What is stainless steel 304?
It is the standard “18/8” stainless steel. It is an alloy with a high chromium content, and less carbon content. Higher chromium ensures anti corrosion property, and low carbon content prevents chromium carbide precipitation due to welding. This grade of steel has a large range of properties, suitable for many industries. In fact, it is the most versatile and widely used grade of stainless steel. It has excellent forming and welding properties. It is also one of the most ductile alloys, which allows it to be drawn deeply with ease.
Grade 304L, the low carbon variant, is extensively used to produce heavy gauge components. Grade 304H, the variant with higher carbon content is used at elevated temperatures. Theses grades have excellent toughness.

Apart from these, the alloy exhibits excellent thermal resistance. Grade 304L has remarkable resistance towards carbide precipitation, and thus can be heated at a temperature range of about 870-925 degree Celsius. 304H can also be heated in the temperature range of about 500-800 degree Celsius.
These grades can also be welded very easily, either with or without filler metals. Grade 304L doesn’t even require post weld annealing to increase corrosion resistance. They cannot be hardened by heat treatment. And further, they show excellent corrosion resistance properties because of the presence of chromium.
This grade of steel can be fabricated very easily. It is really tough, exhibiting the property even at very low temperatures. Because it shows excellent properties at low temperatures, it responds very well to hardening by cold working. It surface can be cleaned very easily, and it has an aesthetic value because of its lustrous appearance.
Because of the excellent combination of the above-mentioned properties, the alloy finds application in numerous industries. It is used in food processing equipment because of high corrosion resistance and surface finish that allows easy cleaning. It forms a major part of the beer brewing and wine making industry. It is also used in the milk processing units. It is suitable for making milking machine, containers, homogenizers, and sterilizers. It is also used in the brewing industry, and in the juice industry. For the same set of reasons, it finds application in kitchen appliances. Its ability to resist acids in food components make it an ideal alloy for making coffee containers, refrigerators, utensils, pots, pans, stoves, etc. It also forms a major component of architectural paneling and railings. It is used both for its strength as well as its aesthetic appeal. It is also used in heat exchangers on account of good thermal resistance. Chemical containers used in transportation also use stainless steel 304. It also finds usage in springs and welded screens for mining, quarrying and water filtration. It can also be used in marine environments, to make screws and nuts.
This alloy is one of the most valuable alloys in the industrial sector.
