ASTM Standards: Steel Metallurgy and Heat Treatment
This live online training course is offered by ASTM International.
This two day course is designed to teach the basics of steel metallurgy and heat treatment to improve your ability to correctly write and review steel specifications when ordering or specifying steels based on ASTM Steel Standards.
These goals are achieved by studying more than 40 Connecting-the-Standards© Examples covering more than 60 ASTM product specifications, general requirements specifications, test methods, practices, and terminology standards.
Learning Outcomes [+]
After completing this course, you will be able to:
- Correctly identify steel phases and microstructures in carbon and alloy steels as defined and used in ASTM steel standards
- Recognize the different types of steel heat treatments as specified ASTM steel standards, their functions, terminology, and requirement
- Identify all referenced ASTM steel standards required to be addressed when specifying heat treatment and any additional requirements for mechanical properties
- Associate each metallurgical condition and heat treatment requirements in ASTM steel product specification and its general requirements specification
- Navigate ASTM steel standards to identify mandatory, nonmandatory, and purchaser selected supplementary or additional heat treatment requirements.
- Distinguish how ASTM steel standards differ metallurgical condition and heat treatment with varying wrought product forms (e.g., plate/sheet/strip, pipe, shapes, forgings, etc.)
- Explain the roles of chemical elements in carbon and alloy steels and their effects on metallurgical condition and heat treatment
- Identify when grain size is required in ASTM steel standards, explain how to measure it, and how to obtain it through heat treatment
- Explain why the anisotropic behavior of steels affect mechanical testing requirements for tension, impact, hardness, and bending
- Explain how ASTM A370 for mechanical testing of steel products addresses the anisotropic behavior of steels
- Specify appropriate heat treatment to achieve the specified mechanical properties of wrought steels to overcome their anisotropic behavior.
Who Should Attend
This course is designed for all personnel involved with steels and particularly ASTM Steel Standards, such as, engineers, inspectors, QA/QC coordinators, NDE examiners, purchasers, inventory control personnel, tradespeople, manufacturing, fabricating and repair companies, engineering procurement companies, construction companies, and others working in most industries that use steel, including: civil construction (buildings, bridges), pressure equipment, ship building, water treatment, pipelines, oil and gas industries (oilfield, upgraders, refineries, etc.), chemical plants, petroleum refining, petrochemical plants, power plants, pulp and paper plants, fertilizer plants, and many others.
