● SAE 304 RVS is de meast foarkommende RVS. It stiel befettet sawol chromium (tusken 18% en 20%) en nikkel (tusken 8% en 10.5%), metalen as de wichtichste net-izeren komponinten. It is in austenitysk roestfrij stiel. It is minder elektrysk en termysk geleidend as koalstofstiel. It is magnetysk, mar minder magnetysk as stiel. It hat in hegere corrosie ferset as gewoane stiel en wurdt in soad brûkt fanwege it gemak wêryn it wurdt foarme yn ferskate foarmen
● De komposysje waard ûntwikkele troch WH Hatfield by Firth-Vickers yn 1924 en waard ferkocht ûnder de hannelsnamme "Staybrite 18/8".
● It wurdt spesifisearre troch SAE International as in part fan syn SAE stiel klassen. Bûten de FS is it ornaris bekend as A2 roestfrij stiel, yn oerienstimming mei ISO 3506 foar befestigingen.[3] Yn 'e kommersjele cookware-yndustry is it bekend as 18/8 roestfrij stiel. Yn it unifoarme nûmersysteem is it UNS S30400 De Japanske lykweardige klasse fan dit materiaal is SUS304. It is ek spesifisearre yn Jeropeeske noarm 1.4301.
Stainless Steel 304 1.4301
● RVS 304 en RVS 304L binne ek bekend as respektivelik 1.4301 en 1.4307. Type 304 is it meast alsidige en breed brûkte RVS. It wurdt noch wolris oantsjut mei de âlde namme 18/8 dy't ôflaat is fan 'e nominale gearstalling fan type 304 dat 18% chromium en 8% nikkel is. Type 304 roestfrij stiel is in austenityske klasse dy't serieus djip tekene wurde kin. Dit pân hat resultearre yn 304 as de dominante klasse brûkt yn tapassingen lykas wasktafels en pannen. Type 304L is de lege koalstof ferzje fan 304. It wurdt brûkt yn swiere gauge komponinten foar ferbettere weldability. Guon produkten lykas platen en pipen kinne beskikber wêze as "dual sertifisearre" materiaal dat foldocht oan de kritearia foar sawol 304 as 304L. 304H, in fariant mei hege koalstofynhâld, is ek beskikber foar gebrûk by hege temperatueren. Eigenskippen jûn yn dit gegevensblêd binne typysk foar plat rôle produkten bedekt troch ASTM A240 / A240M. It is ridlik om te ferwachtsjen dat spesifikaasjes yn dizze noarmen ferlykber binne, mar net needsaaklik identyk oan dy jûn yn dit gegevensblêd.

1.1.2 Corrosie Resistance
304 has excellent corrosion resistance in may environments and when in contact with different corrosive media. Pitting and crevice corrosion can occur in environments containing chlorides. Stress corrosion cracking can occur above 60°C.
1.1.3 Heat Resistance
304 has good resistance to oxidation in intermittent service up to 870°C and in continuous service to 925°C. However, continuous use at 425- 860°C is not recommended. In this instance 304L is recommended due to its resistance to carbide precipitation. Where high strength is required at temperatures above 500°C and up to 800°C grade 304H is recommended. This material will retain aqueous corrosion resistance.
1.1.4 Fabrikaasje
Fabrication of all stainless steels should be done only with tools dedicated to stainless steel materials. Tooling and work surfaces must be thoroughly cleaned before use. These precautions are necessary to avoid cross contamination of stainless steel by easily corroded metals that may discolour the surface of the fabricated product.
1.1.5 Kâld wurkjen
304 stainless steel readily work hardens. Fabrication methods involving cold working may require an intermediate annealing stage to alleviate work hardening and avoid tearing or cracking. At the completion of fabrication a full annealing operation should be employed to reduce internal stresses and optimise corrosion resistance.
1.1.6 Hot wurkjen
Fabrication methods like forging, that involving hot working should occur after uniform heating to 1149-1260°C. The fabricated components should then be rapidly cooled to ensure maximum corrosion resistance.
1.1.7Machinability
304 has good machinability. Machining can be enhanced by using the following rules: Cutting edges must be kept sharp. Dull edges cause excess work hardening. Cuts should be light but deep enough to prevent work hardening by riding on the surface of the material. Chip breakers should be employed to assist in ensuring swarf remains clear of the work. Low thermal conductivity of austenitic alloys results in heat concentrating at the cutting edges. This means coolants and lubricants are necessary and must be used in large quantities.
1.1.8 Warmtebehanneling
304 stainless steel cannot be hardened by heat treatment. Solution treatment or annealing can be done by rapid cooling after heating to 1010- 1120°C.
1.1.9 Weldability
Fusion welding performance for type 304 stainless steel is excellent both with and without fillers. Recommended filler rods and electrodes for stainless steel 304 is grade 308 stainless steel. For 304L the recommended filler is 308L. Heavy welded sections may require post-weld annealing. This step is not required for 304L. Grade 321 may be used if post-weld heat treatment is not possible.
