted to carry out the test on the cable ladder (

the corrosion-resistant steel was first developed 100 years ago when the effect of adding sufficient chromium in steel to the corrosion resistance of steel was studied. these early chromium-containing steels were very promising. they combined a bright appearance with outstanding corrosion resistance

the economy and safety of stainless steelsince the beginning of the industrial age, the safety of structures and the protection of personal safety have always been extremely important things for engineers. despite the accumulation of two centuries of experience, these issues are still people's main

how to choose piping materials in seawater desalination？the main influencing factors of seawater corrosionseawater is a complex natural balance system, a corrosive electrolyte solution, with high salt content, conductivity and biological activity. therefore, seawater is highly corrosive, and its cor

the demand for water and electricity in desert and arid regions of the world is increasing due to increased population and the expectation of high living standards. de-salination plants that are also power plants use the heat extracted from the generation process to evaporate seawater. the desa
