Project Introduction

Description:

Type 304 Stainless Steel is the most widely used of the austenitic (chromium/nickel) stainless steels. In the annealed condition it is essentially non-magnetic and becomes slightly magnetic with the application of cold work. Type 304L Stainless Steel is preferred in welding applications to exclude the formation of chromium carbides during cooling in the heat affected region of the weld. These alloys represent an excellent combination of corrosion resistance and fabricability.

Specifications:

Type 304 ASTM A240, ASTM A666, AMS 5513 Type 304L ASTM A240, ASTM A666, AMS 5511

Typical Applications:

Chemical equipment and piping, heat exchanger components, dairy and food handling equipment and utensils, cryogenic vessels and components, architectural and structural applications exposed to non-marine atmospheres

Chemical Composition: (Per ASTM A240)

Processing:

Types 304 and 304L cannot be hardened by thermal treatment. Annealing: Heat to1850o°F to 2050 °F and cool at sufficiently high rates through 1500°F to 800°F to avoid precipitation of chromium carbides. Stress Relief Annealing: Cold worked parts should be stre
