    316L in varrying pH

    I wud like know about the resistence of SS 316l in dilute sulphuric acid(4%) & caustic soda(4%) service? I m talking about a waste whose Ph varies anywhere in between 1 to 14 where this material is going to be used. Temp & pressure conditions r ambient. Can anybody answer in detail plz. I know...

    Cromium

    In stainless steels, specially austenitic, problem of sesitization occurs if we cool slowly in the range of 400 to 700C. Therefore quenching of aust. SS is done commonly from higher temps. In sensitization, Cr combines with Iron which precipitates on the grain boundaries & can cause corrosion &...

    Can pipes be used??

    I wonder wether pipes can be used in Heat Exchangers(Boilers). Since pipes have got greater wall thickness than pipes, I guess they wont be efficient for heta transfer. But wat if pressure requirements r there?? Thanks for ur opinion :)

    getting started

    I did a course of Autocad. But since i didnt use it for a long time, I forgot it. Now i want to have a quick guide which can quickly take me through the more useful commands. Can I have any such guide online. Thanks for ur help:)
