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.

The plight of the customer today

Today, the quality of goods and services is degrading at an alarming rate. The customer ends up being the sufferer in the midst of dubious practices. They find themselves struggling with high commission, and poor quality of the supplied material. The middlemen often mislead the customers. The alloys are not available with most of the suppliers at the time when the order is placed. The customers have to wait for days, sometimes months, for the products. And even after the long wait, they are delivered products which tend to fail under high pressure. The goods are seldom inconsistent with ASTM standards. There are no mill reports to support the claims about the quality of goods. The levels of hardness are very inappropriate.They are often lost after the delivery of products, as they have no one to attend to their after sales grievances.The goods take forever to be delivered and when they are, they tend to lose their economic value on account of poor, unprofessional packaging. They lose their lustrous surface and appear corroded. They also have reduced strength than that at the time of dispatch.Also,unfortunately, many times, the products fail to meet the ASTM standards. Lack of proper knowledge often results in the supply of wrong grades, with inappropriate hardness. The alloys have the poor surface finish and often, scrap metal is supplied without proper treatment. There is no warranty associated with the product and hence, the suppliers turn indifferent towards the customers as soon as the products are dispatched. There is no control on quality and testing. The growing distress amongst the consumer is an example of the impact of false claims and promises.
