Video Rotatech vs Leading brand

On reflection I think I'll stick with chains from rob wherever possible from now on

No worries at all. What would it take to change you mind?

A better attitude toward members of the forum, especially ones who have sponsored the site and who help others and aren't just here to go on about their product all the time

Hey Rob, what's up? Feeling bitter your sales are down?

 

Professional.

 

Also I've never had a chain corrod in any form before it's ran out of life in the teeth. Even on rarely used polesaws.

from what i can work out from the picture you show is an oregon 73 lpx cutter so all your doing is getting drive links and tie straps from somewhere else without oregon on them?? so really isnt this an oregon chain??

Exactly. Chain oil seems to stop mine rusting. Even though my use is intermittent never had any problems.

Also bluing is not really very good at corrosion prevention. It's more a cosmetic thing.

Dan, it was banter; he is our friend. I love helping people and spend a few hours a day doing so. You (or anyone else) is welcome to private message me on here or on facebook. If people want to talk to a specialist they can call 0114 278 9090.

This might be because all the top brands of chainsaw chain use blued steel. Cheaper chains don't.

The Rotatech is our own chain that we have developed with careful research and listening to customer feedback. To get the optimum design, it has ended up being similar to Oregon. Both chains are good quality, but the Rotatech costs roughly half the price.

Chain oil is great at preventing rusting. It forms a protective seal between the steel and the oxygen in the air. However we have chosen to add another protective layer onto the steel through the bluing process.

 

I agreed that the blued steel looks good, but that isn't why we decided to use it on our chains.

 

I'm not sure how much you know about steel or chemistry. Apologies is this sounds condescending. I am not an expert in steel, but I am from Sheffield (birthplace of steel) and studied science.

 

Corrosion is the process of oxidation (loss of hydrogen for those that remember school) or the gaining of an oxygen. The bluing process creates a surface of oxidation and forms magnetite (Fe3O4). Just like aluminium does naturally, which is why it always looks shiny and doesn't corrode/rust in your cupboard.

 

This blued steel is therefore resistant to corrosion, scratches and yes it does look nicer.

 

The Wikipedia page is great, https://en.wikipedia.org/wiki/Bluing_(steel)

 

Oregon and Stihl have both chosen to use blued steel, probably for the same reasons.

 

I hope that helps.

Hi Northernarb

No it didn't sound too condescending.

I studied engineering, and earn my living as an engineer, so I have a little knowledge of metallurgy and chemistry.

I standby my original statement that bluing offers minimal corrosion resistance, only a couple of micron thick so hardly a game changer. It does as you say slightly protect against scratching.

Its a relatively cheap, easy process and adds a pleasing finish to the chain. No one wants to shell out their hard earned money on a tatty product and bluing does take your chain into the Stihl and Oregon category on looks. I guess we just have to differ on its other benefits.

 

Far more important would be the composition of the steel, heat treatment and chrome plating. I'm sure you will agree a good quality chain will be more reliable and stay sharp for longer than one made from inferior materials.

 

Rather than a dubious race perhaps a measure of longevity might be interesting.
