Steel is a very common material all over the world and it is a material utilized throughout the construction of a lot of architectural fabrications.
There are a number of sub-categories of this steel and as per the different characteristics and qualities of a particular development the preference of steel selection may vary.
The characteristics that vary the most in various steel types are strength, hardness, ductility, aesthetics, and the price. In accordance with the scope of work, choosing the proper steel kind for the task can benefit the quality of the project and price.
Exploring the Stainless steel:
It is a steel alloy with a least of 11.5 wt% chromium content. This type of steel does not corrode, stain or rust as effortlessly as common steel, but it is not stain-proof. It is also known as corrosion resistant steel when the grade and alloy type are not detailed, predominantly in the aviation industry. There are various surface finishes and grades of stainless steel to meet the surroundings to which the material will be subjected in its existence. General uses of stainless steel are watch straps and cutlery.
Stainless steel is different from carbon steel in the amount of chromium it contains. Carbon steel get rusted when exposed to moisture and air. This film of iron oxide is active as well as accelerates corrosion by creating more iron oxide. Stainless steels contain enough amount of chromium in it so that a passive film of chromium oxide develops which prevents more corrosion.
Exploring the Mild steels:
Carbon steel, in lot of cases recognized as ‘plain carbon steel’ or else ‘mild steel’. The Steel Institute and American Iron defines a carbon steel as containing barely 2 % carbon and no other substantial alloying constituent. Carbon steel formulates the biggest part of steel production and is utilized in a broad range of applications.
Generally, carbon steels are strong and stiff. Moreover, they exhibit ferromagnetism (that means they are magnetic). This indicates that they are broadly utilized in motors and other electrical appliances. Welding mild steels having carbon content more than 0.3 % requires that special safety measures should be taken. However, welding mild steel creates far fewer problems than the welding of stainless steels. The carbon steels have poor corrosion resistance (that means they rust) and so they ought to not be utilized in a corrosive environment except some kind of protective coating is utilized.
Distinction between mild steel and Stainless steel
- Stainless Steel is less malleable as well as harder than mild steel
- Mild steel can additionally made strengthened with the addition of carbon
- Stainless steel is extra resistant to oxidation
- Mild steel s less fragile than steel
- The main difference is that stainless steel has very little carbon and is alloyed with nickel, chromium, molybdenum and various other elements to enhance its chemical and mechanical properties.
So, where and why do we use the Mild Steel?
- If you are not supposed to see the steel surface, i.e. the finishing piece is going to be coated or painted.
- If you have requirement of steel for structural modules that are internal to the piece and not effecting or visible the overall visual model.
- If a piece needs a large amount of metal, where stainless steel is not much cost effective.
- If you are welding or bending the metal
