I believe the reason for that is , when the implements etc were made back then it was "virgin" metals . Nowadays we have reclaimed metal in just about everything . Problem with reusing metal is it is changed at a molecular level several times and impurities etc become more common .It is pretty amazing how long some things can stand being exposed to weather and survive well-
My father bought a brand new F-150 in 1976 . That was one of the first years of using "recycled" metals in autos . In 5 years it had the "rust cancer" . Just like the majority of the 76-77 F-150s .I agree,when I worked in the junkyard that had a lot of 1920's and up vehicles,I was often amazed at the condition of many of the metal parts,despite being exposed for decades,they survived incredibly well..and even bolts that looked hopeless to remove,would often come off with your fingers,after cracking them loose with a wrench too..fender dents pounded right out too,unlike the "hard" metals used on 1981 and up vehicles that cant be hammered back ,or even brazed,they must be MIG welded..
We sold original brake drums often from aincient vehicles,that were perfectly usable after a light turning to remove surface rusting,despite being outside longer than I have been alive too!..everything was virgin steel,up until the late 60's,then things started going downhill...
I notice everything built in the past 20 years with high percentages of recycled metal not only corrodes very quickly,it also is weaker,cracks easily..My brothers 2002 GMC truck is already SO rusty underneath the brake backing plates are thin as paper and porus,the frame has a thick layer of scaly rust that is peeling off in sheets ,like delaminating plywood,and every steel fuel,tranny and brake line looks so crusty they may pop any day now!...
.for a truck only 7 years old,you'd think it was dipped in acid--my '82 GMC doesn't look as bad in some places as his does already!(but is suffering the same fate sadly)...you should see a 5 year old 20' car trailer he bought brand new,the square tube is so thin in places it will soon need reinforcing already,and the fenders rotted off it two years ago and have been replaced already too..I know the road salt they are using here is as bad as muriatic acid on steel,but still,you'd think it would last longer than 5 years..its all due to the metal being recycled crap,IMO-..salt never ate steel up this fast in previous years..
I have to agree and disagree . To get the same quality as "virgin" steel , the actual companies that do the reclaiming would spend more money because of sorting etc to ensure a product that met the same standards . So yes , they , as well as manufacturers will cut corners leading to an inferior steel .Regarding "early rusting" of newer equipment. There's no reason for newly made recycled iron or steel items to corrode away early... other than the alloying done when the metals are reclaimed. Steel or iron made today from scrap can be as good or better than that of the 19th century if the specifications for the downstream use of the metal calls for it.
Metals do not lose their strength or resistance to corrosion properties in resmelting if properly handled and alloyed. The same options of strength vs. cost were available to Mr. Seiberling when he spec'ed out the alloy for that tractor seat, we know which way he and most of the manufacturers went back then. The ones that didn't have long since lost their models to the scrapper or nature.
BUT why would a company making tractrors/implements today want it to last as long as that tractor seat in our "obsolesence oriented society"? Can't make no money manufacturing stuff that lasts forever nowadays... You'd be all out of "NEW! BETTER! BIGGER!" advertising and sales. Company stockholders think limiting sales-resales-resales is just dumb. Today's marketing ideas and purposes are an entirely different universe than in Mr. Seiberling's day.
How about chromium or molybdenum ? It's more than just adding nickel .Stainless steel comes by way of adding nickel to steel. The more nickel added, the higher the quality of stainless steel and the more rust resistant it is.
The best steel comes from a mixture of old steel with freshly smelted iron ore. Steel plants have a constant need for scrap in order to produce the steels we use today.
SJ says I have to play nice so I'll do my best. raying:How about chromium or molybdenum ? It's more than just adding nickel .
And once that metal is reclaimed , is ALL the nickel ,chromium, and molybdenum able to be removed ? Or is there always going to be "trace" elements in that "new" steel . Are they getting all the impurities and other metals out or is there going to always be something in there that shouldn't be ?
It's all a moot point . Todays products are made with inferior materials . intentional or not .
Lol , I'm well aware of "70 percent virgin iron ore and 30 percent recycled steel ". I'm also aware of the addition of alloys . Different alloys have been added for centuries .SJ says I have to play nice so I'll do my best. raying:
You apparently have little knowledge about steel because if you did, then you'd know that the steel plants ADD alloys to the steel they make. You'd also know that new steel is made from 70 percent virgin iron ore and 30 percent recycled steel.
Metalurgy has come a long, long way since that old tractor seat was cast, which brings up another point. That seat is actually cast iron which isn't the same as steel anyway. And when it comes to stainless steel, my local scrapyard pays more for it then it does for regular steel so obviously, the stainless feeds a totally separate market in the steel recycling biz. Now, do I expect any of the above to sway your mindset? **** no!!!! I learned how to recognize tunnelvision a long, long time ago.
Anyway...... here's a link that won't interest you one bit.
One need not be a scientist or hold a degree in order to make observations and research a subject to draw a conclusion . And assumptions of someones knowledge or lack thereof is not conducive to a civil discussion of any subject . Brow beating does nothing more than taint a discussion .You apparently have little knowledge about steel
