Types of Steel

Types of Steel

Type 304
One of the most widely used and oldest of the stainless steels. This was originally called 18-8 which stoof for its chromium and nickle content. It possess an excellent combination of strenght, corrosion resistence and fabricability.


Type 316 
This austenitic has an added molybdenumcontent to increase its resistance to corrosion, when compared to other 300 series alloys.It will resist scaling at temperatures up to 1600 F. 316 is used in the marine industry for its resistance to corrosion. It is widely used in the marine/ pharmaceutical and laboratories


Type 430
is a simple corrosion and heat resisting grade and finds application in areas where a mildly corrosive conditions occur or where scaling resistance at moderate temperatures is required.


Special high chromium and nickel alloyed grades resist scaling and retain strength at hight temperatures.


Lower alloyed grades resist corrosion in atmospheric and pure water environments, while high alloyed grades can resist corrosion in most acids, alkaline solutions, and chlorine bearing environments.
Properties which are utilised in process plants.


The easy cleaning ability of stainless steel makes it first choice for strict hygiene conditions such as hospitals, kitchens, abattoirs and other food processing plants.


The hardening property of authentic grades that results in a significant strengthening of the material from cold working alone, and the high strength duplex grades, allow reduced material thickness over conventional grades, therefore savings on costs.


When the total life cycle costs are considered, stainless steel is often the lest expensive material option. Stainless steel products complete their service life. There is less concern about disposal since this material is 100% recyclable. In fact over 50% of new stainless steel comes form old remelted stainless steel scrap thereby completing the full life cycle.
