Boron Content

12/09/2012 5:10 AM

In our project there is a requirement that for wrought carbon steel pipe fittings "Boron content shall be shown in the heat analysis or product analysis and shall not exceed 0.0005%."

What effect does it have.

This question, coming from someone who asked the difference between butt weld and socket weld, is starting to sound suspiciously like homework.

What is your project? If it is a REAL "project" much more information will be needed.

Back to you.

Rock was the first tool for human civilization. Later they discovered metal and found that it was much more harder and stronger than rock and suitable for many other purposes. sunburn is a big problem in the modern world.Whole world is blaming developed countries for this nasty situation. Sea level is increasing due to global warming and by product is sunburn and it may cause skin rashes.In extreme cases it may lead to skin cancer.

Re: Boron content

12/10/2012 10:27 AM

Boron - Definition as required by demand and in this post example is:

Significantly akin to and mimicking "Moron" as in kinda the same but kinda different?

Morons and Borons went to different high schools together at one time or another, maybe? Or maybe not. I can't decide.

The Difference? A moron lacks a high enough IQ to ascertain, reason, and assimulate simple thought processes whereas a Boron keeps posting meaningless "pokes" to stimulate the "Bored" populace and therefore solicit a reactional (reasonable)response to the original OP's question?

How am I doing? Which catagory do I fit in today?

HAPPY HOLIDAYS EVERYONE!!

THANK YOU ALL SO MUCH FOR THE GREAT HELP AND INFORMATION.

Now that I think of it Lyn probably meant you. And yes we know what a troll is and you behave like one.

If you know so much about Boron in Steel then speak up. Don't waste time with trolling around.

This is still an engineering forum and it does not make it better by denunciating other posts. If you have an answer then let the OP know.

Have a good day and have a tea!

I don't want sixth sense to identify who it was!The fellow (OP) who raised the question might have seen something from a literature or from a real practical environment.If,you know the answer give it to him,that's all,so simple and straight forward.Why should we taunt him by asking unnecessary questions for more info. for silly things.I strongly believe that the guy is not going to make an ICBM with a pipeline steel!Unfortunately I don't know the correct answer,but I tried to question many members to bring out the correct answer.So I am satisfied with the final outcome. Btw,I am not believing that all the people those who are participating in this forum are real Engineers!So,people may come with simple questions and that may be too simple for someone.

Have a nice day and Have a tea.Peace.

Re: Boron Content

The effect the requirement has is to filter out any wrought carbon steel pipe fittings where the boron content exceeds 0.0005% so they don't get used.

Re: Boron Content

Boron affects hardness of steel. In simple terms more Boron more hardness.

I Googled 'Boron in steel' and came up with this link

http://www.keytometals.com/page.aspx?ID=CheckArticle&site=kts&NM=214

This is paper 2 and there is a link to paper 1.

Could be interesting reading if the matter is understood. You will need to make your own interpretation. The steel you are using may need to be 'flexible' and allow expansion and contraction. With a higher Borob content you may not get this flexibility and could thus fracture.

Even a small amount of boron in carbon steel will affect its hardness and weldability. It will still be good steel pipe, but you may find it more difficult to fabricate things with it.

They why IIW (International Institute of Welding) forgot to add boron in their CE (Carbon Equivalent) formula??

yep. That's worth a phone call. Do report back with the findings.

Along with making steel harder it makes it more brittle.

The major effect is at higher levels then 0.0005% it will remove the fittings from the wrought carbon steel classifacation in the standards that you are using. Which is the requirement that you state.

Thats really unusual!

Mostly Boron is used to enhance steel's deep drawing quality....

---so why to restrict it?!?!?!

"One question on the boron content, a report said it would control the boron content by weight percentage of B / N in the range of 1.0 to 1.5 can improve the deep-drawing performance. Here, B / N more than 1.5 when the deep-drawing performance degrades too much to add because of the formation of small boron Fe23 (CB) 6, caused by inhibition of the grain growth."

So,I am confused! Meterial Scientists always say contradictory statements!

Re: Boron Content

Ofcourse you are right !

The restriction required for deep drawing is by specifying the Boron minimum content

(of course with high level cleanliness steels) . The ratio specified - is not he only parameter , but important one !! (We would require Rare Elements like Niobium or Tanatalum ,in very small percentage-to enhance significantly the drawing quality)

.......Ofcourse this is not the answer asked by the OP....
