What is the equivalent of ASTM A387 alloy steel Grade 12?

As a pressure vessel grade steel for use in elevated temperature service, ASTM A387 Grade 12 material is used in a variety of industries and is highly effective, particularly in the oil, gas and petrochemical industry, where liquids and gases are often stored at higher temperatures.

ASTM A387 Grade 12 Steel Chemical Composition

A387 Gr 12 steel equivalent

ASTM A387 alloy steel Grade 12 steel plate is applied in temperature range(316℃-593℃). The elevated temperature properties of it is still of paricular interest, even with the current trend towards applications with high cvn toughness requirements. ASTM A387 steel tend to be fin grain, low silicon, low sulfur, calcium treated and occasionally produced Q&T to give the highest levels of toughness.
