we used the steel shaft with ST 50-1 for ten years in agitator application. And now want to change a new one. i would like to use new for 2-3 month.Can i downgrade to use it in short or not (low price)? and what kind of steel grade ? Thank.

In my idea I choose the SMC490. It's ok or not ?

Help me to buy the steel shaft ST50-1 1.0531 I want to buy the nearly spec. in JIS Code. Thank for all.

I find the potential cause is higher load on shaft from process design (more radius load on pump. discharge valve less %opening.) how to increasing strength on shaft if base on material improvement ??
