SA/AS 1548 - 7-490NL XLERPLATE®

Product Description and Features

A fully killed, fine grained carbon - manganese steel for boiler and pressue vessel applications, produced by normalising. It has a guaranteed minimum tensile strength of 490 MPa. Australian Standard AS1548-1995 pressure grades have been approved by ASME. To demonstrate compliance with ASME rules, grades require the addition of the "SA" prefix to the AS1548 grade name, consequently plate test certification and stencil are prefixed with "SA". This page also refers to grade SA/AS1548 - 7-490NL20, SA/AS1548 - 7-490NL40, SA/AS1548 - 7-490NL50.

• Guaranteed tensile strength levels
• Grades with elevated temperature properties available
• Grades with low temperature properties available
• Excellent weldability and formability

Produced to: SA/AS 1548

Warnings

• This material should be used in conjunction with the appropriate pressure vessel design and welding standards.
• Guidelines for cold bending, where fracture toughness is important, are given in AS4100 and AS1210.
