β’ One Career Tip from Top Professionals : Elon Musk Story
#1 -Engineering Learning
Why are top engineers paid a premium?
The Premium of True Engineering
Itβs like hiring a smart accountant.
You pay them a little upfront.
But they save you 10x in taxes.
True engineers do exactly this.
Their knowledge saves massive project costs.
Savings that dwarf their salary.
Let me share a quick story.
It proves this exact point.
The -48Β°C Problem
Do you remember the material selection module?
From the Advanced Control Valve Course.
We discussed temperature and corrosivity separately.
Here is why that matters.
Today's lesson will make that easy.
Here was the core issue:
- Fluid was strictly non-corrosive.
- Minimum design temperature was -48Β°C.
Now, consider Low Temperature Carbon Steel.
LTCS has a lower limit of -46Β°C.
We were short by just 2Β°C.
Because of this tiny 2Β°C gap?
LTCS was deemed entirely unusable.
The vendor suggested upgrading to SS316.
For one valve, no big deal.
But for hundreds of valves?
It was a massive cost adder.
Questioning the Requirement
I decided to apply the Elon Musk rule.
Always question the requirement.
Why does ASME limit it to -46Β°C?
I dug deep into the codes.
And I found something amazing.
ASME has an exception for this limit.
β Perform a Charpy V-notch test.
β Test it at -48Β°C or -50Β°C.
β If it passes, you can use LTCS.
The Solution & The Savings
I went back to the vendor.
I asked if they could do this test.
Their reply surprised me. "No problem, we can comply."
We avoided the massive material upgrade.
We stuck with standard LTCS.
And we saved thousands of dollars.
The Final Lesson
I am not sharing this to boast.
Iβve made plenty of "dumb mistakes" too.
But I want to inspire you today.
Question the standard requirements.
Dig deeper into the codes.
Make your designs significantly better.
And make them far more cost-effective.
This is just the surface.

#2- Engineering Standard
πFor the above story, let us Geek Out.
And Understand exactly what does the ASME standard say.
What is Charpy V Notch Test
The Charpy V-Notch Test
This is how we bypass it safely.
How we use the Charpy V-Notch test.
β Cool a sample of your LTCS.
β Drop it to your target -48Β°C.
β Strike it to check for brittleness.
If it absorbs the impact energy safely?
ASME legally approves that specific batch.
It is certified for your colder project.
#3 -Career Tip
Elon Musk Challenged an Expert and Won.
Let me share a brilliant true story.
From Walter Isaacsonβs biography on Elon Musk.
Elon was reviewing rocket design materials.
He was studying material sciences independently.
And he became fascinated by Stainless Steel.
He asked his top engineers a question. "Why use Carbon Fiber instead of Stainless Steel?"
The experts gave the standard answer.
They insisted Stainless Steel is too heavy.
The High-Temperature Advantage
But Elon pushed back on the experts.
He knew it resists very high temperatures.
The minor weight penalty was manageable.
The rocket's Thrust could still lift it.
The engineering team strongly resisted.
But eventually, they ran the tests.
And guess what they realized?
The self-taught CEO was right.
The Self-Taught Power
They immediately switched to Stainless Steel.
This created an unexpected secondary benefit.
- They could easily hire standard welders.
- Assembly became drastically faster and cheaper.
Here is what I learned from this.
Elon was the CEO of the company.
He was not a formally trained materials expert.
But his approach was incredibly powerful.
β He questioned the strict requirement.
β He engaged in deep self-study.
This led to a dramatic engineering output.
What I Leave You With Today
Never think you cannot learn something new.
Formal training is not the only path.
If you are genuinely passionate about learning.
You will always find a way to learn it.
