No options of this product are available.
About the Course
This two day course is designed to teach the basics of stainless steels 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 80 Connecting-the Standards© Examples covering more than 40 ASTM product specifications, general requirements specifications, test methods, practices, and terminology standards.
By the end of this course you will be able to:
- Correctly categorize stainless steels as being austenitic, ferritic, martensitic, duplex, and precipitation hardening, as defined and used in ASTM steel specifications
- Explain the roles of chemical elements in stainless steels for corrosion resistance and heat resistance applications
- Recognize the different types of ASTM stainless steel standard specifications, practices, test methods, guides, terminology, and their functions
- Distinguish how ASTM stainless steel specifications and grade designations differ or are similar to others, like AISI, UNS, ASME, SAE, EN, etc.
- Identify common ordering information required by ASTM stainless steel standards, e.g., condition, finish, dimensions, grade or UNS designation, specification designation and date of issue, etc.
- Associate each ASTM stainless steel product specification with its general requirements specification
- Navigate ASTM stainless steel standards to identify mandatory, nonmandatory, purchaser selected supplementary requirements, and any additional purchaser requirements;
- Distinguish how ASTM stainless steel standards differ with varying wrought product forms (e.g., plate/sheet/strip, pipe, shapes, forgings, etc.)
- Distinguish between a heat of steel and lot of steel, as well as between a steel’s heat analysis and product analysis
- Explain how the ASTM A370 standard for mechanical testing of steel products is used for different forms of stainless steels and why they may need to be modified for specific stainless steel properties.
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.
- How are the 5 categories of stainless steel defined and used in ASTM steel standards? (Austenitic, ferritic, martensitic, duplex, and precipitation hardening stainless steels.)
- What are the different types of ASTM stainless steel standards available to assist with purchasing and specifying? (ASTM standard specifications, practices, test methods, guides, terminology, and their functions specifically for stainless steels.)
- How are ASTM stainless steel product specifications and grades designated and how do they differ from other designation systems like AISI, ASME, SAE, and others?
- What are a stainless steel heat, heat analysis, heat number, steel lot, and product analysis, as defined in ASTM steel standards?
- How are stainless steels uniquely different for corrosion resistance and heat resistance applications, and how do ASTM stainless steel standards address these applications?
- What are the roles of common chemical elements in each of the 5 categories of stainless steels and how do they differ between corrosion resistance and heat resistance applications?
- Why do some chemical elements have requirements specified as a minimum value, maximum value, or minimum-maximum range value?
- What are the different stainless steel condition and heat treatment requirements specified in ASTM standards?
- How and why are stainless steel finish requirements specified in ASTM standards?
- How are NDE, pressure testing, and other QC testing requirements specified in ASTM stainless steel standards?
- How and why product sizes, dimensional limits, and tolerance requirements are specified in in ASTM stainless steel standards?
- How is ASTM A370 Standard for Mechanical Testing of Steel Products used with product specifications for:
- tension testing (and referenced to E8);
- impact testing (and referenced to E23);
- hardness testing (and referenced to ASTM E10, E18, E110, A833, A956, A1038); and
- bend testing (and referenced to E190 and E290)?
- How are products required to be marked and certified in accordance with ASTM stainless steel standards, including multiple marking?
