Hello! I'm new to this forum, and I hope it's gonna be very usefull!!!
My question is the following: I'm working in a paper mill that manufacture cardboard with 100% recycled paper... We have a lot of trashes into this waste paper (staples, steel wires, pieces of glass, sand....) and we are experiencing a hard time with the gate valves installed on the filtration equipments that take care of removing these trashes from the paper pulp... The gate in the valve is wearing very fast, and eventually was leaking, so we decided to go for a stronger material, Astraloy. It seems to work pretty fine, but we received a proposal from a valve supplier who told us that his new gates mades of 17.4PH stainless steel will last longer... Does anybody can give me advices regarding this steel grade? I never worked with that kind of steel before, and I'm wondering it it's really gonna last longer? The gate needs to work in normal temperatures (between 40 and 60celsius) and very often needs to cut (when closing) steel wires, staples, cardboard boxes wires, tie-wraps, small pieces of glass...... Please give your opinion! Thanks so much!
