the great debate? is stainless steel best classified as a ferrous or a nonferrous metal? the answer isn\'t so simple.

Some things can\'t be categorized very well, such as the athlete who wears a sweater vest and listens to the English literature class of Dvor and Loretta Lynn, who knows Fellini like the back of his hand.
He moved from one group to another.
Although he was not rejected, he was not fully accepted because no one fully understood him.
In high schools where stereotypes dominate, a person who does not fully integrate into a group tends to confuse his classmates.
Stainless steel can cause the same confusion.
Before being asked whether stainless steel is a ferrous metal or a non-ferrous metal, you may never consider it.
But once faced with this question, you may realize that many factors need to be considered before answering.
Some people may ask: Does this matter in the end?
According to the Definition Characteristic of North American Special Steel Association(SSINA), [Web site www. ssina. com]
Stainless steel is a low carbon steel with chromium content of 10% or more (by weight) and carbon content of less than 1%.
Stainless steel has more than 60 grades, which are divided into five grades defined by alloy elements.
According to SSina, alkaline stainless steel, or ferrite, contains 12% to 18% chromium.
These stainless steels are magnetic, hardened by heat treatment and have poor weldability. They are often used in blades and surgical instruments.
Levels include 410, 420 and 440C.
The content of ferritic stainless steel is less than 0.
2% carbon, although their chromium content remains in the range of 12% to 18%.
Ferrite grade is magnetic, although they are not hot. -
SSina says the material is hardened for use in automobile exhaust pipes, building decorations and cooking utensils.
Grades include 409 and 430.
Austenitic stainless steel contains nickel and higher chromium content.
These brands are non-magnetic, hardened by cold working, have high corrosion resistance and are easy to weld.
According to SSina, austenite grades such as 304, 310, 316 and 317 are used for roofs and sinks, kitchen sinks and chemical containers.
The chromium content of duplex stainless steel ranges from 18% to 26%, and the nickel content ranges from 4% to 7%.
According to SSina, most grades also contain 2% to 3% molybdenum.
These grades are weldable.
Compared with ferrite and austenite grades, they have high stress corrosion cracking resistance and higher tensile strength and yield strength, and are used in heat exchangers and food pickling plants.
The popular score is 2205.
How do you define stainless steel?
Aren\'t you sure after the Introduction to Science class?
Read on, but I can\'t guarantee that things will become clearer.
Gerry Stewart, Executive Vice President of ELG Metals Company in Machispott, Pennsylvania.
\"I don\'t hesitate to say,\" I think it\'s an iron grade.
The iron content of base grade 304 is 75%.
In ferrite grade, iron content can be as high as 85% to nearly 90%.
Bill Sheenan of the Pittsburgh Iron and Steel Recycling Institute agrees.
Seventy percent of stainless steel is usually iron.
If it is iron, how can it be something other than iron?
Michael Marley, Philadelphia\'s second-tier metal editor for the American Metal Market, voted on the steel industry in another round. He also said that the advantages of steel in metallurgy make stainless steel an iron metal.
\"From my point of view, most people who are consumers tend to become members or the steel industry, or to be found in the steel industry,\" Marley said.
He added that the production process of stainless steel was similar to that of electric arc furnace steel.
\"They may require some additional secondary treatment, depending on whether they are argon or not. -
They are using the oxygen decarbonization process, or just the ladle metallurgical process now used by some steel companies, whether to produce stainless steel or carbon steel.
Heenan said that the biggest factor in classifying stainless steel as ferrous metal is the consumption of about 2 million tons of scrap per year.
\"Now, considering the age of 60-
Plus millions of tons. . .
Carbon steel industry[consumes].
Randy Castriota of Castriota Metal Recycling in Pittsburgh said he thought stainless steel was a non-ferrous metal, although the problem caught him off guard.
\"Most nonferrous metals are nonmagnetic, such as copper, brass, aluminium and most of them. --
I\'m not sure about the percentage. --
Stainless steel is nonmagnetic.
\"In the waste yard, stainless steel has hardly ever been in the same pile as scrap iron and carbon steel.
\"The National Association ISRI,\" Stewart said. (
Waste Recycling Industry Association, Washington)
There are two types: non-ferrous metals and ferrous metals.
Our position as stainless steel processors is always confusing.
\"Marley has found little consensus among the industry on this issue.
\"I\'ve talked to people who think it\'s a non-ferrous metal, partly because nickel is such an important driver or price. --
In any case, the price of primary nickel--
What do they care about? Their interests are the way they see things.
Castriota said higher prices for stainless steel would help define nonferrous metals.
Patrick Ryan\'s Notes, Perham, N. Y.
Quickly answer this question and say that stainless steel is a non-ferrous metal. --at first.
Then he reconsidered.
Let me think about it.
It is a ferrous metal.
\"Before the interview was over, he changed his mind again.
Stainless steel ferrous metals and
The controversy over people of color reminds one restaurant customer of his inability to make up his mind: \"I want steak. No, the fish. No, the pasta!
\"Some special\" stainless steel grades are actually iron. -alloys;
They are not steel.
I don\'t think some people use the words properly, \"Ryan said.
Ryan preferred stainless steel to be closer to the underlying alloying elements (nickel, chromium or other metals).
\"It will be more descriptive than stainless steel,\" he said.
\"Because of the value of iron, the value of steel is so insignificant. -
Its alloy content, I think, is iron. -
Alloys, not steel.
All you have to do is look at the price of nickel, \"he said.
\"Carbon steel is the foundation, but when you come into contact with stainless steel, whether it\'s tungsten, nickel or chromium. . .
Hi means that the actual value is the alloy content, not the basic product, steel.
For me, iron or non-iron. . .
It really doesn\'t matter, \"Ryan commented.
For Ryan, the question is: Is stainless steel iron? -
Alloy or steel?
Bob Garino, ISRI commodity director, said, \"Yes, stainless steel is just\'special\'. \" --
In a class.
Perhaps it is because a narrower definition of the stainless steel industry can be compared with all-embracing terms such as \"non-ferrous metals\" and \"iron\". (and should)stand alone.
\"Look at a few factories that produce this waste, as well as fewer waste processors and brokers who carry most of it,\" Garrino continued.
\"For waste products, we need to know not only the intrinsic value of nickel, chromium and molybdenum, but also their overlap points. \" --all nonferrous--
However, in order to calculate the residual value, one must also know the value of iron.
Ferrous may not care much about LME(
London Metal Exchange).
Not so. Stainless steel boys and gifts who focus on LME nickel settlement prices and the percentage of settlement prices used by factories in waste calculation.
\"Of course, this is mainly a steel product, but for most commercial purposes, the emphasis is on non-ferrous metals,\" Garrino concluded.
But, as I mentioned above, it\'s \"special\", so let\'s stop there.
