1.4301 / DIN X5CrNi18-10 – AISI 304 – UNS S30400
1.4301 (304) is the most common and versatile stainless steel in the world. It has excellent formability and welding ability. The austenitic structure of 304 enables deep spinning without intermediate annealing. Therefore, it is preferred in productions that require deep plastering such as sinks, natural gas chimneys and handled pots. It is used for different purposes in sectors such as architecture and transportation.
304L is a type of 304 with less carbon. Nickel ratio is slightly higher than 304. The austenitic structure provides these qualities with excellent toughness and even maintains its toughness at crojonic temperatures. It is partially difficult to process, 304L is more difficult to process than 304.
Corrosive resistance of 304 and 304L in normal atmospheric environment is very good. In hot environments with acid content, it is likely that the material will form capillary cracks and pits in the internal structure, and when the temperature rises above 60 ° C, cracks due to stress may occur. Resistant to 200 mg / L of chlorine at standard temperature, 150 mg / L above 60 ° C.
1.4301 (304) has good oxidation resistance in environments with continuous heat of 925 ° C, which reaches 870 ° C intermittently. However, if the environment is watery and there is a temperature of 425-860 ° C, the corrosion resistance decreases. Since 304L has low carbon, no carbide precipitation occurs in these environments.
After the annealing process is heated between 1010 - 1120 ° C, it is cooled rapidly. It cannot be hardened by heat treatment due to its low carbon content.
Shows excellent ability in all welding methods, for example; electrode, gas or wire etc. The most suitable electrode or wire quality for 304 is 308, for 304L is 308L. When welding 304 quality thin sections, it does not require post-welding annealing, but it must be applied in thick sections. On the other hand, 304L does not require post-weld annealing in thick sections.
Food processing equipment, part of the brewing industry, as well as milk processing and wine making; In kitchen, boat tools and equipment (sink, armature, pots, handrail etc.); In architectural exterior cladding (panel, rail, etc.); In chemical transport containers; In heat exchangers; In bolts, nuts, screws; It is used in springs.
