ABS GRADE A shipbuilding steel pipe
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 pipes have yield strength of 34,100 psi (235 MPa), and ultimate tensile strength of 58,000 - 75,500 psi (400-520 MPa). All the ABS/A shipbuilding Steel offered by Katalor Industry can be certificated by American Bureau of Shipping(ABS).
