ASME SA514 standard specification for pressure vessel plates, carbon steel, for intermediate-and higher-temperature service
ASME SA514 grade H plates shall be normalized.

Quenched and tempered steel plate S620QL1 which is in EN 10025-6 technical delivery conditions for flat products of high yield strength structural steels in QT delivery condition.

LR EH40 steel is a kind of hot rolled high tensile strength steel. Higher-strength LR shipbuilding steelcomes in 12 grades of 3 strengths, DH40 is one of the grades. The LR DH40 grade steel plates have yield strength of 56,500 psi (390 MPa), and ultimate tensile strength of 74,000 - 94,500 psi (510-650 MPa).

XAR is available in various grades from 300 HBW to 600 HBW and plate thicknesses from 1/6” to 4” (4 to 100 mm), tailored to particular applications, e.g.

A572 steel has four different grades: 42, 50, 60 and 65. Each of these grades differ in their mechanical properties and chemical composition.

ASTM A588 steel is classified into Class A, Class B, Class C, and Class K. The ASTM A588 steel specification is based on the standard specification for high-strength low-alloy structural steel with a lower yield point of up to 50ksi for applications requiring high strength and corrosion resistance.
