Sifat Umum Baja Tahan Karat 304
Alloys 304 S30400 , 304L S30403, and 304H S30409 tabung baja tahan karat are variations of the 18 percent chromium – 8 percent nikel austenitik alloy, the most familiar and most frequently used alloy in the stainless steel family. These alloys may be considered for a wide variety of applications where one or more of the following properti are important:
- Resistance to corrosion
- Prevention of product contamination
- Resistensi terhadap oksidasi
- Kemudahan fabrikasi
- Excellent formability
- Beauty of appearance
- Ease of pembersihan
- High strength with low weight
- Good strength and toughness at cryogenic suhu
- Ready availability of a wide range of product forms
Each alloy represents an excellent combination of ketahanan korosi and fabricability. This combination of properties is the reason for the extensive use of these alloys which represent nearly one half of the total U.S. stainless steel production. The 18-8 stainless steel, principally Alloys 304, 304Ldan 304H, are available in a wide range of product forms including sheet, strip, and plate. The alloys are covered by a variety of specifications and codes relating to, or regulating, construction or use of peralatan manufactured from these alloys for specific conditions. Food and beverage, sanitary, cryogenic, and tekanan-containing applications are examples.
Paduan 304 is the standar alloy since AOD technology has made lower carbon levels more easily attainable and economical. Alloy 304L is used for dilas products which might be exposed to conditions which could cause korosi intergranular in service.
Alloy 304H is a modification of Alloy 304 in which the carbon content is controlled to a range of 0.04-0.10 to provide improved suhu tinggi strength to parts exposed to temperatures above 800°F.Properti Umum
