ABS for American Bureau of Shipping is also known as A131,
which is used almost exclusively in shipbuilding.
It has a minimum yield of 34ksi(235Mpa). It is used in barges,
ship construction and marine equipment.
Marine steel plate refers to structural steel used in ship building. It is considered a marine grade
and must be able to resist corrosive effects that are common in a water environment.
To achieve this, special alloying elements are added to these grades in order to defend agaist corrosion.
While most carbon steel is not suited for marine environments, there are several marine grade carbon
steels that have been approved by the different societies for shipbuilding applications.
Higher strength- Grade AH, DH ,EH and FH witha specified minimum yield point of
46 ksi(315Mpa),51ksi(350Mpa) or 57 ksi(390Mpa) Shapes and bars are normally
available as Grade A,AH32,and AH36.Other grades may be furnished by agreement
between purchaser and the manufacturer.

ASTM A131 is A structural grade of steel plate utilized almost exclusively in the shipbuilding industry.
This grade is defined as ordinary strength with specified minimum yield of 34KSI(235Mpa).
Applications include barges, marine equipment and ship construction.
These grades are also certified by the American Bureau of Shipping(ABS)
