Description   Ferrous metals and alloys are iron-based materials that are used in a wide variety of industrial applications.   Types   Ferrous metals and alloys can be divided into iron, and iron alloys and materials.   Iron   Iron is a soft, silvery metal that is the fourth most abundant element in the Earth’s crust. Pure iron is unobtainable by smelting, but small amounts of impurities can make iron many times stronger than it exists in its pure form.

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of ferrous metals and iron alloys?
6 answers
Answers:
Yes. The number of wrong steel supplied are numerous. I am not allowed to tell about them. Fortunately most disasters have been avoided due to checks. One which could have been really nasty was when welded 316 pipe were supplied instead of seamless pipe. This nearly blew up a large petrochemical plant. Only fast and correct action by a well trained plant crew saved the day.
~Kåre J, Engineering Consultant, Vihals, Norway
Recently, pipe work failures due to incorrect weld filler material and lack of required post-welding heat-treatment, LP steam turbine blade failures due to material removal during refurbishment increasing stresses in and altering resonant frequencies of blades, causing accelerated fatigue during operation.
~Ben G, Metallurgist, Nottingham, UK
Use of medium carbon steels in moving shafts of forming presses where impact & fatigue properties are important beside normal U.T.S, 0.2% Y.S. & %age elongation.
~Raj S, Engineering Consultant, New Delhi, India
Product purchased in annealed condition, but the design required HTSR. Parts failed. Small details like proper inspection of MTR's is critical.
~Mike R, Engineering Consultant, Edmonton, Canada

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using ferrous metals and iron alloys?
10 answers
Answers:
Don't rely on test certificates supplied with materials. Carry out your own sample testing and compare with results for existing 'known to be good' supplies to determine if the materials will perform satisfactorily.
~Ben G, Metallurgist, Nottingham, UK
Make sure you have a strong purchasing agreement with the company. Make sure their Production Process and Process control is certified Work with Samples and Send your own sample instead of asking for theirs
~Hulki CURA, Purchaser, IZMIR, TURKEY
Pending on the application; in my case magnetic properties should be watched for, also CRS tend to scale when submitted to corrosion.
~Mario C, Project Manager, Juarez, Mexico
Specify what is needed, not nice to have and make sure you get what you need. There are still far too many cheats in the marked.
~Kåre J, Engineering Consultant, Vihals, Norway
In designing, consider whether your materials coupling or joining will set up a galvanic load cell.
~Mike R, Engineering Consultant, Edmonton, Canada
Always go for rust free steels like stainless steel for interiors of building.
~Raj S, Engineering Consultant, New Delhi, India
Depends on the use. Traceability and quality control.
~Alan Iannacito, Engineering Consultant, Littleton, CO

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of ferrous metals and iron alloys?
9 answers
Answers:
To identify an 'equivalent' material, ensure all properties relevant to the demands of the application are considered! Preferably compare these with those of existing materials which are known to have performed acceptably in the same application, where these are known/available.
~Ben G, Metallurgist, Nottingham, UK
Need to watch variability from batch to batch (alloy mix) also metal's thickness when purchasing laminated steels; hardness is another that changes, with alloy mix they can be real show stoppers.
~Mario C, Project Manager, Juarez, Mexico
Be sure the product you spec/design is what you ultimately end up with. Meaning, the mill supplied product may be in the annealed condition, but the design requires hardened and stress relieved.
~Mike R, Engineering Consultant, Edmonton, Canada
In case you can't do the heat treatment of steel products for engineering steels then go for appropriate plain carbon steel to avoid unnecessary cost escalations of final products.
~Raj S, Engineering Consultant, New Delhi, India
Composition of the material is the Key source of usage capacity of Steel.... Learning Composition's purpose and effects can make sure you buy the right material for the right usage.
~Hulki CURA, Purchaser, IZMIR, TURKEY
Verify the materials when you have received them. Double check critical properties. Even top suppliers can make mistakes.
~Kåre J, Engineering Consultant, Vihals, Norway
Unless and until one is not sure, do not use alternative metal in manufacturing.
~Ranjeet C, Engineering Consultant, NEW dELHI, INDIA
Understand the fabrication process and end use.
