ABS Steels are types of structural steel which are standardized by the American Bureau of Shipping for use in shipbuilding. ABS steels come many grades in ordinary-strength and two levels of higher-strength specifications. All of these steels have been engineered to be optimal long-lived shipbuilding steels. ABS does permit the use of other steels in shipbuilding, but discourages it, and requires more detailed engineering analysis.
However, there are many common misconceptions about the proper terminology for steel grades that can create some confusion when customers place an order. Steel Grades and Standards. Steel is graded by a number of different methods, but the most common standards are ASTM and AISI/SAE.
American Bureau of Shipping/ABS Steel Grades Many of our SSAB facilities carry and maintain ABS certifications to supply ordinary-strength to high-strength steels with improved toughness and Reduction of Area. Our ABS grades are used in the Ship Building(Marine) and mobile offshore drilling units and structures.
Stainless Steel Grades Within families, youll find various grades that help to describe specific properties of the alloy such as toughness, magnetism, corrosion resistance and alloy composition. Older grades often feature a three-digit identifier established by the Society of Automotive Engineers (SAE).
Bethlehem Steel, photo by Michael LaMartin[/caption] Did you know there are over 3,500 different grades of steel? While all steel is composed of iron and carbon, each grade is comprised of unique physical, chemical, and environmental properties.
ABS grade A steel is a kind of hot rolled general tensile strength steel. ABS steels come 4 grades in ordinary-strength steel for shipbuilding and grade A is the lowest one of them. The ABS A grade steel plates have yield strength of 34,100 psi (235 MPa), and ultimate tensile strength of 58,000 - 75,500 psi (400-520 MPa).
Basics of the North American Steel Grade System- Carbon In this post well take a look at the significance of the last 2 digits of the steel grade designation. We will be discussing carbon, not alloy grades.
Understanding the Carbon Steel Grade System Engineering handbooks point out that the classification of steels comes under the authority of the Society of Automotive Engineers (S.A.E.) or American Iron and Steel Institute (A.I.S.I.) for its coding system.
ABS Steel Plate Leeco Steel offers grades that are certified by ABS (American Bureau of Shipbuilding) and represents the Higher Strength Group of ABS steel plate grades AH36, DH36 and EH36. Like ABS steel plate grade A & grade B, these grades of steel plate are almost exclusively utilized in the shipbuilding industry for the construction of structural parts of ships, barges and marine equipment.
ASTM A36 ASTM A36 / ABS Grade A The most common used carbon steel plate grades in the steel fabrication industry. It is easy to be welded and fabricated. Base plates are a key component for any building and this is also the most common grade when it comes to rolling and building tanks.
Deep drawing steel should be used for these deep drawing applications. Extra Deep Drawing Steel (EDDS) Typical Rb range 15/30. For the last of the four common steel grades, there is extra deep drawing steel. This grade is for really severe drawing applications. EDDS really only allows for the product to be hit with a one or two hit draw.
ABS Grades of Steel To include ABS grades of high strength quenched and tempered steels, in line with Part 2, Appendix 3. 2-4-4/5.7 Flange Attachment Welds To allow the size of the external fillet weld to be equal to the thickness of the hub, if the hub thickness is less than 1.1 times the nominal

Understanding steel grades for piping procurement. As industrial processes and applications have matured, industry organizations have developed unique classifications and specifications for the pipe destined for service in those sectors.
Steel Grades Explained Mild Steel Mild steel is the most common form of steel because its price is relatively low whilst it provides material properties that are acceptable for many applications. This steel usually contains less than 0.25% of carbon and insignificant amounts of alloying elements.
Currently, ABS has more than 200 Rules, Guides and Guidance Notes available for download or purchase through the online catalog. You can search the complete current collection of ABS Rules & Guides in our database below, or for older publications, search our separate archived database of ABS Rules & Guides.
The SAE steel grades system is a standard alloy numbering system for steel grades maintained by SAE International. In the 1930's and 1940's, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. These efforts were similar and overlapped significantly.
In the 2004 edition, Part 2 was reorganized to incorporate the new divisions Rules for Testing and Certification of Materials, comprised of Chapters 1, 2 and 3 and Appendices 1, 4, 5, 6 and 7, and Rules
ASTM A131 A&B / ABS A&B marine & offshore steel plate applications include barges, marine equipment, and ship construction. , understanding steel grades abs A structural grade of steel plate , understanding steel grades abs
This grade is defined as Higher Strength with specified minimum yield of 51 KSI. These products are offered in various conditions; AH36 in the control-rolled condition, DH36 in both the control-rolled and normalized condition, EH36 in the normalized condition. These grades are also certified by the American Bureau of Shipping (ABS).
Another widely-used system of bolt strength grades comes from ASTM International, formerly the American Society for Testing and Materials. Its strength grades are indicated by the letter A plus three numerals stamped on the bolt head. Common ASTM grades include A307, which roughly corresponds to SAE Grade 2.
Grade A steel plate is used for shipbuiling's hull structure and platform. The shipbuilding steel plate grade A is the common tensile strength steel. It has good toughness properties and higher strength, strong corrosion-resistance,the processing properties,and welding properties.
ABS Grade A shipbuilding steel plate,ABS A marine steel plate, grade A steel plate for ship building,ABS A ship steel sheet supplier. ABS Grade A shipbuilding Steel Description: ABS Steels are types of structural steel which are standardized by the American Bureau of Shipping for use in shipbuilding.
The EH36 shipbuilding steel plate is the mainly kinds of steel for shipbuilding and oil platform, the shipbuilding grade EH36 can be used in the manufacture of the ship's hull structure, whose weight is more then 10000 tons.
Sir, I am an engineer who worked for ABS and have experience with EH 32. The steel you mentioned I believe is an ABS grade and if you go to www.eagle.org there should be joy. I hope this is helpful. Sincerely Len Andersen lenandersen, understanding steel grades abs 914-536-7101 [email protected]

Stainless steel products complete their service life. There is less concern about disposal since this material is 100% recyclable. In fact, over 50% of new stainless steel comes from old remelted stainless steel scrap, thereby completing the full life cycle.
ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.
