Heat treatment, stainless and duplex, nickel alloys, pitting, SCC, HTHA, hydrogen damage and material selection

What you'll learn

Explain why a material behaves as it does in service, from microstructure and heat treatment
Select between carbon steel, low-alloy, austenitic, duplex, nickel alloys and titanium on defensible criteria
Assess corrosion mechanisms from the electrochemistry rather than from a lookup table
Diagnose pitting, crevice, galvanic, under-deposit and MIC attack from conditions and appearance
Assess environmentally assisted cracking — chloride SCC, caustic, amine, carbonate and hydrogen mechanisms
Evaluate high-temperature damage including creep, sulfidation, metal dusting and HTHA
Set low-temperature and toughness

Requirements

, and understand impact testing and exemption logic
Specify cladding, weld overlay and lining as an alternative to solid corrosion-resistant alloy
Write a material selection basis that will still answer the question three years later
Feed materials and corrosion knowledge into an integrity management programme rather than leaving it in a report

Requirements

No prior metallurgy or materials background is required — microstructure and heat treatment are built up from the start
Any engineering or technical background is enough to follow the course
No mathematics beyond arithmetic — this is a mechanism and selection course
Helpful but not essential: some familiarity with pressure equipment, damage mechanisms or an inspection programme
No software or purchases needed — no material database subscription is required

Description

This course contains the use of artificial intelligence.
▸ You can list twenty damage mechanisms. Can you say why the metal does that?
Most integrity training teaches damage mechanisms as a catalogue — name, appearance, susceptible materials, mitigation. It works until you meet a case that is not in the catalogue: an unusual service, a material substitution, a weld that behaved differently from the parent metal, a mechanism that appeared where the table said it would not.
At that point you need the layer underneath. What the microstructure is doing. Why heat treatment changed it. Why a sensitised weld heat-affected zone cracks and the parent plate does not. Why duplex has a temperature ceiling and where that ceiling comes from.
This course is that layer. It sits beneath API 571 rather than repeating it, and it exists so that you can reason about a material in a service you have not seen before.
▸ Metallurgy for engineers, not for metallurgists
The metallurgy here is built for people who specify and assess equipment rather than for people who run a laboratory. Phase diagrams and heat treatment are covered because they explain behaviour you will meet on a datasheet and in a failure — not for their own sake.
Every alloy family is covered with its real limits attached: what it is good at, what it costs, what it cannot do, and the specific service that will destroy it. Selection is then treated as a defensible decision with a written basis, because that is the form it has to take when someone asks you three years later why this material was chosen.
Five focused sections, worked through in an afternoon.
▸ What you will master
● Read the iron-carbon system and heat treatment well enough to explain why a material behaves as it does in service
● Interpret mechanical property and toughness test data, and understand what a Charpy result is and is not telling you
● Select between carbon and low-alloy steels, austenitic stainless, duplex, nickel alloys and titanium on real criteria
● Understand the temperature limits of duplex and super duplex, and where they come from
● Explain the electrochemistry underneath corrosion, and use it to reason about a service you have not seen before
● Distinguish uniform, pitting, crevice, galvanic and under-deposit attack and the conditions that drive each
● Assess environmentally assisted cracking — chloride SCC, caustic, amine, carbonate and hydrogen-related mechanisms
● Recognise high-temperature corrosion, creep, sulfidation and metal dusting in the services where they appear
● Assess high-temperature hydrogen attack and understand what the Nelson curves are and are not for
● Specify cladding, weld overlay and lining, and know when they are cheaper and safer than a solid alloy

Who this course is for

● Integrity, inspection and corrosion engineers who want the mechanism layer beneath API 571
● Materials and welding engineers specifying, substituting or approving materials on projects
● Mechanical and pressure equipment engineers writing and reviewing material requisitions and datasheets
● Process and project engineers who make material decisions early and live with them for thirty years
● Reliability engineers investigating recurring failures and needing to explain a root cause properly
● Anyone preparing for API inspector examinations who wants the underlying metallurgy rather than the memorised table
▸ The knowledge that is hard to find
Materials engineering is one of the last genuinely scarce technical skills in the industry. The people who have it are retiring, most companies have stopped employing a dedicated materials specialist, and the decisions are being made by engineers who were given a table and told to follow it. A table is fine until the service moves outside it — which is precisely when the decision matters most.
▸ Why learn it here
Taught by a Chartered Engineer (CEng MIMechE) with over fifteen years delivering safety-critical projects in oil, gas and energy infrastructure — from the perspective of someone who has had to justify material selections on live projects rather than describe them from a textbook.
Material behaviour varies with service, jurisdiction and owner specification, and this course says so throughout. Where a limit is genuinely codified it is identified; where it is accumulated industry practice or a company standard, that is stated plainly.
▸ What you get
● Structured on-demand video across 20 focused lessons and five sections
● A final exam
● All lectures presentations downloadable
● Lifetime access on mobile and TV, and a certificate of completion
▸ No prior metallurgy is required — microstructure and heat treatment are built from first principles, for engineers rather than metallurgists. Any engineering or technical background is enough to follow it.
Enrol now and stop selecting materials from a table you cannot defend.
