Product Introduction

304 stainless steel, also known as AISI 304 or UNS S30400, consists primarily of chromium (17.5-19.5%) and nickel (8-10.5%), with small amounts of other elements. ASTM A240 304 is a specification for chromium and chromium-nickel stainless steel plates, sheets, and strip for pressure vessels and general applications. ss 304 plate is known for its excellent corrosion resistance. Also having good heat resistance, 304 plate is typically used at a continuous service temperature of about 870°C (1,600°F), with short exposures to temperatures up to about 925°C (1,700°F).

ASME SA 240 type 304 Plate Heat Treatment

Solution Annealing: Solution Annealing is one of the most commonly used heat treatment methods. By heating the 304 stainless steel plate to a temperature range of about 1010°C to 1120°C (1850°F to 2050°F), and then cooling it rapidly, the intergranular carbides inside the material can be eliminated and its corrosion resistance and mechanical properties can be improved.
