Project Description

Ⅰ. Introduction

ASTM A285 steel plate is a kind of pressure vessel steel plate with low and intermediate-tensile strengths which can be made by killed, semi-killed, capped, or rimmed steel practices at the producer’s option.

 

Ⅱ. Size of ASTM A285 Steel Plate

The maximum thickness of astm a285 steel plates is limited to a maximum thickness of 2 in. [50 mm] for all grades.

And the length and width need to be made according to both customer’s needs and the manufacturers’ production capability.
