ASME SA553 Type I Ni-alloy steel plates for pressure vessels

SA553 Type I

SA553 Type I in the standard SA553/SA553M is a kind ofNi alloy steel plates materialused to fabric high temperature pressure vessels, the composition of Ni is 8% and 9%. SA553 have two types . They are : type I and type II . SA553 Type I need to be done the (Quenching + Tempering ) heat-treatment to meet the property requirement in the standard ASME SA553/SA553M.

ASME SA553/SA553M Type I Abstract :
This specification covers 8 and 9% nickel alloy steel plates for use in the water quenched and tempered condition intended for the fabrication of welded pressure vessels. The materials shall be available in two types, namely Type I and II, having different chemical compositions. The maximum thickness of plates is limited only by the capacity of the material to meet the specified mechanical property requirements. The material is susceptible to magnetization and the use of magnets in handling after heat treatment should be avoided if residual magnetism would be detrimental to subsequent fabrication or service. The steels shall be killed and shall conform to the fine austenitic grain size requirement specified. The plates shall be tempered and hardened by heat treatment. The specimens shall be subjected to tension and Charpy V-notch impact tests.
